Do you know about the SpeedGT WC GT3s? Basically, they are very close to specs in a narrow body, especially a few years ago. Again, they share many of the same suspension bits and are made from the same cup chassis core. The motors are different, but in the end, an unrestricted WCGT motor make near as much power as the GT3RS with its ALMS restrictors. I think dynos were posted a few years ago. Other than that, the cars are pretty simular. If you look at laguna Seca times of 1:28 for the WCGT cars and 1:25 for ALMS, they are pretty close considering the WCGT cars are running smalller sized tires and DOT Toyos.

I become friends with Kip and the Driving Ambition guys. The car is amazing. pretty awesome to see him work over all the nascars and Superproduction guys in the other group, as well as double stinting in our ITE DOT group!
Really a wolf in sheeps clothing.

The FX NsX is running stock ride hight? Hmmmm, maybe after putting on taller tires . Kip is running pretty smalll front tires too because of the stock fenders. 225s in the front and 275s (I think) in the rear. IM pretty sure the car can run a 1:30 at laguna right now.

Very cool to see this kind of hardware out racing, not just time trialing!

Pics of JGT, FX NSX and a stock NSX

That ride hight doesnt look too stock to me! But, NSXs are pretty low for a stoc street car to begin with. They sure make fast race cars with a little bit of power added. (or a lot )

 

From what i've found:

600hp ALMS GT1 Aston Martin DBR9 _ 1:21.012
480hp ALMS GT2 Ferrari F430 GT _ 1:23.611
500hp Grand-Am DP Crawford-Porsche _ 1:23.712
500hp SCCA WC GT Corvette _ 1:28.463
___hp SCCA WC GT Porsche _ 1:29.764 - randy pobst pole time 2007
380hp Grand-Am GT Porsche 911 GT3 Cup _ 1:32.798

"~" stock ride height. Also you can't compare any reference points on teh FX car due to its wider fenders, lower front bumper and side skirts, but the ride height is well over 4" from the jack points - near stock.

 

That seems about right....

I remember a GT1 ALMS C6R pole position qualifiying time in the high 1:19's....

Kips red NSX ran 1:30s' in SP (slicks I guess) and 1:33's on DOTs in the ITE race....last time at laguna....

I've also talked to the Driving Ambition guys and the owner of the white TT NSX...they are all good guys.....

It would be VERY interesting to see the red NSX battle with Anderson at Laguna...since the NSX on slicks is about .5 seconds a lap faster than Anderson...

 

It is amazing the times that these cars are running now. But, if you go back to 07 and look at the porsche GT2 (or was it GT) in ALMS, they were in the 1:26s in the race while speed GT WC porsches were in the 1::30s

Where did you get that hp number for the WCGTs?? They are probably closer to 550rwhp. Heck, andersons car is near 520rwhp and he would get walked over by the new comp coupes and Vets in WCGT.
Porsche RSRs were, about 4 years ago, near 440rwhp, there have been dynos of the WCGT GT3s in the same range without the restrictors. (420ish, rwhp)
I think even the standard GT3 cup cars are rated at 420fhp now
Grand Am GT3s with the slightly wider bodies than the GT3 cups, have more power and I thougth they were into the 1:29s now at Laguna.

I know that the body on the NSX is pretty custom, but I have a hard time believeing that they wouldnt have lowered the car vs the stock ride hight. But if you say so, I can imagine it.

Here is a picture of Kips car, as it is very stock looking but would be a top runner in WC GT. Kind of amazing comparing the looks of the WCGT cars, dont you think?

 

results for the Grand Am Rolex porsche GT3 at Laguna this year, in the race:

15 87 GT 3 Keen / Werner Farnbacher Loles Racing / Porsche GT3 101 1:27.986 77 81.597

qual:

17 87 GT 2 Keen / Werner Farnbacher Loles Racing / Porsche GT3 1:27.531 92.045

 

This came from AMS and all the other teams that were out there competing. It's no secret there are Yokohama Advan DOT's that the Japanese get that you can't get in the states. And we all know the usual A048's are not very fast at all, but these are a whole different beast from what they say.

If you put the HKS Evo and that NSX on the same tire, they very well could be pretty even.

 

Thats kind of what I thought. At time, the tires didnt strike me as something that unusual.

Now, HKS and NSX on same tire, the HKS would be faster.
If I recall the HKS EVO was on a 40 tread wear DOT tire and the NSX was on full slicks. whatever the NSX changed to, it would have to pick up a full 2.x seconds to be faster. Its fast, but I dont think it is that fast.

mk

 

I don't care one way or the other, just stating what I've heard from various sources. The HKS car is a beast, no doubt about it, I have no idea which is faster.

 

I still dont know what tires they were on. Ill have to check. I only care because i was there and that HKS car was FAST!!!

 

Like wanna911 said, those were not really "40 treadwear DOT tires", but they were remarkably quick. It also wasn't said that the NSX was held up in the esses a bit on its fastest lap.

Bench racing is fun...

 

Mark quit talking out of your *** here. I have driven a couple of WCGT vettes in the past. They don't make more than 550rwhp trust me. They do make close to 500 with the restrictors they are forced to run. Where these guys make up their time is not on the straights but in the downforce the aero creates on them. The fast Vette teams spend a lot of time developing an aero balance for a factory car that sucks in this department.

 

LMAO! Same story, different verse...

Mark - If there was a professional bench racing league, you'd be on the podium.

 

Hey Seth,

I didn't know you were on Rennlist. See ya around!
