forgive my ignorance, but i am not sure what type of car you are building...ford, chevy, pontiac, etc........
personally on clutch's, with the horsepower you are looking at, i would look at a spec clutch......currently i am running a spec 3 and it is supposed to be good up to 600hp at the flywheel.....if you are above that, look at a stage 4 or 5......out of all the clutch's i have messed with, the pedal play on this clutch is excellent....it is smooth and doesn't kill your leg driving it on the street....i have a friend that own's a company called mentaladdictionmotorsport's and he sell's spec's for an awesome price.....

With the twinturbo's.....i wouldn't go anything under 8.0 to 1.......if you can grab that 8.3 to 1......you will be fine on 93 octane fuel......just don't slam alot of boost into it....keep that around 10 or under, till you get race fuel in it, then you can up the boost for some serious play...
