The best $85 I've spent in a long while.
I went to my first Eastern Creek Private Practice day for probably 5 years. It was 35 degrees at 11.00 this morning. And that was in the shade!
This was good for getting heat in the tyres. It's been a struggle to get the 195/55R15 Yokohama ADVANs into the 60 degree temperature window with a
light car of 760 kilos and just 99.9 RWHP.
John Ladomatos manned the Pyro for me just after pit entrance. To get an accurate reading I pushed the car on the last lap, right through the last
corner and suddenly into the pits before the temperatures have time to dissipate and cool.
The right rear, the loaded side, was 86 in the inside edge, 84 in the centre and 82 on the outside edge. That means there's a tad too much negative
camber on the rear, but not a lot I can do about that.
The right front was 62, 68 and 68 meaning I probably need a bit more camber and maybe a little less pressure.
The high heat didn't seem to trouble the engine. It was happy right around the circuit and humbing down the main straight up to 6200 rpm in 4th. I
probably did 5 or 6 laps in each of the 4 sessions. I called it quits when the needle on the temperature gauge went past the bit with the numbers.
It was great to reaquaint myself with the car. It's so easy to drive. It has a bit more understeer but I like it. It seems that if I induce a bit of
understeer on turn-in and then meter it with the throttle the weight shift to the rear is a lot more gradual. The rear will step out if you want to
induce it with steering input or lifting off. But I'm not that confident with it yet.
There was a few traffic problems in the early sessions. But I found the cars that I passed didn't seem to want to come out again in the following
sessions. That included a Supra, R33 Skyline, current WRX and an EVO 9. The EVO was funny. His lines were crap and he had no corner speed. I sat right
on his clacker from turn 2 to 12. I'd get right up beside him exiting the turn onto the straights and then he'd blast away down the straight like I
was standing still. Then I'd catch him under brakes. Finally he let me past between turns 5 and 6. He picked up his pace and I gradually pulled away
for the next 2 laps until the temp gauge told me that the fun was over.
It was awesome fun. I think the car is fine. There's still more in the driver. I could enter a few corners faster, brake a little later and use more
throttle in places. But that will come with practice. Bring on the next track day i say.
I've now done more circuit racing in 2009 than I did in 2008.

Hi JVL,
I'm not comfortable when you mention my ass and midmount in the same sentence.
Are you still putting the VR6 engine into your Oval?
I'm heading back out to Eastern Creek this Thursday night with no rear sway bar to see what happens.
Please explain the popcorn to me.

Be interested to hear your report on this - i have a rear sway bar (not fitted) and am still contemplating installing a 2inch narrowed for the front -
not sure if i need them or not.

Hi Mick,
In my experience a wider rear track will cause snap oversteer. I used to run Fuchs 6 & 7s. Now I use cookie cutter 6s and a slightly wider front
track which makes my front and rear track identical. From memory you have Fuchs 6 & 8s? In other words a really wide rear track if the offset is
outwards.
Theoretically the rear bar will also cause oversteer.
Do you have dropped spindles? These restore the factory front trailing arm angles and keep the front soft allowing weight transfer unlike the adjuster
only method of lowering. This can potentially generate great turn-in which means less weight on the rear wheels after braking which can, create more
oversteer.
I'd drive the car before fitting the rear bar.
That's pretty much guess work. You may like the car this way. Or it may not do what I suggest. Doing some pyros will help diagnose the handling if
you're not sure. The only way to find out is to drive it on the track and gradually creep up to the limits. Well that's the way I do it.

yeh, i can't wait! Got my rear coils over in (so much better getting the rear end off the ground - pics in 'my ride' link in signature)
Yes, 6 and 8 fuchs, i have dropped spindles but no sway bar what so ever on the front.

Front swaybar
I think you should run at least the stock front swaybar.
I drove a 1500 once with no swaybar on the front and it felt terrible.
I think "How to hotrod your volkswagen" says whatever you do don't run without the front swaybar.
Maybe somebody else can explain why.

No oversteer.
I notched up another 3 sessions last night at Eastern Creek. I've probably done 38 laps around the track in the last week and I'm very comfortable
with the track and the car.
I've taken the oil temperature off the gauge 7 times, that's past 120C, and the engine seems fine. No oil leaks and a smooth idle, it sits in
traffic happily. I must say I'm a little surprised, surely I'm pushing my luck.
The car still turns-in well but the understeer is noticable but not washy. It means you turn it a little earlier, or have to wait longer to get on the
gas. But it does give you more confidence turning in. There's absolutely no incling that turning-in will make the car swap ends. As a result I almost
don't have to brake for turn 4 and the car gets drifty on exit but its leading with the nose slightly.
This would be the perfect set up to build confidence for somebody getting on the track for the first time.
But, I must stay its a little boring. I need to get a time to see if its slower or faster than normal.
I'm getting the negative camber reset to 2 degrees on the front and I'm goint to reinstally the 18mm rear bar with new bushes.
I tried countering the understeer by dropping the nose 2 notches on the bottom beam adjuster and putting some weight in the spare wheel well but it
did stuff all.
I hit the track in the middle speed group with some corvetts, FPV Falcon, a couple of WRXs, an EVO a lowered MX5 with a rollbar and R-spec rubber plus
a few other cars. They always look miffed when I line up in front of them because they think they'll be stuck behind the VW. But I never saw anyone
in my rear vision mirror all night. But I've probably got more experience than most of the people there. But they don't know that so the concept of
a racing beetle is still amusing.
Finish your popcorn this time JVL?

Sounds like you're on the right track (pardon the pun), CT. What camber are you currently running on the front of the car?

I reduced the camber for the Dutton rally to get as much lock as possible to do 180s around witches hats. The car had so much turn-in and not much
body roll it didn't really need it.
The car was set at about 1.5 degrees. Now I'm trying to tune the neg camber in so that the temperature is even across the tyre and I'm getting no
understeer scrub. The new neg camber will be about 2 degrees.
The rear is 2 degrees and the temps indicate it should be less. So I may raise the rear a smidge but that's a day long job!
I'm finding this stuff interesting. In case you couldn't tell.
Regards CT

Hi Vassy,
Good luck in the shed. I hope you find the tinkering bit as fun as I do. Mind you, I'm easily side-tracked.
Getting out on the track and trying simple stuff beats the hell out of sitting at home saving your pennies for the bling bits that should make your
car handle like a Porsche.
What's your ride? How long until it sees a track day?
We should all be working towards the VW Nationals event at Wakefield.

I am at the beginning of the build.
Just stripped the pan halves off the tunnel yesterday and prepping it for the new halves.
It is a 69 semi auto pan converted to manual. The body is a 54 oval.
I have almost everything for the chassis build which will see out the next few months. The major items missing are the motor (only carbs, heads and
exhaust currently), seat, gauges, tyres, bumpers.
The gearbox is a dangerous special and ready with quaife lsd installed and close ratio 3 and 4th and 002 main shaft, etc.
I will build a car and an engine that conforms to under 2 litre improved production specs and run hillclimbs and lap sprints.
Hopefully something like the Dutton after a year or two of getting the car (and my own skills) in some kind of order.
Will get the car build in my rides in the next few days as I get more underway.
I hope for the chassis to be ready by May ... engine is a finance question. I would expect maybe June to have the engine well underway.
Track this year definitely. :-)

hey CT.......
those engine temps with the cooler mounted down the front? HOT!..........not keen to try hoodjax, or have you done so before?
so tell me,(serious question) having driven Jaks car, if your donk goes kaput, what would be go in it's place?
would be interested to see pics of where you ended up mounting the cooler.
i've got a spare berg temp dipstick i'd like to dontate to you in the name of experimentation too........flip me a PM

Hi Daimo,
Freeway speeds are no problem. On the last two times I've driven up to Warwick for the Drags the air temperature was in the 40s as I left Sydney and
the oil temperature is about 100C. Normally it runs between 80 and 90.
A supersprint is usually only 3 or 4 laps which is fine too.
But Eastern Creek last week was pretty extreme for a few reasons
- The air temp was in the mid to high 30s
- I was doing 5 or 6 laps at a time
- The average speed is about 118kmph
- The engine spends 10 to 12 minutes between 4500 and 7000 rpm.
I think the oil cooler setup is brilliant.
I think the engine lid popped at the bottom by 2.5 inches and no front engine tin works a treat.
The biggest weakness is the standard cooling fan. I think I need a Porsche one. But that was never in the bang for my bucks game plan. It sits on the
'never gunna happen' shelf with rear disk brakes and a LSD.
The Castrol Formula whatever is apparently good to 150 degrees.
I probably only get the oil up to 130 for about a minute or 2 because when I see it past 120 I usually finish the lap I'm on. Usually.
Welcome back from holiday Jak. You must've missed your vw fix if you're on here!

corolla or escort? Cheers

Hi CT,
I should pay more attention.
So how much faster (speed too please), was your PB at Warwick?
That was basically just the smaller cam and the rockers(CB perf K8 x 1.4's now and old cam W130?)
Sounds like it is making more usable power?
Merry Christmas!
Dave.

More usable power.
Hi Dave,
The cam and the ceramic coating were the only changes.
The engine is alot more loser-friendly but didn't seem to have the same shove in the back from 4500. I now shift at 6500 with the CB K8 instead of
7000 with the W130.
It surprised the hell out of me that it's faster on the circuit and about 3 - 4 tenths quicker at Warwick. I think it's about 2MPH quicker but I'll
have to check. Surely I've exceeded the old combo's 99.9 HP!
I'm contemplating a DMS 78mm crank for next year. Just to give me an excuse to keep tinkering.
