How many Gs did factory 944T Cup cars pull?
I can't remember this issue being ever mentioned when talking to people involved in the Series back then.

Duke

It's a valid note. But at the same time I've heard from people being involved back then that "everyone" pulled the wastegate pressure line so that the turbo boost went sky high.

Of those remarks from back then we might learn 2 things. 1) Perhaps we don't hear about the real truth from back then. 2) Perhaps they changed engines more often than underwear.

Thom

Heard about cheats too but replacing short blocks every other race must have been pretty expensive - and rather lucrative for the factory - considering the number of cars on track. This plus the fact the shells were sometimes badly damaged suggest this was a very expensive Series.

Duke

There are many things not suitable for track use on a stock 951, still there are very few items changed on a Turbo Cup car. I guess that's part of marketing (which the cup series is all about).

Can't imagine those Cups generating nearly the same G's as a modern race car with all the differences.
Duke were you still running only .6 bar?

Duke

I agree. But I was running R-specs at the time so perhaps that's about the same as the Cups with new slicks.
I had just raised the boost to 0.9 bar..

Thom

I would just have thought that the Cup series would have been regular and consistent enough to provide a significant failure rate, even if the cars were probably not pulling as many Gs as they do now thanks to lower profil tyres, more power, etc.

What was the redline on the Cup cars?

Duke

Stock, 6480 rpm.

Even at .9 bar I’d imagine you were pulling greater G’s than an original Cup Car. Modern R spec tyres that are quite a bit larger and stiffer than a 25 year old slick plus your car would be much stiffer, lower, better suspension, better lsd, downforce, 3L 16v v’s 2.5L 8v…etc.
Not saying this is a direct reason for the failure, but you’d have to load those stats into the pile for troubleshooting.

Now you're just messin around. I still laughed.

Dukes issue is the reason I went with the V8. Fear of this exact failure was huge. After all was said an done, I knew I couldn't afford a dry sump system for this motor right away with all the other parts, but couldn't afford to not buy it and blow that one with the possibility of trashing all those expensive parts. The V8 Dry sump was about $2K cheaper than the similar one for the 4Cyl. and much easier to acquire with tons of proven results. And I can afford another V8 if it breaks. The decision was easily made.

I am very sad this happened to Duke in every way. Even though I made the decision above, a 3.0 16v is my first love and support his engine choice and dedication. He is clearly too far in stop now, so suggesting a V8 anymore than we have "joked" about is probably a bad idea. I can't wait to see the videos when he completes this project, - a fantastic monster.

Thom

Just for the record, the latest Cup cars running "290hp" had the limiter set at 7000 rpm. Anyway I agree that Duke is here certainly pulling significant more G thanks to a much improved chassis set up.

I wonder how many G’s the cup car guys were pulling as the bounced of each other!!

If you haven’t seen this before….enjoy it! Scott Goodyear at Tremblant driving like a possessed wack-o!
