Vortec Supercharger

[mtpockets]

On my BD #126, I'm running a Keith Craft 306 with a Holley 600, dyno at 305 rwhp. I have access to a Vortec Supercharger complete setup. I checked with Keith Craft and as long as I keep the boost at 10 or under I should be ok. I understand how it plumbs up with a fuel injection system. How do I go about setting this up with a carbureted system? Besides tightening up the seat belts a little more, making sure the life insurance is paid up and the BFG TA's not sticking very well, is there anything else I need to think about????
I have the need for speed.

That would be ultra-cool!!!!!!!! How much hp would you gain?

There are carbs designed for use with superchargers (flow through carbs).
The output from the supercharger is routed to the intake (top opening) of the carb and the carb is calibrated to accomadate the forced air flowing through it.

I have a few cars with superchargers on them including a Rotrex SC (23 lbs of boost), a Lyshom SC (18 lbs of boost), and a garrett turbo setup, but their all on fuel injected cars.

10 Lbs of boost would make a very worthwile improvement in horsepower, but I would suggest an intercooler setup which would make more power and be more predictable. One of my cars uses a water/air intercooler which is extremely efficient and lowers the intake air temperature dramatically (which makes more power and makes knock less likely, allowing for more ignition advance). The water/air setup doesn't require air to flow through an exchanger so it takes up less room and needs no air flow (no intercooler in front of the radiator).
