Procharger Big Block Chevrolet F1 12 Rib Supercharger System 1CX100-F1

This ATI/Procharger Supercharger Tuner Serpentine HO Kit includes an F-1, F-1A, or F-1D head unit for SBC & BBC Chevy Engines. Designed for early model carbureted or EFI Small Block or Big Block Chevy applications, this tuner kit requires a custom tune (not included), and does not include a programmer, fuel injectors, intercooler, or high-performance fuel pump. F-1 through F-1R kits feature 9” (F-1/F-1A) and 9.75” (F-1C/F-1R) volutes. These superchargers use a patented high-speed compound bearing design and ProCharger’s proprietary synthetic oil blend. Ultra-rigid, precision ground 9310 steel shafts and gears on super-precision, high-speed bearings transfer power to a CNC machined 7075 aluminum billet impeller, spinning at a 5.40:1 overdrive ratio. A/C is only available with serpentine accessory drive kits.
