However, that WCR is so fast I seriously doubt the Evo3 can be faster. My JP full option is as fast as everyone else's motor but my WCR was faster than everybody else!
Jefferylin, do you plan on running 30% in your Evo3? I want to break mine in tomorrow as well, but it will be my first time running 30% and I've heard that I should shim the head by .10, I've also heard that I don't need to shim. I don't want to screw this engine up since it may be my last one for the season.
