wow Derek...you've been stockpiling parts. We will need a thread started detailing your plans and purchases so far!

As far as the Stage 2...just make lots of power and abuse it!

Oh, gosh, my spare bedroom is filled with stuff and the rest is in my garage!

The B&B SS exhaust is sitting in my garage and all of the parts I need to install it have arrived - let the fun begin! The clutch and flywheel are also in there with some Bilstein's I bought last year off of Pauerman. I may as well use it since I'm not hard on my stuff and have no intention of abusing my 951.

It's amazing how much you can learn in less than a year just hanging out on this site not too mention the $$$ I have spent. If I had put that into my Bronco, it could climb a wall by now.

This thread alone has been very helpful.

Unless you launch 24/7 a Cup PP/clutch is all what you need and WILL hold around 400 whp.........a KEP is total overkill on those cars, the clutch is/was never a problem in the 951.

Can anyone tell me the difference between tha Cup disc and the 930 disc? I've talked to Kirk at Zims and Jason at Paragon, and from both descriptions none of these modern clutches have the little helper springs that are notorious for falling out. The 930 clutch has 6 main center springs, and the Cup clutch has 4 that are slightly larger. Is that the only difference, or are there other differences with the friction surface? Does the difference in number and size of the springs make the clutch engage differently? Does the Cup disc have more grip/friction?

The 930 is thicker and also has a little wider friction surface. It actually goes inward past the pressure plate surface

I don't think you will feel much difference in the way the clutch engage. In theory, the 930 should hold more torque with all the other clutch things being equal.

I might be misunderstanding something along the way...

I am using the new Ford ‘coyote’ 5.0 V8 (420hp stock – all aluminum DOHC with variable cam timing) mated to the 951 torque tube (with an extension) and all the rest of the 951 drive train (transaxle) and suspension.

Have used a Spec Stage 2 hybrid for last three years racing. Been excellent for me. I could live with it in a street car unless you were doing stop start traffic.
