F-1X and F-2

Available for small block and big block Chevy engines, the intercooled and non-intercooled ProCharger F-1X and F-2 kits are the next step up the ladder from the popular F-1R. Utilizing a patented high speed compound bearing design, this supercharger offers 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 5.40:1.

Equipped with our 10.5” volute, this unit packs a lot of power in a package that will fit under most hoods. Utilizing a 6061 billet serpentine drive pulley, these blowers are custom configured for your application at no extra cost.

Want to turn it up on the weekends? No problem. With a wide range of pulley sizes available you can quickly change boost levels to suit your needs. The mounting brackets, like the transmission case, are constructed from 6061 billet, providing a solid foundation for your ProCharger. The drive system utilizes a 12-rib belt (cog option available) with a rugged manual belt tensioner and oversized pulleys that provide maximum belt contact for peak power output.

These kits also include a carb bonnet and the tubing required to boost your Holley 4150-style carburetor. The F-1X and F-2 utilize an advanced helixed impeller capable of accommodating a broad range of applications. The F-1X and F-2 are capable of supporting 1,400-1,600 hp on properly prepared small block, big block and LS-based engines.
