when I step on the throttle in fifth gear the clutch (brand new) doesnt quite catch ...it'll rev a grand or so before it does finally grab fifth ...running 10 psi of boost. Whats the problem?

Hmm what kinda clutch is it? did u get any oil on the clutch? Try adjusting the cable.

Who did the install? When'd you get a clutch? Did whoever installed it resurface the flywheel?
