Street/strip clutch & flywheel package

[weedburner]

The sbc version of a Ram Powergrip is organic/metallic dual friction and under $400 at Summit. Its a 550hp rated dual friction with very good street manners. I currently have one on a 19lb steel flywheel behind a 600hp 355 with a 250hp plate. Nitrous hits after a slight delay, no problem dead hooking radials @ 2525lbs or spinning the Powergrip 8500+ rpm. Very happy with it for a street/strip application.

I have run full face sintered iron solid hub units on the street, worked ok but hub splines and pilot bushings wore fast and didn't like the squealing during casual engagement. The dust also caused problems with the o-rings in my hydraulic throwout bearings.

The all metallic puck 650hp rated Powergrip HD has sprung hub and a marcel, but it occasionally shudders in my application when trying to feather.
