    About 8 Psi and you should stay out of trouble.

    i'd only run standard boost which is 6 or 7psi on a non-intercooled one, and if its a hi comp model max about 10psi unless its tuned for more, but if its a turbo block should be able to handle 14psi if its tuned, keep it safe on 10psi with a front mount.
