i need a heavy dity clutch that can take lots of abuse and hold up to 400hp cuz im getting a 100 shot of nos, should i go with a centerforce dual friction clutch 90% holding capacity or a new king cobra clutch 40% holdin capacity

 

Centerforce Dual Friction. I beat the living **** outa mine in my other Cobra and it never had a burnt clutch smell or slipped.

 

I personally think SPEC has been good to me.
I would say a SPEC Stage 3 if you dont intend to do anymore torque than what you have for right now.

Then you need to find out if you want a billet alum. flywheel, or steel.
Billet Alum is best for the street racer, steel for the track queen. IMO

 

In my opiniong king cobra sucks. I had a spec stage 2 a while back and beat the living hell out of it and it held up great. The king cobra just didnt last as long as i would of like it to. Now, i switched back to the spec stage 2+.
