Its questionable what it will do for you with the supercharger...intake manifolds typically don't yield much of a gain in N/A applications, but its a different ballgame when the air is being pushed through the system instead of drawn in. I would think you'd at least see a few extra HP/TQ at the wheels, if not more. The 2000 IM is supposed to be better-flowing than the later ones. You should definitely get a before and after dyno and see what it does for you.
