I had the original TSP 233/239 in my '99 Trans Am M6 and it put down about 398RWHP/360RWTQ with the LS6 intake but then with better tuning (mail order at the time), and a home-ported Fast 90/90 setup it made 428RWHP/383RWTQ with stock 241 heads. Mods were Pacesetter LTs, ORY, magnaflow catback, cutout open, UD pulley, open loop SD tune with MAF removed in favor of a 4" pipe coming right off the SLP lid and into the Nick Williams TB. Also stock clutch, stock rear, and stock injectors. I'm sure with 243 heads I could've been closer to 450RWHP.

Numbers and mods in my sig. I have the .598 .603 lift model on a 113LSA
When I was on a port matched LS6 intake it made 446rwhp 406 rwtq.
Heres a video before the FAST 90/92 setup.

Had the 233/239 in my '01 Z06, with Callaway CAI, ported TB, TSP headers, pulley, etc... it pulled 430 rwhp (110k miles on the engine, original 243s of course). Peaked around 6,700 if I remember correctly. Stock clutch immediately started giving me trouble. Was still able to daily drive it, though.
Rebuilt to 347 (10.6 comp), ported the 243s myself, switched to bigger Kooks, sold the car. New owner pulled 450-ish, then added FAST 90 and pulled 460+. He also said Centerforce clutch was doing OK.

The Centerforce is holding up fine still. Car now has 122K miles. I've added 300m Hardened axles and a DTE rear brace since then. Hoping to swap out the cam and go with a Vortec T-trim later this year. Or go to a G5x4 and Trickflow heads.
As for the centerforce DF 12" here are a few vette owners that are still on theirs: http://forums.corvetteforum.com/c5-t...-clutch-2.html
