Thread: compression test

I just did a compression test today and I got 130psi across the broad....what do you guys think about those numbers are they correct? I have a jdm de btw thanks

Sounds low, but even across the board is what you're after. You probably just missed a step. Did you warm it up? Hold the throttle open?

x2 warming up the car is key, and making sure you hold the throttle open, but doing a cold compression test can be a good test to do alot.

do you have cams? cams can effect compression too

Yea it was a cold compression test no cams what should my numbers look like across?

sr20de woud be good around 170 across.

i would do a warm compression test and see what you get

alright cool thanks again
