compression ratio vs boost psi

[ZeForce]

It also depends on how you drop compression, by pushing the head away using a thicker head gasket or keeping the head close to the deck and using lower comp pistons.

This is a very good point, a lot of people are assuming 10:1 comp is the same no matter how it is a achieved.... the fact is combustion chamber shape does play a big part in burn efficiency and detonation resistance.

So you guys think my JAP spec B16A2 10.4 Comp on 10psi will blowup

We'll see soon I guess
