stockcar

if your talking about an compression test then it can depend on exactly how the test is performed BUT you should see similiar numbers acrosss all four and at a min i would expect it to be 130psi+

you cant recieve a reply for some reason.............

anyhows this will help

"i always do, then turn over for the same amount of time on each cylinder to allow the pressure to equlaise and hold the throttle approx 1/2 open
tend to disconnect the crank sensor to save any fire issues..............."
