Compression test - what range values?

jmroy6

Compression values themselves are not as important as the % ranging between cylinders. i say this because you can get different reading with different gauges on the same cylinder. From my understanding these motors should be anywhere from 180-220psi on a wet or hot test depending on gauge and motors condition and a good rule of thumb is 10% between highest and lowest cylinder.

I just did a cold test on my motor and ranged from 160-170 psi with a range of 6% between my highest and lowest cylinder. Unfortunately i have not done a wet or holt test, but those number should only go up.

Husam2012 can chime in, i think he was reading 220psi on his new (Stock) motor.
