zpi or nst supercharger pulley?

To learn just ask questions. Forums will answer alot of those questions, but be forewarned. Not everyone knows what they are talking about or you get only a partial answer sometimes. I suggest going to the library and checking out a few books. The Internet is a good place to start but the info is disjointed and hard to piece together for the whole picture. I learned the old fashion way by hanging out at the speed shops and helping my friends build their hotrods.

Do you want 200BHP or 200WHP? For WHP (Power at the wheels) in a N/A setup, you would have to go with 11:1 pistons, full exhaust 2.5" ID, CAI, Light crank pulley and flywheel. W/o an engine rebuild you would have to run a 25-50 shot of nitrous. 25 dry shot of nitrous would be perfectly safe on 93 octane gas. A progressive setup would be better and a wet nitrous even better.

I have the ZPI 9PSI pulley and have no complaints. Kenny (ZPI) had me source my 14.5PSI pulley from NST. Either one will work fine. It boils down to price and delivery.
