Smart kid, water/alcohol injection is a very good method of knocking down the intake temps on superchargers. I think i've seen peeps running that setup and some stepped up pulley S/C setups making very good numbers. Mostly you see that kinda setup on roorts type blowers. The centrifugal types can have I/C setups just like turbo's, tho those are a bit peaky/tempermental from what i've heard. The roots type will give you on tap power all the time.

Also with either form of F/I good tuning is key to the power and longevitity of the engine.

*edited* good info slow-n-low, but turbochargers and superchagers are 2 different items. Centrifugal type superchagers are belt driven same as roots, but are not connected directly to the head.

For examples of the 2 different types of superchargers, take a look at these

This is a Jackson Racing roots type S/C

This is a Vortech centrifugal type S/C
