OK, I have a CT racing 440ex engine and the compression is 13.5:1 and runs on race fuel, it as loads of power but im not spending $3.00 a gallon on gas. what is the highest compression piston I can get away with on 93 octane below 4000 feet? Also, what is the best piston to go with? post a link if you know one that will suit my needs.
