The supercharger should put you at about 450hp at the wheels based on your current engine setup...ie, nothing else done to it. That running at 6psi, which is the most our cars can run without an intercooler. If you get an intercooler, you can easily do 8psi, pushing your car to about 490hp. If that's the case, you'll probably need new injectors and especially a new fuel pump if you didn't already get one...i'm sure the kit came with one though. Since it is a SC, you could go LT's w/ ORY. That would in essence, add about what 1 extra psi would do from the SC. I'm looking to run a single turbo kit at 6psi, obviously no LT's though. SC kits are so expensive from the retailers!...$5k??? Turbo kits, although much more difficult to install I would think run under $3k! Besides that, your engine should be fine internally with the SC at 6psi and LT's. That should put you around 450-480 at the wheels, which allows for the limit our car's parts can go. Have fun...I NV U.
