this test was on a warm engine, btw some #'s might be a little off but not by much, should've wrote it down..is this still ok to turbocharge? i was just thinking about installing a thicker HG and ARP head studs...or should i rebuilt my spare shortblock w/ some used GTE pistons i bought awhile back...

cylinder 2: 170 psi
cylinder 3: 150 psi

Pole Position
most likely the valve seals which is recommended to replace during a hg change, when i did a cold compression test on my sc3 with 170k i cranked until it reached maximum psi on every cylinder which was around 180

lol...good question, it has about 306K..that's why i did a compression test to see if it's still strong enough to hold up on BOOST! i'll be the first to boost a overmiliege SC300 lol....btw do anyone knows if that thing called RESTORE at the autoparts helps restore compression?
