    How much max boost would you say she could take with-out blowing it up?

    And at that max boost whats your guess on HP?

    I would say 7lbs. is pushing it, but we're going to install Corolla rods, CP pistons and head studs.

    With bigger injectors upgraded fuel pump I see no problem with 280 to 300 HP
