so i talked to a couple companies and all of them recommend a twin disc of course or a solid disc but i know theres some 420a's out there making more power then me without twin discs or solid hub clutches.
Ive been running on 23psi since the clutch doesnt really slip at that boost level but it feels like the turbo doesnt wake up till at least 25psi so i need something that will hold more then 500hp and at least 400ftlbs
