hi everyone i would like to know what is everyone's built bottom end compression test is at.. (psi) or what is the psi should be around with wiseco pistons with k1 rods.. when i 1st test my comp. was reading 140psi and it went up by 10psi when i did the wet test. i think any help would be great thanks

 

the main thing you are looking for is variation between cylinders. of course overall low numbers are not good but you will most likely see a very low number in a bad cylinder.

I have CP 8.5:1 pistons and a compression test will yield 150-155psi per cylinder

 

on my 9.0:1 cp i get 170psi. it also will depend on ring gaps.

 

all my cylinders were at 140psi.. i gap them for fi/turbo set up i guess 140psi is good.. thanks
