RE: how much boost

Dont quote me on this but I think 9psi becauseabove 9psi you need to change internals to handle the added power. Ever thought about upgrading your intake?

RE: how much boost

He's talking about the intake manifold, not the bottom end. There is no safe rating for the intake manifold, they crack because of the coolant temperature difference. I think 14psi is fine.
