Compression test results

[UnstableCable]

Is 9.2 bar (about 130psi) acceptable pressure across all cyclinders? Test was done dry.
Thanks

[chipis]

yes, its quite really good!

[Brigsy]

Not bad but not amazing, this is assuming your engine is standard compression. I see 150psi across all 4 on a dry test.

Yep 150 is what you're aiming for. Was that with throttle open and pump relay removed?

[UnstableCable]

Ah didn't think about that, it is a lower compression engine!

Throttle was closed and relay still in place! Will that make a big difference?

[clee]

Yes .
Throttle needs to be open to give you a true set of figures .

[SCHWARTZ]

With throttle open ul prob find it will be nearer 150psi, its good that they are all basicly the the same so no gasket or liner issues to worry about.
