Stock clutch
How much hp/tq can a stock b18c1 clutch handle? (hydro clutch)
The reason I am asking this is because after installing an tuning my new stage2 skunk2 cams (about 24 hours) I started to notice some strange clutch happenings, like only when shifting gears(at any rpm) when releasing the clutch pedal it kinda pops up about half way up, like it has a sticky spot and it kinda stays there, then releases... I am going out and testing it some more to get you folks a better description

Stock clutch is good to about 200 whp. What kills more stock clutches is rpm as opposed to power. The springs in the clutch disc hub like to break out when subjected to repeated trips past 9,000 rpm.

According to the math the torque capacity is about 186 ftlbs. Of course this varies with heat and wear, etc. The pressure plate is good to about 8500 rpm before the little retainer clips start to come off and the clutch will not disengage. I disagree with the rpm causing the spring failures as the one person wrote, but it does contribute to the wear. The window of the stock disc hub around the springs will break when you engage the clutch too hard (drag launches).

Good info. Because the little window (or whatever the proper term is for it) seems to break out at high rpm, I thought that was the cause. It could well be that hard launches cause that thing to go, and then the spring pops out and can get caught between the pressure plate and the disc and cause all kinds of problems.
