How can you tell if you have good compression on a motor???

besides doing a test...

just wonderng because I am a perfectionist, the car starts very strong and fast, does not use any coolent, does not use any oil. And also the dyno numbers are below and the curves looked very smooth. would you think that compression is pretty balanced? also there is 102k on the motor

A test is the only way I know of.

I know but a healthy motor with good comp starts up quick and does all the other above things right?

you can tell usually by looking at that right?

it will run smooth no stumbles hesitations. a good compression engine will have alot of power, and check the spark plugs, u can learn alot about ur car from them.
