Man some of you may recall when I explained how to setup a good clutch,holding up to double the power or more takes a few things, slipping while coming on pipe is one thing that's easily addressed but the damage that occur's from higher comp and clutch dump start's is far worse!The guide pins on these engines are mild steel and tend to bend when you have higher compression and do clutch dump start's then this elongates the holes in pressure plate and it wont disengage properly from hanging up on the bent guides.I've replaced those with hardened steel ones,replaced the stock spring with a 340 dodge valve spring at 360lbs and replaced the shear pin with hardened steel since I broke them with just to much preload on the stock spring,with the 360lb spring I have just over 5mm of the threads showing for preload.This with brake pads cut to fit works amazing and only slips if I want it to!The pressure plate being made of aluminum makes me think about those elongated holes and how much easier that would occur,It may not yet to be seen but I cant see this thickness of aluminum being harder than even the cheap china steel.

It's steel. The whole reason I bought it was out 7 or 8 stock pressure plates one almost covered the pads. Trying to get the plates flat wasn't worth my time anymore. Done wasting time and money on the stock plates.

He's talking about pedaling up to speed then dumping the clutch to start it. How do you start yours?
Well then yeah that would be considered dumping, I was thinking more of that fella in the clutch adjust vIdeo taking off from a stand still. I pedal twice and my engine fires up. But from a red 8 pedal to match the idle rpm.
