I think that have a toothless, lame dog in this fight. I do think that any of the FEWC guys would be supporting 50 lbs reduction for 3.2s as it takes away our main competitors in E which likely reduces competition.

F class or E class 3.2s? An F-class chipped out 3.2 will walk you down the straights that's for sure. Stock 3.2s shouldn't.

S2s walk 3.2s as it is today.

I do want the 50 pound relief as a prep and I think 3.2s should be allowed to run closer to SC weights though See you at TRAC !
Line up a well prepared 15" hoosier'd euro SC next to one with 17" wheels and you'd be surprised at how much lower the ride height is as well...CoG advantage.

All E class 3.2s and all the fresh D cars walk away. But in reference to my earlier post, comparing my original motor and largely home-built car to these fresh, race-shop prepared cars isn't really apples to apples. If you say the fresh 3.2s are at a disadvantage to the fresh Euro SCs then I'll take your word for it.

Pardon my ignorant question, but does this rule disallow the use of the 8:35 ring and pinion set that was available and used in the SC-RS cars produced in 1984? Earlier in the discussion about the shocks someone said something about it must be available as an optional part from the dealer at the time the car was for sale. What's legal here with respect to the R/P ratio? Is the 8:31 the only allowable R/P set?

8:31 was the r/p available on the cars in question back in the day... hence to stay "stock" one has to run a 8:31. 8:35 or 7:31 would be a preparation and bump the car a class.

Thanks Fred,
I knew the 7:31 was out, but wasn't sure on the other one. Many of my European customers have to prepare their car to FIA homologation rules and are allowed to use the 8:35. I'm still learning the nuances of the PCA's rules and wouldn't want to advise someone to install something that would make them illegal or inadvertently move them into a different class.

954 are in I w/ 964RS, 993RS&RSCS,'02-05 996, '05-08 997 Carrera S (3.8), 06-08 997 Carrera 4S (3.8), '09-10 997 Carrera,' 09-10 997 Carrera 4, '09-10 Boxster S, '09-10 Cayman S, '10 Boxster Spyder

it would be interesting if someone showed up w/ a 954, 8:31, 8:35 & 7:33 cwp were an option, as were some very happy RSR cams

How does a 915/62 compare?

the only difference between a 915/61 & 915/62 is 5th, the /62 uses 28:22

so speed in 5 @ 6800 for the /62 is 152.8mph for 275/35 x15 and 169.4mph for 275/35 x18

Cool, so they actually explicitly class the SC-RS even though they barely made any of them. How about the Carrera Club Sport? Is that thrown in with those cars as well, or is it classed with the rest of the 3.2l's?

"Had" is the operative word. I believe that nobody runs in the 996spec class any longer with POC: 2 cars are for sale (1 not being driven any longer), 1 has been modded beyond the spec and runs GT3, and the other car runs GT4 since there's nobody to run with anymore.
