Which Clutch up to 450hp Street car with some drag racing?

I was thinking about the Powergrip from ram which is organic one side and metallic on the other good to 550hp. The Powergrip HD is metallic on both sides and good up to 650hp. That seems a little overkill for my motor which will never make more than 450-475 hp. Anyone run the ram Powergrip (dual friction clutch)?[/QUOTE]

The Ram Powergrip would be similar to the McLeod super street pro clutch (dual friction disc) but mcleod is a diaphragm pressure plate vs rams’ borg and beck. The Powergrip HD would be similar to the McLeod extreme (I could only find it on brewers site).
