ProCharger Stage II Intercooled Supercharger Tuner Kit w/ P-1SC-1

A centrifugal supercharger kit using the same P-1SC-1 head unit as ProCharger's HO kit, mounted on the front of the engine off the belt and feeding air through an intercooler into the stock intake. This one is set up for a higher boost target.

why this one — About $400 more than the HO kit for a claimed 50 percent or better horsepower gain, so it is the pick when your target sits above what the HO kit delivers. The extra money buys boost, not convenience: it is still a tuner kit with no fuel system and no tune included, and it needs a PCM unlock plus dyno time before it will run right.
