    16psi on 2.8......

    Boost psi is JUST A NUMBER, the better the car flows the lower the number.

    So your car on a 2.8 wont make the same as mine on stock heads.

    Boost psi doesn't mean jack. Means even less if your comparing one engine to another.

    Why no headers? That's a interesting setup with that cam do plog/dp flows just as good as headers?
