im wondering what pistons and cp ratios you high hp guys are running

 

Arias and 9.3:1

You're going to find the vast majority of high HP cars on this site to be on JE, Wiseco, Arias, or CP pistons, with compression ratios typically between 9:1-10:1. I like a good 9:1 ratio for a street car.

 

go for 9:1 or 9.5:1. any piston that boosted92 mentioned is good, but i personally like arias or wiesco.
