Welcome from 34t
Welcome to the web site of Ray
Stewart and the Heavy Traxx Hire 34T Hypermac Corette.
Over the coming season we hope to develop this site
into an informative and entertaining site. Flying the
flag for the Cromwell Club, Ray has had great success
both in local and national competition.
Updates
17/11/12 We apologise for the lack of update
during the off season, but as many can imagine, it has
been a very busy time at Heavy Trax Hire. As of
today's update, Ray has only managed to make it out to
the Friday night meeting at Woodford Glens 2 dayer,
with the car performing as well as to be expected in
its first outing. Weather permitting, the car will be
out again for the second night. Here is what Ray had
to say in his latest scribe:
Here we are mid October and the opening rounds of the
2012/13 season are underway but 34T is still in the
workshop a new exhaust almost finished and a couple of
other minor things to finish hopefully in time for a
meeting at the Glen on the 27th.
The off season was busy
as usual, stripping the car looking for broken or bent
bits, the diff off to Mike to
be
stripped and checked. The diff is one season old and
the crown wheel and pinion were stuffed. It appears
the current diffs we are buying are Chinese and you
are lucky to get a full season of racing without them
breaking compared to 3 or more seasons we used to get.
Replaced most of the rod ends, bottom bent suspension
arm, new birdcage bearings, a couple bent chassis
tubes, brake pads, etc. No
changes to the suspension and chassis apart from one
new update component from Hypermac. We spent the most
of the last season getting to grips with a set-up and
are pleased where we are with the handling. In Dunedin
and Cromwell we had good drivey tracks that allowed
foot flat racing and showed up any lack of horsepower.
On a few occasions the 415 chevy lost a few car
lengths off the corner and annoyed the shit out of me
so plans were in place to sort this for the coming
season. The motor was left in the car until the new
bits arrived and were all connected to save time later
and then off to the dyno followed by an engine
refresh. First to arrive a new Kinsler injection to
replace the BLP carb that lacked the quicker throttle
response. The injection unit bolted up and the fuel
lines altered to suit. A new ignition arrangement to
complete the package. No changes to the motor which
had all the very best crank, rods, heads and so on so
didn’t think it necessary to buy new heads, yet! I was
gambling on the new injection and ignition to pick up
the torque that gets you off the corner harder and
faster. Off to the Turbo Shop and mount the motor on
the Superflow SF901 dyno with the carb and exhaust
system as raced in the car. Run the motor up to
temperature and load it up for its first power run to
get a base reading to compare with the new mods. Now
the car as raced last season was no slug but the dyno
sheet said otherwise. This was supposed to have 710 hp
from the supplier. Nope. Was it the different dynos or
was the motor down on grunt. Was there something wrong
with the motor compared to what was dyno’ed in the
USA. That first dyno run was to be our lowest readings
over the next two weeks of testing.
Read on its very
interesting.
Some of the other Super
Saloons are reputed to have 750 + horsepower but I
never was concerned about those quotes as we were
competitive with what power we had. The power numbers
differ between dyno’s and can vary a great deal
depending on how the dyno room is set up and the load
testing of the load cell. The dyno is best used as a
measuring tool to develop and make changes then
compare against previous horsepower numbers but on the
same dyno.We had our base numbers as the car was raced
and from here it was make one change at a time then do
a power run and compare. First change, with same carb,
fit sprint headers, walla, horsepower gains right
through the rev range. Straight away we identified our
exhaust system as raced was robbing big horsepower.
Next we fit the Kinsler EFI injection and ignition.
Balance the two banks and start it up. The start up
fuel map was a rough guess but the motor fired up
immediately. Set the ignition timing to 34 deg and
gradually run through the revs adjusting the fuelling
at 500 rpm increments. The fuel map is preset with
Quick Lambda. This is a brilliant arrangement, race
motors on alky have a best air/fuel ration of about
.78-.80 Lambda. With motor held at each rev interval
the Lambda readout is matched to the preset numbers
with the simple touch of a computer key. We are
running a closed loop Lambda that gives instant feed
back on the air/fuel ration plus 8 exhaust gas
temperature (EGT) probes for individual cylinder
temps. With the two instruments to keep an eye on lean
out, we quickly progress from low revs to 7000 rpm at
different throttle settings. Several short power runs
with adjustments to the fuel map, one cylinder reading
780C until more fuel fixed that. More power runs up to
8000 all the time making minor adjustments to the fuel
table. No two motors are the same, some will make more
power with higher EGT than others as we found the
pre-conceived idea of 650 to 680C was incorrect and
750 deg C was closer to the mark. Okay, next power run
with the new injection and ignition plus the sprint
car pipes, yep more torque everywhere. Back to the
original exhaust, yep there goes the horsepower just
to prove the pipes are not good. Now what to do as not
enough time to build or find pipes that will fit this
car and give serious gains without testing and
modifying. Besides I haven’t got a clue what works
best for out of phase firing V8’s. Give me a two
stroke or motorbikes or especially a Nissan FJ20 turbo
and I know what works but this V8 stuff is all new and
I know nothing so best I learn and quick. A crash
course in V8 exhaust design and tuning, hours, no days
on the computer researching and I find some websites
that sets out the theory but one particular site
explains how gas speed and sonic speed are different
but work in unison, why primary and secondary
diameters and lengths shape the torque curve. The name
of the game is harmonics. Depending on the motor
specs, rev range and just about everything else you
can think of, big horsepower pipe design is governed
by harmonic lengths. For this 415 chev the ideal
primary length was 28”, secondary 16.5”. Don’t bother
trying this on your motor as it will differ. There are
worse lengths too which is what the original pipes
were and the reason we were down on HP. The primary’s
control the rev range where the maximum torque and
horsepower will be, the secondary the shape of the
torque curve. Have a look at the top sprint car pipes
and you will see some interesting designs compared to
the average race car. Recently Tri-Y pipes are
appearing here on Supers and Saloons. They are
especially suited for the Saloons who are looking for
every horsepower gain they can find at higher revs.
From all this learning stuff it figures to leave the
primary pipes as they were on the original pipes and
play with the secondary diameter and length. Okay here
we go back on the dyno with all the theory and designs
according to harmonics. Now that 16.5” secondary
length is fine for Dirt Late Model cars that expire
behind the front wheels but we must run mufflers soooo
there are 1st, 2nd, 3rd etc harmonics and best torque
was 16.5” which was 4th harmonic, 3rd harmonic is 33”,
2nd harmonic 66” and so on but the longer the less.
The mig and cut-off wheel got a serious workout,
cutting welding different pipe diameters and lengths
to arrive at the correct harmonic length. We included
a X section, 3” cross, 3.5” 2 into 1, pipes with and
without mufflers, all sorts of combinations burning
thru 2 drums of methanol in the process. We got pretty
good making pipes very quickly. What we learned was
you could spend months on an exhaust system alone
developing one motor for best horsepower. Those
harmonics are for real. We played with the best and
worse length harmonics and they were absolutely
spot-on. One pipe was at 36”, 3” longer than the
recommended 33” 3rd harmonic. We lopped off 3” and
picked up noticeable gains of 3-5 ft/lb, not
everywhere but rounding off some of the dips in the
torque curve. Each time we changed to a different pipe
type and adjusted to the harmonic length, the torque
curve increased. The calculated distance from the end
of the primary pipes to the X then to the mufflers and
atmosphere proved to be the best torque curve. The
secondary pipe mods gave large gains below 5000 rpm
but very little above those revs.
One more change to dyno,
ignition curve then settle on 36 deg. Small gains but
worthwhile. What gains did we make with all the mods!
60 ft/lb @4500, 60-80 hp from 5000 to 7000 rpm. Still
don’t have 750 horsepower though. Pull the motor off
the dyno and down to MV for a fresh-up after a seasons
racing and hours on the dyno. Rob fly’s in on Thursday
to help finish the car and we should get to Beachlands
for the fireworks night.
--------------------------------------------------------------
The Elf Super Cup this
year is raced at 7 tracks, Blenheim, Nelson,
Invercargill, Ruapuna, The Glen, Cromwell and the
final at Dunedin. The entry’s closed with 22 drivers
entered but may drop subject to confirmation of one or
two being ready to race. This is the first year we
have run the 7 rounds so it will be a full season and
also with a full field could be an interesting series.
Trevor Elliott is back after a year off and there are
4-5 new rookies to the Elf Super Cup. The Elf Cup has
become a very competitive series and any one of eight
or so drivers are capable of taking out the overall
series. Hopefully the Hypermacs are on the podium at
each round with Ian Burson, Gary Hill, and ourselves
showing our rears to the others. Grant Flynn and I
have been working on the North versus South Super
Saloons to be raced at Wellington on Friday and
Saturday 22nd & 23rd March the weekend before Easter.
The exact formats for both nights are yet to be sorted
but the Friday night will probably be a final of both
the SSCAR and Elf Cup series with the top 8 drivers
and a wild card from each island racing to find who is
the Top Gun, who is Uno Numero. Saturday night will be
the same drivers in a N v S take no prisoners, team
racing. 2 on 2, 3 on 3, 4 on 4, 8 on 8, all in final
with double points. We are working on it and will let
you know.
Keep an eye on each of
the series to see who the top 8 from each island will
be in the N v S.
Got to
work on the car if I am going to race it.
Cheers
Ray
22/2/12 A very busy season for Ray, but
somewhere in amongst it we managed to get an update
from him.. Here's what he had to say in his latest
scribe:
I'm back. Where did we
get to, oh yeah had my first drive in the new Hypermac
at the Canterbury Champs back in November 2011. Its
been a busy time since then with the Elf Super Cup in
Blenheim and Nelson, Xmas meetings at Cromwell, NZs
at Nelson and GP at the Glen plus the Elf Cup at the
Glen and club meetings. Its taking more time than I
thought to get up to speed in the new car with a few
niggley problems and finding driveable setups for
each track. Its like having to start from scratch
again figuring out what works on this chassis and
learning to drive a new car that requires a different
driving style to the last Hypermac which was easy to
drive. The Hypermacs have a short right side panhard
or left side mounted J bar for axle location that has
proven to be a challenge to get right. This latest
chassis is slightly altered to past ones being
structurally stiffer with altered rear suspension
arrangement and consequently the handling has also
changed. The new cars are wide, harder to drive and
need to be driven harder for them to respond but they
are definitely faster compared to my last car. Several
drivers have mentioned that it takes a season to get
used to driving a new car so it would seem seat time
is the answer to going fast. Ian Burson has the same
chassis but received his new car about two months
before me and this shows with his recent results at
the GP and Hoopla then the Elf Cup at the Glen where
he has been dominant winning most of the races. Both
Burse and I had the same handling problem at the
beginning experiencing a mid-turn push coupled with an
unsettled darty nervous car that no end of changes
would seem to fix. This became frustrating but a
simple change of front tyres cured the push and
handling woes so we could then concentrate on looking
for set-ups.Next up was the J bar position that we
have not yet sorted choosing to use the shorty panhard
for consistent handling on all track conditions. At
Nelson I used the J bar for the Elf Cup and found a
reasonable set-up but very nervous when the J bar
rolls the car over to the right giving huge side bite.
Every time the car rocked over to the right I kept
thinking about tipping the last car over at last years
Napier champs as the car angle was quite steep and an
unusual feeling. At the Nelson NZ champs this year, I
used the J bar for the qualifying rounds with the same
Elf Cup setup. The car was fast to the point the cars
in front appeared to be going slow but I never felt
comfortable thinking the car was on the point of two
wheeling and became overly cautious deciding to revert
back to the shorty bar for the finals. While not
giving the same side bite, consistent handling allowed
you to concentrate on driving. We will stay with the
shorty bar for the present time until we have time to
trial some different settings with the J bar. I have
my own theories on why the J bar is not consistent and
will deal to this over the off season. The carburetted
415 cube motor has plenty of grunt with 715 hp but I
have to concentrate on pushing the loud pedal to the
floor past where the secondary's open compared to the
injected motor that is very responsive and easy to
give it too much gas. However the upside of the carb
is a softer power delivery especially on a slick black
track like the Glen. I am still learning the best way
to drive this car when its slick but starting to get
the hang of rolling into the corner with no throttle,
quietly on the throttle until the car is straight then
foot down. The gearing has proved to be an important
part with the carby motor due to slower response when
hitting the throttle. There are times when another 100
hp would be nice but that's only on a very heavy
track. Crew chief Rob Jeffcoate is a real petrol head
driving the length of the island for the main
meetings, making changes to rear wheel stagger, wheel
offset, shock pressures and settings, we are slowly
improving the car speed plus seat time for myself, I
should be ready for next season? The car is reasonably
insensitive to small changes and the secret is to make
one big change at a time. For instance moving the
right rear tyre in half an inch is difficult to feel
if better or not. Moving two inches is too much
letting the right tuck under and sliding up so we
settled on one inch for more side bite. From the start
of the race to the end, brake balance is so important
that if not correctly adjusted the car ends up being
either too loose or gets a push and you end up making
chassis changes in the wrong direction. We are getting
closer to a good set-up where the handling remains
constant for a longer period or in a wider envelope.
Shock's are two way adjustable Integra gas front and
rear with a good range of settings. I love the
adjustable gas pressure and found a very good setting
that was not what I thought it should be. Sharing
information amongst other Hypermac owners is
definitely a big plus to finding set-ups quicker and
everyone is helpful to assist where possible. A forth
place in the 30 lapper at the Hoopla was our best
major race to date so far. I particularly enjoyed this
race sitting in behind Ben Harding not able to pull
off the pass, but took time to settle in, adjust the
brakes and work on lines thru the corners on a very
slick black track where sideways doesnt work. Its
been a long time since we were competitive at the Glen
and staying in sight of the winner Ian Burson, was
especially pleasing to me and the crew. Cleaning and
working on the car is a breeze. Powder coating is the
only way to go.
One thing I have noticed with the big car compared to
the wee Nissan is that I dont get pushed around so
much, in fact I can give some back with interest. Our
Elf Super Cup at Dunedin and Cromwell on 2 & 3 March
are the important races coming up then the South
Island Champs at Blenheim two weeks later.
There are 16 drivers in
the Elf Cup this year and the days of 3 or 4 drivers
taking the podium is over with at least 10 guys able
to push for a win. This equates to lots of close
racing and every point counts towards the series so
no-one gives way. First plan is to finish every race
and next is get as many passes as possible to finish
near the front for those points. It aint easy when
every driver has the same idea on tracks where a pass
is almost impossible or you go backwards attempting
the pass. We looked at a North Is versus South Is
Super Saloon teams race with drivers from the two
Island series, at the Glen this year but we have run
out of time and dates so next year we will look to
make this happen.
Cheers
for now.

22/11/11
As of today's date, Ray
has now debuted the new 34t Super Saloon at Woodford
Glen over the weekend. Ray had put a post on Macgors
that read like this:
Hypermac builder Shane McIntyre and father John made
the big pull from Tauranga leaving late Friday night
and arrived at Woodford Glen 4;00pm Saturday
afternoon. I actually arrived 10 minutes later and
everyone had seen the new car before me. Very happy
with what I received, a very professional build and
finish.
Some minor bits to fit, and the car was ready for its
first race. Drove out the pit gate and something
didn't feel right as we gridded up. Stop at the pit
gate for the 3 minute and crew sent me to the
infield.The nut had stripped on the torsion arm clamp
and the arm fell off dropping the chassis on the deck.
Couldn't get it repaired for the second race. Borrowed
a spare arm off my trailer full of spares buddy Burse.
Thanks guys.Start
off the rear not wanting to influence the other
drivers points. Cruise around getting a feel of the
car making some adjustments. This new car handles
differently to last years chassis but not enough laps
to make any real comment.
Found a
new problem, car just barely squeezes into the
trailer.
Next weekend Otago SS champs at Beachlands.
Cheers
34T

Couple of quick pics of the build of the 34t
Hypermac
1/09/11
Its been
awhile between drinks on the web site, with Ray being
exceptionally busy and being unable to do updates for
his web site. Then BAM... all of a sudden an email
comes through with a full update. The site is very
overdue for a redesign and will complete this during
the remainder of the off season which is coming to a
end very quickly. Meanwhile.. enjoy the latest update
form the 34t team.
“Okay okay, I will update the website,” I promised
several followers the other night after lots of name
calling about my pedigree.
In fact the last update was 26/10/10 when the V8 lost
a piston on the dyno.
That was the start to the year when I almost gave up
racing due to an unbelievable run of broken V8 motors
and magnetos and the reason for no updates. Sorry.
Having rebuilt the 377 cube motor with a new set of
pistons after poking a hole in a piston, the motor is
back on the dyno for another run. Recheck everything,
new plugs, change plug leads, sonic clean injectors, ign
timing 34 deg, more fuel, leak down to 24%, to make
sure we don’t have a repeat of the first run, engine
warmed up and sounding sweet at part throttle, lambda
0.76, full throttle run, 4500 rpm and ahh no, she’s a
smoker again. Fuel/air was correct so what the heck
happened. Pull a head and yep a sunken piston crown
with a very small hole thru the top of the piston.
Cant believe it. Okay rebuild motor with extra spare
pistons, do all the checks again, change from the MSD
dizzy and 7AL box to a new magneto. Talk to several
guys looking for why and everyone has a different
theory. Now the motor had been running sweet as during
the season and nothing was different on the dyno apart
from the exhaust pipes.
Do several runs at part throttle checking fueling, all
sweet, ignition 34 deg check.
4500 rpm, POP, ahh shit.
Walk away go home, that’s it I,ve had it.
A month later late November, nothing done, no racing,
pull the motor off the dyno, put it in a box under the
bench and forget it. What now. Buy an older 406 Chev
and drop it in the car with a few mods to fit.
First race for us is the first round of the Elf Super
Cup at Blenheim. Doing the business in the heats,
into the final race, half race and motor goes pop bang
and stops, the car comes to a stop halfway down the
back straight in a poorly lighted area of the track,
most cars get past but then boomfah, Shane Carey ends
up in my boot, tearing off one front corner suspension
and all of his car and I end up with a bent axle,
wrecked gas shock and bars etc etc. Unknown at the
time, the mag had stopped sparking when it got hot and
then restarted after cooling down.
Off to Nelson for the next nights racing, borrow a
diff from John Lovelady thank you very much and all
ready to go with time to spare. Start the motor, all
good. Clean up tools and stuff ready to put car back
into trailer. Start motor and clunk knock knock knock
knock. Ohh Christ what now.
Mick and Smiley have a bet on what that noise is in
the motor. Smiley wins, it was a bent rod after that
cylinder hydraulic’d because the fuel line runs
downhill to the injectors and drains into an open
valve after the fuel tap is turned off. Friggin
dinosaurs. Reroute the fuel line. Back in Dunedin and
pull/strip the motor. Remove the badly bent rod. Mick
Carey finds a replacement for me. Put the motor back
in the car and off to Cromwell for the Xmas meetings.
Mike Verdoner and I have turns about at winning on a
mint track. Third race having passed Mike and bang!!!.
Yup another motor, blew the 406 to bits when a piston
let go. Mike was following and reckon’s it was better
than Guy Fawkes fireworks.
That motor is dead.
Now what. Supposed to be on my way to Napier for the
NZ Champs.
The 377 motor was sitting in a workshop having been
rebuilt once again with a new set of pistons. The
engine man is on holiday still and I have to wait for
3-4 days until he returns. Finally slot the motor in
and off to Beachlands for a test run. Running the
magneto with spark retarded to 30 deg for safe
keeping, car runs like clockwork?? Now what the
!!!!!!!!
Load up and off to Napier. No sleep of course. How
many of us do this stuff, we’re all nuts. We are first
heat up and off the front, not knowing what the car
will do I’m nervous as hell with so many top drivers
right behind me. Didn’t need to worry as we had the
fastest car in that race and even after never ending
yellow’s finished first. At last something was in our
favour. Ooops, spoke too soon.S econd and third heats
we have a bunch of crazy men in our heat and I chose
to just finish not making many placings.
Fourth heat and only need to finish to make the
finals. From the 1st round to the final
round of heats the track got more drivier but we had
tightened the car too much and in 4th place
and passing around turn four the car digs in bicycles
up onto two wheels almost rolling completely over, I
turn right which brings the car crashing back onto all
wheels and slams my spine down onto the seat that
shoots pain up my back and shoulders causing me to
stab the throttle and powers the car forward even
faster crashing into the concrete adding insult to
injury. Finally out of the car I struggle to stand up
and the daughter drives me off to hospital along with
Bruce Boulton with the same injury. About 5;00 am we
leave hospital with nothing broken, a load of pain
killers and into a nice bed.Rob, Rob, Daniel, the
crew, reckon they can get the car repaired so off to
Mark’s workshop where all the McIntyre built cars are
being serviced ready for the finals. The guys work
flat out and manage to throw away about $8000 of
broken bits. Shocks, steering rack, spindles, wheels,
rod ends, bars. No spares left now. My bones are
loosening up and I’m keen to get back in the seat
having to go thru the repecharges. Car is loaded up
all sorted just in time to drive to the track. The
boys put in a marathon effort and I could only watch
as my geriatric body wouldn’t perform correctly. We
are off the second row in the repecharge and quickly
make the passes to second place behind Burse. On a
restart and hard on Ians bumper thinking I still have
a chance to win but not so as Burse powers away from
me and I have no answer having to accept we are not in
the finals. It’s a huge disappointment for us all.
Only bright spot was the motor didn’t hiccup once. We
win the non-qualifiers but that has no meaning when
its not against the guns. The final 3 heats and a one
race final is a great format but there are for and
against. Shane McIntyre 1st, Grant Flynn 2nd,
Richie Taylor 3rd. All these guys deserved
their placing’s which is a change and a good point of
this format. The next rounds of the Elf Super Cup,
Dunedin on the Friday night. We are the fastest car on
a super drivey track that I just love to race on. We
win one heat, gain lots of places in the second, win
the pole shuffle, and leading the final race by a good
margin when that monkey appears again. The motor
starts farting and missing and then we have a fire
underneath that I am informed of with our radio
control earpiece. The motor stops just as I park
myself in a puddle to put out the fire.We don’t finish
and Richie takes the win. Bloody dinosaur magnetos. I
have two mags that have both been rebuilt and checked.
The second mag gets its chance to show how good mags
are, huh. Drive to Cromwell for the Saturday night, do
2 laps in track packing and pull of with another dud
magneto. No racing for us that night. Bloomin hell.
Send both mags off to be sorted. Next race meeting at
Beachlands with Richie and Mike on hand for a good
scratch. I’m off the front and the green flag drops,
the mag stopped right on the start line leaving no
where for Richie and Wayne to go but up my rear end.
Ahh damn, puts Richie out for the rest of the night.
About now I decide to strip the motor and drop the car
off at Mikes workshop to let him pull the motor down
for an inspection as we are running very rich to make
sure the motor doesn’t pop any more pistons. Also the
motor has hung in there with a retarded spark and I
wonder if something else is amiss. Mike strips the
motor and finds the underlying problem. The camshaft
has too much end float that allows the cam to advance
ignition timing to about 40 deg at maximum torque
which causes extreme piston pressures collapsing the
piston crown finally cracking and pokes a hole in the
piston. Motor back in the car, put the MSD ignition
module and box on. Only reason we removed the MSD was
due to the dyno session blowups and blaming the MSD
when in fact it was the excessive cam float. The two
magnetos had caused endless problems throughout and
were tossed in the corner never to be used by me
again. Now the motor started easier, was crisper with
34 deg advance and just ran better. Other mags out
there have ran without problems for years so I just
had a couple of duds. The last two race meetings in
Dunedin and Cromwell helped to make up for the seasons
major disappointments. At Beachlands we set the lap
record and the car is very fast with me finally
getting some race time without motor stoppages.
Cromwell and another lap record on a great surface.
One main difference between the Nissan and Chev is
very noticeable at the end of the straight and entry
into the corner. The Nissan will go into the corner
full tilt passing cars holding a line on entry whereas
if I enter the corner at the same speed as the Nissan
the Chev will wash up and has a greater pendulum
effect. I still don’t have the corner entry sussed yet
but with some more time in the Chev hopefully will get
to grips with speed into the corner. I start to get
some set-ups for the chassis and begin to make some
observations about the 377 cu inch motor. This is a
strong wee engine but the power delivery comes in
higher up the revs than say a 406 or 420 motor and
does not have the torque of the bigger cube motors
that tend to spin the wheels more. The 377 motor is a
good combination with this chassis and ends up a very
good package. At Cromwell I can drive most of the
track foot flat without excessive wheelspin due to
less torque to break traction but good horsepower at
higher revs which gives speed at the end of the
straight. Of course gearing is an important part of
making a smaller motor work to its advantage but the
377 motor builds power progressively allowing the
tyres to grip with less torque at lower revs thru to
high hp at top revs. I wonder if this is a reason
carby motors do perform well on slick tracks with
their smoother delivery of power. Anyway, the end of
the season and I decide to sell the car, advertise on
Macgors and 4 replies in four hours. The first caller
wanted the car complete with motor. At this stage I
was unsure if I would continue racing but a nudge from
the good lady was enough to put my order in for a new
McIntyre car and new motor from the states. The old
car (2 seasons old) now sits in John Roberts shed in
Hamilton. John is a new comer to Supers but has raced
solo bikes so is not totally new to racing. He will
race at Tauranga, Huntly and Auckland so would
appreciate if you can look after him please guys as he
will need a crew. This Friday I’m off to Tauranga for
a seating in the new car to set the pedals at the
right height, Chassis # MKIII/4. If I remember I will
snap a few photos for this webpage.
Any ideas for the new paint job on the new car?
Cheers
Ray
26/10/10 Here's the latest update from Ray and
the new V8 Super Saloon ... I'm hoping to have some
pictures of the car as soon as possible so that we can
change things around a little on the web site. But for
now.. grab ya coffee, pull up a chair, and check out
what's been happening with the NEW 34t car...
Jeez, its that time already.
The first of October signals the end of the off season
with practices underway at most tracks. The Nissan is
parked in a lonely shed still requiring repairs from
its last race but time and a V8 to prepare means the
Nissan will stay that way for some time yet.
The
last two months have flown by and caught me out not
ready for the seasons start. The Chev is on blocks in
the shed mostly finished with some minor finishing
required to the chassis and rear suspension
adjustment. After racing the V8 for just two meetings
at the end of last season I found some minor
alterations that would suit me better and make the car
easier to alter during a race to stay on pace. A good
weight jacker can make the difference when a track
goes dry and loose which is the case with a big field
of cars racing over 20 laps or more. Even more
important than a weight jacker is brake control and
balance. Its amazing how many drivers don’t take this
into account or even know what to do during a race to
keep the car straight into a corner on a slick track.
Both front and rear right side brakes are used to
balance the braking or transfer more brakes to the
front as the track goes away. The car has adjustable
Integra shocks front and rear that are so simple to
alter and you can definitely feel the chassis working
on any type of track. I was impressed when altering
the front rebound setting, the car transferred weight
to the rear smoothly allowing the car to hook up off
the corner without wheel spin. Now normally we change
the shock rebound and compression as the track
slickens off but I found on one corner shock what most
crew sets the shock
at, the opposite was in fact much better and thinking
this thru it makes sense. Bet you cant figure that one
out. The original body will suffice for the start of
the season until I get the time to prep and paint the
new panels sitting in the shed. I like the shape of
the C6 Chev and will retain the colour scheme also
that is very similar to Shayne’s new car and both look
smart. So the chassis is more or less ready to rumble
which leaves that bloody dinosaur V8 to sort out. Does
that tell you something. The Turbo Shop in Dunedin
owned by a true petrol head Mike Lynn, has a Super
flow 901 engine dyno that is invaluable for tuning and
a must do on any new motor. After spending thousands
of dollars on all the good bits to build a race motor,
if you don’t dyno the motor you're a fool and have
probably left all your hard earned money still sitting
in the motor waiting to be let out. Fine tuning can
increase the hp by sizeable amounts in the hands of a
good operator. It is so much easier to find all your
problems on the dyno rather than waste time and
weekends of racing and DNF’s. You won’t believe how
true this is and very seldom do you get a trouble free
run on the dyno that would have materialized on the
track.
Also
interesting some of the horsepower figures being
passed around for certain motors. Between dyno’s there
maybe a difference of 100 hp or more for the same
motor. What matters are the gains made in hp on the
motor on that same dyno. Six weeks ago we put the V8
engine back on the dyno to finish the fueling and play
with exhaust pipes plus intake trumpets. Over fueling
while idling and part throttle meant too much methanol
was wasted and the engine never getting up to
temperature. Give me an EFI any day, so much pissing
around with the Kinsler mechanical injection that you
can only achieve a compromise in several areas of the
rev range. We use a digital lambda which gives an
immediate read-out of the fuel/air mixture and is
compulsory for tuning to save time. Under full
throttle in the mid-range, the torque curve has two
distinctive droops in the torque curve that we could
not tune out due to too much fuel in those areas but
the remainder of the fuel curve is okay. Those rich
portions are probably worth 30 ft/lbs torque and that
is significant for a 370 cu inch motor. An EFI would
get the fuel spot-on right thru the rev range. Maybe
later. Some time was lost playing with different pill
sizes, springs and pressures but the changes didn’t
make any noticeable difference. Start at the
beginning, check the
leak down of the main metering unit, ah ha, over 50%
leak down, now how the hell did that happen. Set the
leak down to 17% and do a dyno pull, now we are on the
right track but still lean. Re-set leak down to 22%,
and dyno, yep, the motor idles and runs sweet at part
throttle like it should. Altering the pill sizes gives
immediate results with the leak down correct for this
motor. The engine is showing the correct lambda right
up to 7500 rpm so we start to pull some full dyno runs
at full throttle. With the correct fueling we gained
30 hp. Settling on the final pill sizes and by pass,
we change from 8 injectors to 16 injectors. Another
impressive gain at top end showing good horsepower
with more revs. This is one strong wee motor
originally built for Tony Cardwell 7 or so years ago.
The exhaust pipes on the dyno are off a sprint car and
only used to clear the dyno frame etc and will be
changed to the proper pipes as part of the dyno
program. During one of the dyno pulls, a pipe used to
divert the exhaust gasses to the main dump pipe falls
off and we lose
power??
Put the pipe back on and sure enough the dyno didn’t
lie. We lose/gain 40 hp from a pipe change by
mistake. Some research into why, explains the
reasoning and 2 new pipes to be made to try in a few
days. A V8 has an odd firing sequence with the exhaust
pulses giving uneven pressure waves back at the
cylinder and a loss of torque unless a 180 deg exhaust
is used which is messy to build and fit. The pipes
used in the car are fitted to the motor back to front
so they miss the dyno frame. A quick pull and oops,
smoke out of one of the injector stacks. Bugger, strip
the heads off the motor and we have cracked pistons,
one has a hole. What caused the hole?? Blocked
injector or injector hose, blown gasket, ignition,
don’t know yet. Remove the motor and give to the
motor rebuild man. Order a new set of JE oversize
pistons from the good old USA. Now we wait until the
motor is back together before back onto the dyno. I
don’t see the car being ready now until the end of
October or even November. Give me a FJ20 motor any
day, overhead cams instead of those compromised push
rod and rocker arrangements, 4 small valves in place
of 2 huge discs of steel that don’t pass as much air
anyway. 4 pots much quicker to strip compared to an 8.
Mechanical injection yuk.
Yep these are dinosaurs for sure!!!

7/4/10 Its
seems like an eternity since I sat down to do an
update on this web site. But here we go again with the
latest scribe from the pilot of the 34t car. But now
there is a twist to the Ray Stewart story that caught
many out by surprise, so lets see what Ray has to say
in this update. Before then though, my apologise for
the last update which was very hard to read
considering half the sentences were missing. This has
now been fixed. So sit back, grab yourself a coffee
and read the latest news from Ray Stewart:
Easter week-end
past and almost the end of the season. Since my last
scribe for the website, several things have changed
hopefully for the better. Its all a blurr really the
last two months, the South Island Champs at the Glen
was a mid-field finish on a very slick track that
Trevor Elliott won for his first S.I. title. Two weeks
later and the 3rd round of the Elf Super
Cup also at the Glen and we finish consistently in the
front 5-6 cars with an overall 5th place
for the round and move up to 7th after 3
rounds. An improvement but still lacking speed to be
at the front and off the pace we had 3 years ago. Mike
Verdoner keeps Ritchie behind him to take the win but
Ritchie still maintains a good points lead over
everyone at this stage.
On the 5 hour
trip back home after the racing I get to thinking
about the changes we have made and the results have
been dismal for about three years since we changed to
the torsion bar suspension.About the same time a text
from crew man Rob Jeffcoate and the same thought if
the 4 link was worth looking at again. I changed from
our 4 link coil over to the torsions in the quest for
some side bite but in fact had gone backwards. I
understood a whole lot more now and the reasons for
the torsions failing to work on this car where they
are very successful on most chassis’s. It revolved
around chassis height, roll centre and centre of
gravity. When building the torsion rack into the rear
end of the Nissan, the torsion rack height was set-up
the same as in other cars which turned out to be too
low in the Nissan chassis. With too much roll-over or
two wheeling we had the chassis height too high when
the torsion arms were level. Once we figured this out
and dropped the chassis height down one inch, then the
torsion arms were facing uphill and defeated any
advantage. I would have thought the higher chassis
height would be an advantage but it shows just how
critical roll centres are in conjunction with C.O.G
and the type of springing utilized, torsions with low
spring base versus coil overs mounted higher in the
chassis to support the car.
Back in the shed ,
I had saved all the 4 link components and it was
reasonably quick to fit back into the car with only a
few brackets to remake. Now which lateral link to use,
Jacobs Ladder, Panhard or J bar. Off to Island Park
with Wayne Andrews turbo XR6 for a day of testing on a
slick track. The tyre stagger, pressure, springs
remain the same and we only change the bars for a
comparison. Very quickly we have an answer what works
best for side bite and forward bite and will keep this
to ourselves for the present. The one minor change
from our 4 link set-up from 3 years ago was to raise
the chassis height half an inch and this alone made a
huge difference on a slick track. It become apparent
also that the 4 link suspension in my opinion, was the
best rear suspension to use on a super saloon New
Zealand style, allowing infinite tuning with
mechanical effect on forward and side weight transfer.
The links angled upwards to push the rear axle under
the car, tuneable rear steer by altering the length
and angles of the 4 bars facing forward plus
shock/spring location for birdcage indexing combined
with the lateral moving axle for side bite. I cant
believe we wasted 3 years to figure it out.
What better
place to prove all this theory than the NZ GP at
Island Park on Friday night and teams racing on
Saturday March 15th.
1NZ, 2NZ, 3NZ,
4NZ, all turn up for the double header on a real lousy
wet cold Friday but a superb graded track for three
car wide racing right up to the concrete.
We have a car
again that handles but need a few races to sort the
stagger, pressure and roll centre height. Come the GP
final start and Steve Flynn on two, gets it sideways
across the track leaving nowhere for the following
field to evade a major pile-up that sends 5-6 cars to
the infield including Brent Emmerson, Richie Taylor,
Trevor Elliott. What a blow for so many of the top
cars to be out in the first corner of the race.
From the
re-start the Nissan is on the pace making some outside
passes and sitting in 5th at the first
yellow light behind Burson, Boulton, Williams,
McIntyre. At last we can stay with the best but a
little further into the race making an outside pass on
a lapped car, I get wide in turn 3, turn myself around
and to the rear of the field I go for causing the
yellow.
Burs goes on to
win the GP from Boulton and McIntyre.
Saturday night
for the first ever super saloon teams racing between
the provinces with 7 teams competing. Shane Maaka
pulled the event together with the Island Park
committee that gained interest from the drivers with
team tactics resulting in some interesting racing.
The top 5 teams
went to the final after racing thru a pool of knock
out races.
Our team,
Central Otago ended up in the final chance to move to
the final after 4 races that gave us the opportunity
to fine tune 34T to a race track gone slick but
rubbered up and still very fast. We are off grid 10
and quickly make passes up to 6th place,
the Nissan looking for passes on the outside line.
Black as I have seen any track, rubbered by powerfull
cars laying rubber but amazingly still able to make
passes two wide anywhere around the track. Another
lapped car to pass but too fast into the corner,
turning 180 degrees again. Damn I was really enjoying
the drive making small adjustments to brakes from the
cockpit and racing alongside cars that previously
would leave me behind.
The change back
to the 4 link combined with the bar set-up and raising
the chassis height gave us a car that was even better
than our original 4 link arrangement. Too late in the
season unfortunately.
A week later and
off we go to the final two rounds of the Elf Super Cup
at Blenheim and Nelson. Friday night Blenheim in front
of a full house the Nissan is on song for the first
race passing Elliott and Verdoner on the outside to
take the win easily. Havent done that for a long time
and gaining confidence in the car. The 25 lap final
slicked out and Richie and the Nissan raced side by
side for over 10 laps until the outside line finally
gave out and I drifted back not able to find any grip
but more than pleased with our effort.
A quick
mid-night trip over the hill to Nelson for the
Saturday night final of the Elf series but an early
morning start to fit a new head gasket. Nelson had
been a good track for the Nissan in past years but
with so many cars going fast, the outside passing was
a thing of the past as this is a very fast momentum
track with no room for mistakes and in the second race
of the night the steering wheel of Dave Walsh came off
and he piled into turn one at full speed on the first
lap wrecking his car against the wall coming to a stop
on the wall but we are full on into the corner not
sighting Dave until the last split second crashing
side-on into the left rear wrecking the right side
roll cage and tubes. That’s it for us as it was for
Taylor and Verdoner in the first race leaving the
overall series win open to Josh Boulton if he could
finish the 25 lap final better than 6th
place. For a while it looked like Taylor would retain
his
points lead but eventually cars in
front of Boulton spun out or become tangled allowing
Josh to move into 5th place for the Elf
Super Cup series win.
Car 34T ended up
9th overall after 5 DNF’s from other cars
crashing and a broken drive shaft.
And FINALLY,
During the last
2 months I had been in contact with 2NZ Shane McIntyre
regarding the possible purchase of his car. Earlier
Shane had broken his motor and my 360 cu inch V8 motor
had just come off the dyno from adjusting the Kinsler
injection, so box it up and off to Tauranga goes the
ex TC motor to sit in the 2NZ car. Since then Shane
has punted the small motor to great effect and finally
a deal was struck to buy the car. Shane finished the
SSCAR series at Wellington taking out the overall win
and crossed the ditch the next day to bring the car to
Cromwell for the Easter races where I took over the
car.
Forget about
keeping a secret, one word and everyone knows within
hours as texts and phone calls start quizzing about
what's up and me buying a Jurassic race car.
Friday we set
about raising the seat height to suit my smaller frame
and I get familiar with the car lay-out. What a
beautifully built car. I made a good choice.
Crew chief Rob,
drives down from Nelson to get to grips with the new
car and Saturday we all scoot up to Wanaka for the
Warbirds over Wanaka. The neck gets a good workout
looking skyward for most of the day. If you haven’t
seen the show take the opportunity at some stage as it
is worthwhile and a mate reckoned the air show is far
superior to the European displays of aerobatics.
First night at
Cromwell is rained off but a beautiful day following
and my first run in the EX 2NZ car. Apprehensively we
are off not wanting to ding it in my first outing and
immediately understand my Nissan is a totally
different car to any of the V8’s. 700 hp in a small
chassis must have some downside. I liken it to
controlling several nervous kids on steroids against
sitting in a recliner chair with feet up. The McIntyre
car is smooth and easy to drive, throttle control is a
breeze compared to the boosted 4 cylinder, no
twitching or feeling every bump in the track,
definitely a wider longer bigger feel. The Nissan has
to be driven at 100% all the time whereas the Chev 80%
will get you there. Its almost too easy but it will
take some time to gain confidence and barrel into a
corner on full song to keep up with the top drivers.
The second day is a 12 o’clock start but a good
opportunity to experiment with set-up on a slick
track. After 3 races I begin to get a better feel of
the new car and Shane has made changes for side and
forward bite which see the car rocking over and
bouncing the front left wheel. We learn another
valuable set-up for slick tracks. Wow, this is neat
the car hangs in there rocketing off the corner
putting the power down. I will need to change my
driving style to suit the bigger car that is more
stable on all types of tracks.
The small 360
cube has more than enough zap at Cromwell which suits
big engines so not looking at changing that yet. That
big box in front housing the injectors does limit the
view and will certainly need some slimming.
And the Nissan?
Well its still a very fast car especially now we
finally have the handling sorted. I’m still annoyed
with the loss of those 3 years.
The crew and I
have enjoyed 6-7 years of success with this potent
little weapon but we do know good things come to an
end. We haven’t been fortunate to take the 1NZ but did
get close on 3 occasions when the car was the fastest
on the track and a little luck might have seen us get
there. Over the years we have held numerous lap
records, a few still stand but some never recognized,
an outsider maybe?
Most memorable races: winning the GP at
Waikaraka Park, the two lap shootout against Dean
Waddell at Cromwell, Canterbury champs sent to the
back and passing everyone to take the lead, just a few
of many.
I know there are
a lot of fans out there who have followed the results
over the years, mostly because it is different from
the V8 boys but also the smaller car has been the
underdog kicking V8 backsides on plenty of occasions.
I remember several times during or after a meeting
being surrounded by onlookers in the pits inquiring
about the amount of horsepower, what motor, must be
very light etc, especially after winning against the
bigger cars. Even recently the wee car gets punted by
the big boys bowling us off the track as they know we
can be moved, but now its my turn.
Over the years
all the guys who have worked on the car did so because
this was not a V8 and were as involved in the success
as myself, Rob ,
Alex (Mango), Elliott (Prozac),
Kerry (Magpie), son Daniel,
my wife Gail and daughter Rebecca
are my biggest fans next to the Nelson Bowen clan.
Those times when
we beat the V8’s and hearing the comments from driver
and crew “That f.…n Nissan”. That was very pleasing.
I do feel
annoyed that I have finally taken the V8 plunge but 13
years with the Nissan I think I have proved a point
and time to move on while I have a few years remaining
in the sport.
What will happen
to the Nissan? the car will be repaired correctly to
its former glory with new panels etc and probably sold
without the motor as it seems the FJ20 is a little too
complicated for most people to maintain.
I am sorry that
the Nissan will probably not be raced again as a 200SX
FJ20 Hybrid and will end an era of something different
to compete against the V8’s.
Some have
suggested restore the car and become a coffee table?
Its unique so preserve it? I believe someone will
take the car minus motor and install either another
Jappa motor with less complicated horsepower or a 350
cube V8 would be a real weapon.
Thank you to all
those who have followed our progress with genuine
interest thru the years. I had plenty of PM’s thru
Macgors congratulating us on our success. The 34T crew
and myself did enjoy the many questions and I will
miss this side of the Nissan as we are now in just
another V8 but hopefully a winning one.
Thanks Jase for
setting up this website for the Nissan. I know your
interest was in this car because it was out of the
ordinary and now I have spoiled that cause.
You can get to
drive the Nissan, just buy it.
Cheers
Ray Stewart
Brilliant write up there Ray. Personally I think the
web site should be archived and left in an area within
the web site for people to look at. As for the way it
heads from here, well, it would be wrong to shut her
down. Pretty sure the heading up the top says Ray
Stewart Racing, regardless of what car you drive. My
biggest concern was that you were going to get out of
racing completely. That has now been addressed and so
its onwards and upwards from here. Once I have some
pictures, the web site will be changed and altered to
suit the next wave in the racing life of Ray Stewart.
6/1/10 Ok...we know...its been awhile between
updates, but as many know, Ray has been very busy
along with myself as well. But the good thing about it
is that when you get an update you know its going to
be very detailed. Ray hasn't had the best of runs as
of late, and this is starting to take its toll on the
enthusiasm of Rays racing. Its safe to say that
speedway is still floating through the veins of the
34t pilot, but the car itself just doesn't want to do
what its supposed to. But anyway.. here goes the
latest update from Ray:
Cripes, its 2010 and 4 months since my last report.
Jase has been on my case to update with some news as a
number of people have emailed him requesting an update
so Jase threatened me with letting him drive 34T if I
don’t get my act together. No-way will I let him drive
the car, I can prang it with-out his help. Maybe one
day just after Ive sold the car. My business keeps me
very busy and consequently we have not put the number
of meetings in as usual. Most seasons we travel to
28-30 race meetings but I think this year will manage
only 15-18. The downside to limited races is having
race time in the car to get a set-up and confidence in
what the car will do. We continue to struggle for a
slick track set-up and I have no confidence in how the
car will hook-up in a corner. Interesting when
comparing the North and South island tracks. Most
would say the Northern tracks would be slick and the
South drivey, its actually the opposite in most cases.
Woodford Glen, Island Park, Blenheim can be guaranteed
to end up with smooth slick black clay where
horsepower is not the answer and a limited saloon will
match the Supers. The 25-30 lap feature race at the
Champion of Champions at the Glen, is usually won by a
local car on the black slick surface and the North
Island cars struggle to match the speed, not used to
racing on slick tracks. Waikaraka, Huntly, Baypark
normally are good drivey tracks. There are many
reasons why which I wont get into as this might start
world war 3. Needless to say Cromwell and Greenstone
Park are my favorites in the south that the Nissan can
show off its speed. However the feature race is at the
end of the night and the money is in the slick at
most tracks in the south and that’s where we continue
to fall short with the power delivery of the FJ20
motor too aggressive to hook-up. Over the last few
years, we have changed to several different rear
suspension arrangements in the quest for side and
forward bite but with no great improvement which comes
back to the power delivery. So what to do? The season
to date is one I would rather forget. The Champions 2
night meeting at Woodford Glen was a disaster. First
race on friday night we won, but back in the pits the
over temperature light came on. End of racing that
night, the head gasket not sealing correctly so off
with the head in the pits during racing to check out
the problem. We use a certain brand of RTV sealant on
the head but this time had used another brand which
dried off too soon and increased the thickness of the
head gasket by a few thou so when pulling down the
head, the ‘W’ rings did not push far enough into the
head for a proper seal. An easy fix as the head gasket
was perfect and the next day we would find the correct
RTV, reassemble and whalla, ready for racing again.
Yep went together easy-as but unknown at the time
someone messed up. Saturday night and we managed to
sneak thru to the final with two third placings. The
car did not seem to perform as usual but couldn’t put
my finger on it. A great thing with the Champions
format, you can watch other heats racing. Richie
Taylor, Shane McIntyre, Ian Burson were fast all night
and I reckoned these guys the top 3. As expected the
final was a slick black track that suited the local
cars although we managed to circulate at reasonable
speed but not up to the front cars. Ritchie, Shane and
Kane Lawson, one two and three. Very impressive of
Kane in his first year of Supers to take out third
place. Friday night December 4th, the first round of
the ELF Super Cup at Island Park. During the off
season numerous emails and phone calls to all the
drivers who entered the Elf Super Cup to keep them
informed of the progress plus what and where so
everyone understood exactly what was expected of them
on the night. 18 drivers entered the series, a good
size field for all the tracks. At the pre-race drivers
brief with the crews also included, the radio sets
were handed out to the drivers and instructed on how
the nights racing was to operate. A heavy track to
start for the timed lap with a 3rd fastest for 34T.
Mmmm, the car should be a rocket on this track but
seemed sluggish. Onto the final race and we are
starting mid-field from not so good heat races. 3 laps
into the final and Kane Lawson gets hooked up with
another car causing a 6 car pile up that I couldn’t
dodge smashing into the rear of Denis Bolt wrecking
his diff, destroying our front right suspension and my
hand caught in the steering wheel wrenching my
shoulder, elbow, wrist to the side which felt like I
had popped the arm out of its joint. Jeeze takes a
longer time to heal as you get older. So sitting on
the infield watching, 4 cars scratching for the win,
Burse sitting on the outside of Richie for the last
4-5 laps and side by side on the checkered with
Ritchie getting the win. What a fabulous race to
watch. The best thing about this type of format is the
top cars are at the front for the final race instead
of spread out down the field. The following Saturday
night Dec 5th at Cromwell for the second round of the
Elf Super Cup but minus Denis without a spare diff, we
had this covered and Owen Dixon was included to
maintain the 18 car field. In our negotiating with the
tracks for the Elf series, there was concern that the
drivers would not do all the rounds if they were out
of the running. However the drivers were made aware
that it was imperative to attend all rounds as we had
guaranteed the tracks a minimum of 16 cars otherwise
$$ would be deducted from appearance money so we have
cars to fill-in whenever a car dropped out. Another
drivey track for the timed lap, I consider Cromwell as
one of the fastest tracks in NZ where you are on the
gas for 80% of the time but the car wasn’t hauling
like it should and 3rd fastest again. For the first
heat we were 3rd and try as I did could not get past
Ron Taylor, again foot flat and not performing. In the
last lap of the first heat there was a bad vibration
in the drive line and I eased off a snatch and dropped
down to the pole line to hold my position for the last
lap. A few metres before the finish line the
driveshaft let go, unknown to me Ritchie was right on
my bumper but moved up away from the pole when he saw
me drop down to the pole line thinking something was
up and just missed punting me in the rear. The problem
was the torque arm had collapsed resulting in the arm
rubbing against the drive shaft, wearing a groove
which finally twisted off the driveshaft. Not able to
repair the torque arm I sat down to watch the racing.
For each nights final race, the cars do the 4 wide
salute and looked very professional as though by magic
they went into 4 wide then back to 2 wide. Our radio
man Flash, has one way communication with all the
drivers and instructs them on what and when. It’s a
great system and if there is a crash a quick “crash
turn 3” warns all to be on the look-out and possibly
save cars rear-ending each other. Ritchie had the
set-up and took line honours from Josh Boulton and
Trevor Elliot and the overall series points are the
same three. As the co-ordinator of the Elf Super Cup,
I am impressed with the attitude and approach from
drivers, crew and everyone involved with the series,
very professional and they want the series to be a
success. At the first round in Dunedin there was some
apprehension but by Cromwell it was evident the
drivers plus all their support crew were enjoying the
racing and with the next round at the Glen on Feb 27th
it will take some effort to haul Richie back. However
it only takes one bad run to allow others to overtake
him as the points are close.
To
check on the Elf points go to the Elf website;
http://www.supersaloons.co.nz/
Thinking back on the two rounds of the series and why
the car did not perform as it should do on drivey
tracks, it could only be we had re-assembled the motor
at the Champions with a tooth out in the cam timing.
Remove the cam cover, set the dial gauge and degree
wheel and yes one tooth out. Probably 100-150 hp down.
Now who marked the cams when stripping it down, wasn’t
me and I’m sticking to it. With xmas approaching, time
for one more meeting at Island Park in the search for
a slick set-up. We have stuck with the panhard bar
mounted on the right side of the chassis so played
with chassis height, stagger and weight in different
positions. The right side panhard gives side-bite and
we were two wheeling on numerous occasions but this is
not fast having to back out of the throttle which is
slow. From not enough to too much, heck it’s black
magic. Off to Auckland before the champs and the
opportunity to have a run at Huntly on the 31st Dec.
That 2 wheeling back again. Back to a heavier right
torsion bar, some turns in the front right spring,
weight in the rear and its at least manageable. Friday
night NZ Champs, Huntly, a new race format, 30 top
cars, drama straight off in scrutineering, 3 top South
Island cars are not allowed to run as we have illegal
wheels with lightening holes too close to the
bolts/studs? Now a rule is a rule and as I was one of
those breaking the rule we thought that was that. The
wheels have been in use on our cars for years, stamped
each year and green sheeted without problems plus
hundreds of scrutineering without knowing the wheels
were illegal. Now the Huntly crew did not want to see
3 South Is cars excluded and worked away at finding a
solution and to their credit called all the drivers
into a meeting explaining the hick-up of the wheels.
The deal was every driver had to agree to our racing
and if one disagreed, we were out of the champs. After
some discussion one driver got it right by saying
“does anyone here not approve to these cars racing” no
one spoke up, end of story and we are racing. Three
groups, four heats each, we are first up rear grid,
lots of stagger for a heavy track? nope, driving onto
the track and its as dry as a bone, ahhhhh damn lots
of wheelspin and no passing for 34T, finish 8th.
Watching the other heats gave an indication of who
were the fast cars with 7-8 on pace to win. Richie
Taylor blew his motor in his first heat. Our second
heat off the front with the right stagger plus a few
minor changes. One of the crew growled at me to pull
finger, okay I get the hole shot and off we go car
feeling nice, 4-5 laps we have a good lead then down
the back straight into a blinding sun and I see a
yellow light at the other end so slow up, in the
shadows and it’s a green light not yellow, a car is
inside me so on the gas into turn one a little higher
up the track, turn in hit the throttle and oooh shit,
backwards into the concrete completely destroying the
rear end, fuel tank separated and blowing fuel
everywhere, then the roll over ending upside down.
About now it became scary hanging upside down in my
belts when methanol and oil began to drip into my
helmet. I had turned off the power switch but the
thought of fire was there especially with fuel in my
helmet. Release the belts and fall onto my head, try
to crawl out the window but my new fully contained
seat obstructs my exit and now I’m becoming anxious.
The track crew are there immediately and I tell the
guy I cant get out so he begins pushing and pulling
but it takes 30 seconds to finally crawl free. Walking
away from the wreck, I notice the track is very greasy
right where I slid up the track and gassing it up only
made the car slide faster into the wall. Watching the
replay later I noticed Red the promoter, moving the
other cars away from the crash as there was methanol
running down the track and I thought about the flames
off their exhaust when idling, thanks Red. The roll
cage and 5 link seat belts do their job and I have
only a small cut to my forehead but of course I’m
really pissed with myself. That night we strip the car
to have a shot at repairing but give up at 3 o’clock
with too much damage to undo. The roll cage has
compressed and the rear end and fuel tank need
rebuilt. Oh well back to watching. The finals night
was the best racing I have seen in Super Saloons
anywhere with three heats and top points to the front.
Several of the top cars had a bad heat but still were
close enough to the front to be in the running. The 20
lap final was a beauty, Steve Williams, Brent Emmerson,
Shane McIntyre, Mike Verdoner all looking for the pass
with Lance Jennings, Denis Bolt, Ben Harding right
there but further down the placing Pete Hemi drove
from the back of the field on the outside line passing
cars every lap and getting closer to the front cars.
Steve Williams got himself sideways and Emmerson and
McIntytre crashed into Williams stopping the race.
Unfortunately Williams had a flat right front tyre and
was out. The restart continued the exciting race and
all eyes were on Hemi coming up quickly to the front
runners, 5 cars in the front group so close anything
could happen and did. Hemi had caught up and went for
the outside pass, got around Verdoner and almost
Jennings but both become bumper tied and on the
infield with two laps to go and no stoppage, while
during this action Emmerson had pulled an outside pass
on McIntyre and held the lead to the finish and 1NZ.
Fabulous racing made possible by the drivers and a
format that allowed the fastest cars to start together
off the front. I hated watching but this was a good
alternative. The Huntly team had pulled off the best
Super Saloon Champs yet and done their best to keep
the drivers in the racing. Back home wash my poor
wrecked car, park it in the shed and sulk for a week.
The next meeting in one week so time to look at the
car again and Steve drops in to help out. A major
rebuild of the rear end, new fuel tank, new roll cage,
2 bumpers, and so on. 4 nights past midnight, Friday
and almost done. Saturday everything in place at 2:00
pm and Steve leaves to help out at Island Park. I’ll
be right I say, start the car and it goes then coughs
and wont restart, mmm sounded like fuel, fuel on in
cockpit and at the tank, remove one of the fuel lines
and no fuel, back to the fuel tank valve, no fuel, I
already know what it is. Our fuel tank builder had
welded on the nipple outlet but forgot to drill a hole
for the fuel to flow out. Ten minutes to find the
problem and 2 hours to fix it. Finally start the motor
but running like a pig. Check the injectors, spark and
all is okay. Damn it, load up and off to the track,
maybe will come right. 6:00 start and I arrive at
6:30. On the track and the motor clears almost
immediately. An air lock needed some pressure to
clear. We have the Jacobs ladder installed as I know
what to expect. The track goes as black as the ace of
spades, shocks, stagger and tyre pressure with a big
lump of lead help the car but not enough as Josh
Boulton takes out the Otago and South Pacific GP. Some
track testing required to settle on a set-up and
hopefully in the next week before some big meetings.At
least the car is going again. Two weeks before the
South Island champs and then the next round of the Elf
Cup.
I
promise Jase I will get a report to you earlier. Its
past midnight and finished this report so no way you
get to drive 34T.
Cheers all.

Rumour has it that Ray is
looking to sell the car. This was confirmed when it
appeared on MacGors, with Ray testing the waters to
see if there would be any bites would come of it. Keep
an eye on this site to find out what his next move is.
Ray attended Island Parks
first meeting in Dunedin, to give the car a run before
the pending NZ Grand Prix. Ray was saying that the car
failed to perform due to a miss in the engine that
wouldn't go away. The car hooked up well in practice at
Cromwell, but would not carry on through to Dunedins
meeting. Rumour has it, that Ray then went on to
compete in Christchurch this weekend just gone, and
the car was very quick. I hope that Ray can give us an
update on the ins and outs of that. Meanwhile, here is
the latest scribe from Ray that was sent through about
a month ago. My apologise for the late update, but had
a major failure on my server that was storing the
update until I got round to putting it up. Here's what
he had to say:
One month before practises begin and the Nissan is
spread around the workshop but should be bolted
back
together by the end of September. Like alot of
speedway drivers, the car sat in the shed untouched
for months and I didn't get started stripping the car
out until mid July and have limited most of the
off-season repairs to an engine fresh-up plus minor
chassis mods. The FJ20 motor was in good nick when
dismantled and didn't really require new bearings etc
but if you don't then who knows what will happen. So
new rings and bearings, new cam chains, crack testing
the crank and rods, very light hone of the bore's,
send the pistons away for re-slip coating, head
stripped and 2-3 thou off the head to give the special
sealing rings new material to bite into to help
contain the 25+ pounds boost. Lap the valves in, check
the valve spring bind and set the valve clearance. It
takes 30 odd hours to rebuild the head to get the
power and reliability required for a seasons racing.
Reassemble the block checking the crank runs free as
the main bolts are torqued down. Oops, number 3 main
is grabbing, remove the bearing shell and there is a
burr on one edge, scrape it off and try again.
Perfect. Now one
of the main problems with this motor was head sealing,
containing all the boost in the cylinders, so great
care is taken with the stainless steel 'W' rings that
are recessed into the block and the modified head
gasket glued in place before carefully pulling down
the head. Last season we changed the normal head bolt
system to ARP studs with fine threads that have really
helped hold the head on and limited any leakage
although water seeps out until the engine is warmed up
and expands giving the final sealing.
Dialing in the camshafts requires a clear head and the
radio turned off so I don't cock-up the numbers.
Several years ago after trying several camshafts from
overseas and in NZ that had no low end torque and were
made for engines with gearboxes, we designed our own
cams and on the dyno found the best lobe centre
combinations that pumped out strong torque at low
revs. A difference of 5-8 degrees in LC would drop the
torque 60ft/lbs at 3500 rpm so it was important to get
the timing spot on. It seems every time the engine is
stripped down the timing alters due to very minor
changes in head machining
or
the bottom sprocket is in a different position. Over
the years I have accumulated a number of top
sprockets with different spigot holes that give
different cam timing but it still takes two nights to
get the timing where I want it. A new triple plate
clutch pack on the one of its kind flywheel and the
engine is finished ready to slot into the chassis. The
bell housing was totalled at the NZ champs when it
flew apart at 8500 rpm but we had to piece it back
together as nothing else was available at the time.
When racing in the north island last season, Prozac
and I met Mark in Napier who was building lots of
parts for speedway cars which included bellhousings so
we sent off the rehashed housing to be copied. This
arrived a few days ago and it's a piece of art. It is
a totally professional finished article that fitted
exactly in place and a pleasure to receive something
that does not need any modifying or hacking to fit.
Tuesday 18th Aug and the motor is bolted in the car.
Over the next week every thing should be in its place
and ready to start. Now to decide what to do with the
body, same as before or go to the wedge shaped Late
Model US style body. The specs for the wedge shape is
still in limbo with SNZ and no
sense to alter the shape yet so perhaps during the
season we will see a new body.
Last month 25 super saloon drivers assembled at Bolts
motor camp in Christchurch for the sole purpose of
putting in place the commitment from the drivers to
push forward for running the south island Super Saloon
Series. There was full support from all those
attending with a hands up from 21 drivers who would
commit to the series. Taking into account those who
will have other commitments, we expect about 18-19
drivers for the series. Much discussion regarding the
number of meetings came up with an ideal plan to hold
double header meetings on the same weekend to save the
long hauls for those from Nelson/Marlbourgh and Otago/Southland.
Friday night at Blenheim and the following night at
Nelson, two meetings for the travel of one.
After much hair pulling and emailing, we have finally
nailed down dates to hold 5 rounds for the series as
follows;
Island
Park, Friday 4th Dec
Cromwell, Sat 5th Dec
Woodford Glen Sat 27th Feb
Blenheim Friday 26th March
Nelson (Final) Sat 27th March
ELF Lubricants are our named sponsor for the series
and we welcome them on board to add that extra
professional approach from a worldwide known brand. We
want to raise the level of the Supers class for both
drivers and spectators but also for the tracks putting
on the meeting. A more professional approach to the
sport is required by the drivers if we expect to raise
the profile and to put on a show that gets the fans
applauding our racing.

A new website is underway for the fans to follow the
progress of their favourite driver. The website will
be advised later. I have just learned that SNZ have
discussed stopping all of the series being
run at present, DHL, Midget Series, Stocky's, SSCAR
etc. Some excuse about fidelity fund. If SNZ tried to
pull a stunt like stopping all of the series, I bet
they would lose a huge number of drivers. I for one
would give the one finger salute and the majority of
guys I know would do the same. SNZ and SPANZ do
absolutely nothing to promote speedway in NZ and the
drivers have taken it on themselves to promote and
strengthen their class by creating their own race
series to attract more drivers and preserve the class.
Watch this space.
The phones ringing so until next write-up keep us in
mind.
30/6/09 Busy busy
people, is the best way describe the team from Ray
Stewart Racing. Its the old story though, the updates
might not happen over night, but they will happen.
Here goes the latest chitty chat from the pilot of the
34t car, with all the racing from the North Island, NZ
Title and Grand Prix. Sit back and enjoy...
Almost July and another plead from
Jason to give an update for the site. Sorry all for
not keeping you up to date. Just too much happening
during the last 6 months to sit down and give a full
report of where we got to with the season.
The last report had us racing in the North Island
series after no series eventuated in the South Island
and the opportunity to race in the north. Well it was
to be our poorest season ever with a car that just
didn't want to hook up on any track. Some of our best
tracks, Waikaraka, Gisbourne, Huntly, Baypark, Te
Marua, Napier, were to be nothing much better than
mid-field placing and overall an 8th place for the
series. Of course in hind sight its very easy to say
where our mistakes were. We had a very fast car for
the NZ champs at Cromwell but the mistake was we had
altered the rear suspension exclusively for Cromwell
and when we ventured north the car turned out to be a
very loose pig. Cromwell's track surface was excellent
most of the time and it suited the Nissan but we
failed to make the set-up work at any other track. The
short right side panhard bar we changed to for the
champs, altered the roll centre too much and we
struggled with this arrangement right up to Napier
where Prozac (Elliott) had to cut out the tubes and
bits to alter to a longer panhard hanging off the diff
to right side mounting on the chassis. This was very
similar to the Jacobs ladder we ran for all these
years. At Wellington for the last round of the series
we managed to hang in there but my driving was erratic
not knowing what the car would do in the corners.
Playing with set-ups during an important race meeting
does not work as you don't have confidence in the car
barrelling into a corner passing on the outside and
hoping the car sticks. I can tell you it was most
frustrating being passed by cars that normally we
would leave behind. I hated it. The top dog during the
SSCAR series was without doubt 1NZ Shane McIntyre,
very fast and consistent at all tracks and deservedly
the series winner. Interesting point to me was second
place Grant Flynn in a 350 cube car who mixed it with
the bigger hp cars. Goes to show that the guy with the
most hp is not always the fastest. Prozac and I drove
back home from Wellington disappointed with our north
island jaunt and discussed the mistakes we made with
the suspension. All along 34T was fast but slick
tracks continued to be our Achilles heal and over the
years we have tried 3 or 4 different arrangements in
the rear end in the search for side bite. The last
change to short panhard was a backward step but the
longer bar was back in the right direction and only
required
some track time to sort out the roll centre heights,
torsion bars, shocks, ride heights and so on?? Back in
Dunedin and Prozac readied the car for the final
meeting of the season, Easter at Cromwell. No changes
made, just reset the chassis, plenty of fuel for 2
nights of racing and a plan of the different set-ups
we would try. Three races on the first night, drop the
roll centre 50mm, some stagger and tyre pressure, and
beauty we are in the right direction again. For the
second nights racing we started with the previous
nights settings and are in the ball park. I had 2
races then Shane Maaka had the remaining 2 races which
was good to get another drivers perspective as we
continued to fine tune the chassis. For the final
race, we went to the softest shocks we had available
and Shane found his feet in the turbo car passing cars
with ease. The set-up was close to correct but still
required some bar changes for different tracks.
Arriving back in the pits, Shane could not believe the
horsepower of the Nissan, 100 hp then 700hp which made
for an exciting ride but different driving style. Well
34T has sat in the garage for 3 months waiting for me
to make up my mind if I retire or continue racing. The
last season was to be my last and I was resigned to
pulling the pin. However the best laid plans left me
with unfinished business of a lousy season, and new
remits passed at the recent SNZ conference allowing
some changes to the rules in Super Saloons. Another
reason was the enjoyment of racing in the North Island
SSCAR series and Paddy North and I agreeing to see if
we can resurrect the south island series. Several
drivers commented that without the series last season,
racing was limited to their home track with the same
drivers and lacked the competition required to
maintain speed. There was concern that if a series
failed again this year, several cars might drop out of
the Supers or become Saloons resulting in a spiraling
down of numbers and perhaps merging of the 2
classes.The Super Saloon drivers are meeting on the
11th July for the prime purpose of gaining commitment
from the drivers to run a series over 4 south island
tracks and put in place management to secure the
series for the future. To date we have an excellent
response from over 20 of the drivers and should have a
good turnout at the meeting to agree on race formats
and other details to make for a successful series.
Already the numbers are improving with Wayne Andrews
and Shane Maaka buying cars for the coming season. So
now what for the Nissan. The engine has proved to be
reliable and still fast enough to be a front runner.
The suspension only requires fine tuning
so will not alter this. Although I have a V8 motor
sitting in the shed, the FJ20 is made for the chassis
and will remain where it has been for 11 years. Today
I lifted out the motor for its annual fresh-up and fit
a new bell housing to replace the repaired unit that
was destroyed at the champs when the flywheel dis-integrated
at 8500 rpm chopping through chassis tubes just
missing my toes. The rule changes in the Supers allows
for the wedge shape American style Late Model Dirt
bodies that will hopefully lift the appeal of this
class.
Will the 200SX Nissan retain the original body? What
do you reckon?
For the next update I will have results from the
Supers meeting with more details of where and when.
Maybe some photos of a Late Model body?
Ray
Great stuff Ray.. thanks for the
update. Check back for the next update...
