I am new to the Jeep family and I was hoping the someone would be able to help me in finding a good super charger. Any information would be greatly appreciated.

Probably the best supercharger i've seen on the market is made by Avenger. Unfortunately it costs about $4000 and you have to modify your hood, but it is intercooled so thats plus. Accurate Power and Hesco also make superchargers.

look into building a 4.6l stroker motor using a 4.2l crank shaft and the 4.0l block should net you quite a bit of hp and much more tq and alot cheaper than a sc
