Mr. Coomer, are you serious 225-250+ cranking compression? I know lots of 8-sec. and faster cars and NONE that I have talked to crank in that range. Some are in the low 130-140 range. You racing a diesel?
Nope most any car out of the factory is 175-180 psi. Why would you think a race engine should be lower? I know some is lost due to cam profiles, but thats why they make dome pistons and closed chamber heads for I dont see how you can keep from it. Unless its a pump gas engine. I dont care how big the cam is either. Last wedge was at 16:1 and ran real, real good. But again I dont build pump gas engines. Last one was a 493 with Eddy heads, and the 590 MP solid...heck it had 180-190 IIRC If you build a engine with 13-14:1 compression expect it.. IDK what to say about the guys running 130 psi. I bet they would benefit in more compression or less cam I be willing to lay money on it that Randys will approach 200 psi.... 175+ anyways
