I want to raise the compression on the z6 I am buiding for my rex from the 9.2-1 to 11 or 11.5-1. I have some a6 pistons that I want to throw in there, do you know what that will give me? Also how much of an increase will the SCE .043" copper gasket raise it?

Thanks
Andy

 

go to C-speedracing.com and they have a compression calculator. Type in what you got and it does the rest. Pretty acurate, to like .1 compression points
