Is 9.7to1 to high a compression for a 15psi boosted. if i stay n/a that is to low a compression aint it. what kind of horsepower do you think it might produce either way. any help would be very apreciated.

9.7:1 it a little hight for 15 psi, but if you have forged internals it should handle it.

Yes 9.7:1 is too low for N/A IMO.

A 15psi boosted 408 should put down some serious numbers man. I'm thinking 600rwhp+.

Its hard to say.

Low 500's maybe. Higher compression really helps with torque.
