For those of you who have had their compression tested, what #'s did you come out with? Mods?

I'm curious what I should be looking for, because I am up 6,300ft above sea level, and I'm looking for some near sea level numbers.

Any and all help is appreciated.

 

compression should be around 200 or so psi per cylinder.

Hm.. so factor in the elevation difference, should be about 185ish.

Thanks for the response.

 

This 'target' compression your looking for is irrelevant. What your looking for is consistency through all four cylinders.

This is what I always thought, but was recently told that even if all cylinders were 160-165, the numbers are low, even though they are consistent.

 

Another major factor is how many miles are on the engine. Obviously, a new engine will have high compression numbers as the rings are fresh and so is the hone. An engine with high miles will generally have lower compression numbers. That doesn't mean it isn't healthy though.

Look for consistency.

Thanks for the information.
