compression questions

so i recently did a compression test on my car, dry test, open throttle and received some really high numbers and was just wondering how i found my compression ratio? or what kind of benefits im getting with it.

compression readings
Cylinder 1: 225
Cylinder 2: 215
Cylinder 3: 220
Cylinder 4: 220

also is there anything bad about having high compression (since i read somewhere that normal for our cars is like 180?)

oh and my car is a 1990 honda prelude with a B21A1 motor.

Re: compression questions

Compression numbers have ALOTTTTTTTT of variables; motor, condition of motor, temperature of motor, altitude of car, quality of the compression tester, temperature of ambient air outside, etc etc...



Which is why its more important to have all 4 cylinders be within 10-15% of each other, rather than going for the highest numbers possible.
