I have a $5k pro-stock clutch set up for my race car sitting on the shelf rusting away, That didn't include the custom flywheel either.

 

Naa we don't need tripples, man just exedy twin or or a osgiken will be 1500-1700 ish for a plug and play twin disk setup. Their a designed race clutch, not just a beefed up stock clutch. Just safer. I'm making 200hp more than all my friends and I haven't broke an act, but saw 2 pop...

 

I may be wrong but I have always been under the impression that the twin disc setups start to tap out right around the same area as the single disk 6 puck. I remember reading somewhere that the torque capacity was 4-500 and the triples where up at 800. Like I said I could be wrong but I haven't seen or heard of anyone in your power levels using a twin disc for drag with a H-pattern trans. It would be an expensive mistake thats all im thinking about.
