SIRHCSHEE Posted May 5, 2004 Report Posted May 5, 2004 i was just wondering what kind of compression everyone was running im at 120 Quote
oldturtle Posted May 6, 2004 Report Posted May 6, 2004 My comp with stock motor was 105 psi at sea level so at this time my jugs and head are on their way to Patriot Racing in Sumner, Wash. for a bore, their hot trail spec porting, and their full head deck and squish fix for 91 oct Cal pump premium. I was very happy with the worn out motors power so this is gonna be like a dragster to me. Quote
Cotton eyed Joe Posted May 6, 2004 Report Posted May 6, 2004 i was just wondering what kind of compression everyone was running im at 120 Stock was 105 at 4500 feet. After the shaved head 135, and now after some porting its right around 150-155. Quote
