h22 compression test
I was wondering if anyone could tell me what numbers an h22 compression test should look like. and if that number changes when you add higher compression pistons? if anyone has there results i would appreciate it

avr. compression is 190-220psi, no your compresion will not change with pistons- your compr. ratio will change, a compression test tells you if your looseing compression.

Re: h22 compression test (boostedh22lude1)
so 190-220. how important is it that all four are exactly the same or is it ok if there off a little bit. and how much can they be off in that range. or is doing the compression test basically just give you and idea in general that ur engine is leaking or if an individual cylinder is leaking

uhh yeah ur compression does change with different pistons, if u have high compression pistons ur ganna have higher compression numbers, and lower compressions numbers with lower comp pistons.

you'll rarely see all cylinders with identical numbers. you want to have 10% difference (max) between your lowest and highest cylinders. for example, if your lowest is 180 and your highest is 200, your in good shape.
