Spec Miata MX5, Autocross Comp test. Is my engine a strong one?

Spec Miata MX5, Autocross Comp test Learn a simple way to check your cars compression. Keep in mind the more compression you have the bigger your smile will be when you step on the gas. On a Miata you should have over 150lbs, anything lower than that, will cause your car to be low on power. Most cars are ok with anything over 100. If you perform the wet test and the compression rises significantly than you have a ring problem (engine overhaul time). If you do the wet test and it stays the same or only comes up a little you have a valve problem. Cylinder head rebuild.
