RE: supercharging semi high miles

If I go FI, what should all the cylinders be around when I do a compression test? No thread stealing intended...

RE: supercharging semi high miles

I have always heard 125-150 is a good compression number per cylinder. I also read that as long as your lowest cylinder is withn 75% of the highest it is considered normal. I tested 2 cylinders today and had 130 in one and 140 in the other. When I get more time I am going to do the rest.
