I will most likely have to upgrade my clutch if I put down more than 450whp. I should be good for now, but when I get a new diff and race axles I'll have to upgrade.

Are there any clutches rated for 550-600whp? I would like a sprung hub, but may not have that option.

Hahn mentioned a twin disc setup. Does anyone have more info on this?

I'm pretty sure Hahn's is the prototype for that set up, I'm not even sure who makes it. But I believe it is a Clutch Masters.

I'm probably going to have my fairly new Proactive Stage 2 clutch redone by Southbend Clutch. I think 6 ceramic pucks should be fine for now with the 65% increase in clamping force it has.

I also might check into having the clamping force increased to 75-85% over stock.

Holy Jesus!!!!!

It is Clutch Masters that does the Twin Disc... at about twice the cost of a stage 3 or 4.

It would be nice if we could get the pressure plate upped in rating. If Southbend can do that with our pressure plates, pass the word along. I've yet to hear of a company that modifies our pressure plates though.

I'm currently running a 6-puck ceramic myself, and that's done a great job of up to 20 psi, thus far.

I have FAR more trouble at this power of keeping traction with my 225 tires that anything else. The Kumho's tend to lose their ability to grip this much HP fairly rapidly. I know a drag radial would get it done, but I'd like a sturdy street tire for my weekend joyrides.
