Well the main thing to watch out for when doing compression tests is the varry between cylinders should be no more then 20psi at most.

Higher compression means more combustion = more power

Hi Nicholas, search for compression in the search box (found on the left side of the page). There was a detailed discussion about this a month or so ago.

I agree with Mazda626, but for specific numbers, the discussion had some interesting statements.
