Question Pumped-up 915 clutch?

915 Power clutch kit seemed to deal OK with stock 930 power.

Unscheduled rebuild and restrained bolt-on goody frenzy ensues. Seemed just fine during break-in, made about 395 HP/350 ft/lbs (crank) when we checked the AFRs.

Seemed just fine for a while longer, too.

Now the clutch is obviously not happy and is polishing the flywheel with less provocation each time. It's got to come out and soon.

I want to pull the trigger on buying parts in the next few days, but I'm undecided what to put back in (although I'm leaning towards a Sach competition cover).

What you guys with 915's and > 300 ft/lbs torque running for a clutch setup, how much (if any) difference in streetability is there, how long are they lasting you and how much power/torque is your motor making ?

Thanks for any help!
