Or if we took off the supercharger what would the HP be for that engine???

Pro-stock is around 3hp per CI right now. Doing the quick dirty math with this particular engine is probably around 490-510 NA. It takes roughly 150hp to spin the Supercharger in this application. However without getting into a bunch of variables that's more of a S.W.A.G.(Scientific Wild ***** Guess)

There are a LOT of variables in a supercharged application to have a "normal" or "standard". Type off supercharger(roots, screw, centrifugal) size of supercharger and it's efficiency range, Engine and it's volumetric efficiency. Amount of boost(the measurement of back pressure in the system).

The better an engine is in NA form the better it will be in Supercharged form provided the type of fuel being used can support it.
