Think the concern is that if the door comes open during an accident, the window net no longer provides the protection intended.

In the GT rules, it didn't mention anything about the GTB, but at the same time none of the formula's have a 996 based engine. So it looks like the GTB would be used and not intertwine with the formulas?

The rules committee has not completed its review of the 2007 rules proposals. We will have them posted by the middle of this month. Stay tuned, an announcement will be posted on this forum, as well as a link on the PCA.org web site.

Did anyone download the proposed rules when they were posted? I want to see the proposed class for the 3.4 996, as well as the class above and below it. If you did can you email to mark_d_mcguire@hotmail.com

Still even so all that is just a proposal. We will see what PCA is going to do with it.

Well there is a 200lbs weight increase for the 997 (3.6) and therefore a reduced power/weight ratio 996 = 9.56 997 = 9.92. I believe that the power/weight cut off was at 9.85 or so. But also look that 997S is in 4. I would not think you would want to run a 997 (3.6) in the same class as 997S (3.8) even if he 3.8 weights 50lbs more.

Most seemed to think the 997 would still be faster.

I agree with the weight difference. However, in this thread here;

Frankly this is one major issue with classing based on rated hp and curb weight. It is tough to put the 997S in the same class as the 997. So logic says bump it down a class.
What about 996? Same issue with the 3.4 vs 3.6. What would be much easier is to run the all 997's in one class, but at different weights for the 3.8 and 3.6. Same for the 996's. However then you would not be running at "curb weight" anymore.

The Turbo Cup chips run a slightly more aggressive ignition advance and have a little higher boost curve in the mid-range rpms, but it drops down to near stock levels by the upper rpms. So in effect, the peak torque is higher, but the ultimate horsepower is not significantly increased over a stock Turbo S.
Factory numbers rate them at 250 bhp and something like 275 ft-lbs, where a stock turbo S is 247 bhp and 258 ft-lbs. Realistically, they are probably making in the 270 hp range. Which is not dissimilar to the actual horsepower that 3.6 964 motors are making in race trim in the same class
If youve run into a Cup thats making well over 300 hp, its not doing it with stock/factory components; would need a bigger turbo, boost control, and ign/fuel management upgrades to do it - all of which is big time cheating and obvious to any scrut. that knows anything about a 944T.
