Compression Test Results

[Manuel Kasko]

Old thread

But I think your results are fine dude

Only worry when you start seeing things like 150 and then odd 130 etc

Just keep an eye on it

No one mentioned cams affecting results. More overlap = less static comp.

i got a set of tomei pon cams. seeing 110 across all 6. dry test only. tryin to figure out why its so low.

[AngryRB]

its because of the extra duration and lift of the cam, it makes them less efficient at low speed,

same as with massive cam's on a drag car, they find it hard just to idle .

Thanks very much for your reply, I hope that's it

Yeh the extra overlap creates that problem. More air goes out the exhaust valve then on a std cam setup, usually the more overlap the lower your compression results.
