Welcome to the Big Time! The ProCharger F-3 supercharger is the pinnacle for racers looking for ultra-high horsepower along with championship-earning reliability and consistency. The first centrifugal supercharger to power a doorslammer over 200 mph and into the 6’s, F-3 ProChargers are the centrifugal superchargers of choice among the best racers around the world. In fact, more racing championships and more world records have been set by racers running F-3 ProChargers than any other centrifugal supercharger. Period. Utilizing a patented high speed compound bearing design, these superchargers offer operating speeds unmatched by any other line of superchargers on the market. Lubricated with ProCharger’s own proprietary synthetic oil blend, the ultra-rigid precision ground 9310 steel shafts and gears (mounted on super-precision, high speed bearings) transfer power from the engine to a CNC machined 7075 aluminum billet impeller, spinning it at an overdrive ratio of 5.63:1–6.24:1. Equipped with our 12” volute, these units pack a lot of power in a package that can be fitted under most hoods with little or no modification. Utilizing 6061 billet serpentine drive pulleys, these blowers are custom configured for your application at no extra cost. The mounting brackets, like the transmission case, are constructed from 6061 billet, providing a solid foundation for your ProCharger. The drive systems utilize 8mm or 14mm cog belts along with a rugged manual belt tensioner and oversized pulleys that provide maximum belt contact for peak power output. This kit can be ordered with an intercooler, bypass valves and the tubing needed to boost your engine. F-3 ProChargers utilize advanced helixed impellers which accommodate a broad range of applications. With numerous trims available, our racer support staff can help you determine which F-3 model best suits your specific application.
