ryan22laird Posted June 29, 2014 Share Posted June 29, 2014 What should the correct reading be on a compression test on a stage 2 forged engine ? A done a check today and all 4 cylinders are 110 psi over all 4 does that sound about right ? Forgot to mention it's wossner pistons if that makes any difference Quote Link to post Share on other sites
russ78 Posted June 29, 2014 Share Posted June 29, 2014 was this a cold test ? why did you do a compression test ? Quote Link to post Share on other sites
mikey4410 Posted June 29, 2014 Share Posted June 29, 2014 Thats not right at all.throttle must be fully open, each cylinder requires 5 secs of cranking to give result. All this with a WARM engine Quote Link to post Share on other sites
