About 630 RWHP with a 2.6H. Pulled apart to do a headgasket, the flywheel had some cracks in it and the clutch was in bad shape. Replaced it with a ProMotion 650HP kit.
Just pasted 75k, but I'll be replacing soon. Not sure either what I'll replace with... so many options/ opinions.
Probably gonna get a spec stage 3... still got another year to research and decide though.
Mine is still holding well with a 2.3 Whipple running 18psi, but I also only have 16k miles on the clock, so we'll see. I plan to go with a twin disc like the McCloud RXT when the time comes, but see no point in spending all of that cash until I have to!:burnout:
On the stock clutch as well. Stock horse power lvl till 10k miles then pully and full exhaust at 475rwhp. Now I have a 2.8H KB at 20psi making 620/560 for 1,500 miles holding strong.
29,000 miles and still holding fine. Been holding the Whipple since 2006 @approximately 16,000 miles. Only about 4-5 drag passes when new and stock.
Lot, of the "other type of track" though.
