Convert Static Compression Psi to... Does anyone know a way to figure out your compression ratio using the static compression psi number? I am ranging from 240 - 249 psi which seems very high. I have searched Google and can't find a way to do it. Thanks.

Do you have a pretty small cam, and were they flat top pistons?
You could also try a larger cam if its not already on the edge of your taste for driveability, although if it pings all the time its not very driveable. Can bleed off a bit of that cylinder pressure. Any possible valvetrain issue that might cause the valves not to fully open

Something doesn't sound right. I guess I will have to pull a head to verify the pistons becuase Lunati spec says -1cc flat tops NOT dome style which I would imagine would need to be in place to make compression numbers like that. How does intake centerline placement effect compression? Wouldn't the compression be unequal then from one side to the other? Probably a stupid question but a question non the less. Please advise. Thanks!

I would consider fatter mixtures, maybe water or alcohol injection? I think 12 to 1 comp. is highest ive seen any one claim with good tuning to run on pump gas, anyone here have more info?
