ryan22laird Posted June 29, 2014 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
russ78 Posted June 29, 2014 Posted June 29, 2014 was this a cold test ? why did you do a compression test ? Quote
mikey4410 Posted June 29, 2014 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
ryan22laird Posted June 29, 2014 Author Posted June 29, 2014 was this a cold test ? why did you do a compression test ?Yes mate the engine was cold and a only got the engine two weeks ago just wanted to see what the compression was reading Quote

russ78 Posted June 29, 2014 Posted June 29, 2014 try a warm test with throttle fully open buddy as mikey says as those readings are inaccurate.... Quote
