R32 Gtr

[StealthX]

Hey guys got into a bit of discussion with a mate the other day, we were talking about the R32 when it came into group A racing in Australia (the aussie touring car champs) and he said something about they raced with only 2wd engaged??

Can you guy confirm when and what types of racing they used 4wd or 2wd?

Cos I know they were outlawed in 1993 because they won 4 years straight and the only thing that could touch them was a sierra cosworth...

Did the R33 GTR compete in Australia? i.e. DTM, super touring or super GT?

[Marlin]

I for one look forward to this thread getting to page 55 of the Motorsport section.

R33 is a funny one. Super GT didnt really exist, nor did Grp A. The Japanese did run 2L Touring Cars for a while much like the Europeans. The R33 did run at Le Mans etc

As for the R32 GTR being run in 2wd. For about 1 second off the line they used to launch in rwd before engaging awd. This was done to make the drivetrain more reliable by reducing the shock of awd launches. When racing they did not run variable awd like the road car with ATTESSA, instead they had switches in the car that allowed them to run a fixed amount of fwd depending on the prevailing track coditions.

And wasnt quite 4 years straight, in 1990 the R31 ran a bulk of the races in the SATCC, before the R32 took over late in the season for Richard to take the title. 91 ad 92 weres impler affaird in the SATCC and dont forget that in 1990 they were beaten at Bathurst by the VL Walkinshaw but simpler tasks in 91 and 92.

gosh darn, sorry for not knowing something!

I bet you didn't know everthing at one point in your life too!

Thanks for the reply man!

Over-reaction much? He was just clarifying a couple of points. If you're going to bitch that much about being corrected you better not need to be corrected.

Nah man i was referring to Marlin who said he cant wait for this thread to be buried on page 55...

i.e. EVERYONE knows this, im stupid for asking this.

Sorry lol

[R31Nismoid]

^ lol i gotta agree with Ben...

I mean come on, just watch the footage in youtube and you'll see the GTR's ran in 4WD (and waste a couple of hours going "mmm")

Even a simple google would have told ya all that kinda stuff anyway

[StealthX]

Shit, sorry for asking

FYI I searched here first, and searched "R32 GTR in motorsport" and "R32 GTR ATCC" on Google, didn't come up with much, but i missed thes:

Thanks anyway.

Note to self: Don't post an even slightly vague question in this section again for fear of getting shot lol

Sorry mate, I read the posts in sequence and thought that's what you were referring to. No worries.

Yeah but to be fair the 1990 R32 was very short on development. Have a look at the photos of the thing in practice at Bathurst & the nuts wheel alignments that is was running. (Only one car that year by the way. Skaife wrecked it at Adelaide AGP not long after) By all accounts it was a horrible thing to drive at Bathurst that year.

Also take with a vary large grain of salt anything that was said at the time about the engineering/competitiveness/operation of the GT-R's or for that matter most of the Group A cars. I for one don't even vaguely believe the tiny horsepower outputs claimed by Gibson Motorsports for the Rb26.

What were they claiming?

I can tell you from a recent dyno run the R32 GIO car is only running about 315AWKW's at 1bar........the R31 was about 320RWKW's at 1.6bar.

[djr81]

From memory (A dodgy one at that) the original number was about 600hp. Then it reduced to something like 480 when the boost retrictions were put in place. But hell you can get near on 400 horepower out of a stock RB26 on pump fuel with stock ceramic turbos - hence my scepticism.

Sort of reading between the lines I formed the impression that the GMS cars didn't use the ATTESSA system much and bascially ran (after the start line 2WD mode) in fixed 4WD, rather than varying the torque split. You will note on the old videos the commentators banging on about the GT-R starts which did appear to be better than the other cars - something that is hard to reconcile with a 2WD start.

Cos I know they were outlawed in 1993 because they won 4 years straight and the only thing that could touch them was a sierra cosworth...

All turbo cars were outlawed at the end of 1992. Basically Group A was a dead category and it needed replacing. They went to V8's (Although the BMW's were still ok for 1993) hence no turbos. To say the GT-R were banned is just a bit of Nissan merketing hype, really.

Did the R33 GTR compete in Australia? i.e. DTM, super touring or super GT?

DTM = German Touring Car Championship.

Super Touring = Two Litre atmo cars. (Nissan ran a thing called a Primera? in England & I think Steve Richards was their test driver for a while. Can't remember if Gary Rodgers ran one over here, though.)

Super GT = Japanese formula.

So, no. No R33's ran at any high level sport circuit sport in Australia - well none that I can remember anyway.

Thanks guys!

Exactly what I needed!

The torque split was controlled from within the car. I am pretty sure that as tyre's go off in the rear you would dial(0,1,2 on the switch) on more front split to compensate for the oversteer.

In the picture it's the black box just behind the shifter on the tunnel with the switch and small LCD screen.

P.S. turbo x-trail......doesn't offend me....the last time I looked I thought that forums were used to get info as well!...lol

Again from memory it was:

0: 2WD start

1: Normal running

2: P!ssing down raining ie torque forward.

I just sort of got the impression (Maybe wrongly) that for a given setting the torque bias was fixed.

Yeah so did I!

Fairs fair, if i did a better search I might've found it my info, but searching R32 GTR on here is pretty ambiguous lol

The R32s did not run ceramic turbos. Nissan did a run of 800 GTRs to homologate things like turbos etc. They were plain bearing steel wheeled turbos. You see them floating around from time to time and referred to, funnily enough as Grp A turbos. Doubt they are original items bu probably the same spec turbo.

When Stev Richards returned from being a test and development driver in the UK he ran the Primera run bay Garry Rogers, i believe it was the old Matt Neal Team Dynamics chassis. Though may have been a facoty car from the uK?!?!

So true - The 91/92 vid's i have here has the GTR shooting out of the hole a bit better.

One such example is the GIO car in 1991

Well over a car length before turn 1

Certainly as Craig said above with his dyno results... if it was indeed fulltime 4WD as we kinda suspect, then 315awkw would be very close to 600hp as opposed to 480hp!

Actually... Craig is yours with or "without" the restrictors?
