coyote kid Posted September 30, 2013 Posted September 30, 2013 What is good compression in psi for my 2.5 I am doing a compression test this afternoon and I need a baseline ...
jimoshel Posted September 30, 2013 Posted September 30, 2013 115 PSI is a good reading. Not going into ALL the variables that will have an effect on it. Much more important than the value of the reading is the comparison between cylinders. They all should be within 10% of each other.
