Ford Small-Block ProCharger F-1X Reverse Cog Race Kit

ProCharger 1FX223-F1X F-1X reverse cog race kit for carbureted or aftermarket-EFI Windsor/Yates small-block Ford engines using the 1985–1993 Mustang accessory arrangement. This describes the engine/accessory setup, not blanket stock-vehicle fitment.

Kit equipment

• F-1X supercharger in a reverse-mount / reverse-rotation configuration
• 8 mm-pitch, 75 mm-wide cog supercharger drive
• Race bypass valve included: specify open/closed, aluminum/steel flange and red/black finish
• No intercooler, intercooler tubing or carb hat included
• Alternator relocation and alternator-with-power-steering relocation kits are not offered for this reverse application

Configuration and pricing

Satin supercharger finish is standard at $8,748. Black adds $395; polished adds $500. The selected variant includes the supercharger finish; bracket finish, valve upgrades, optional Competition 4150 carb hat and fuel components are configured separately. F-series kits use straight-cut gears.

Engine and chassis fitment

Specify actual engine deck height, Windsor or Yates cylinder heads, chassis/VIN, crank/balancer details, induction and installed accessories. Confirm reverse-drive pulley alignment and clearance to the hood, radiator, chassis and custom plumbing. Provide target boost, engine RPM, fuel system, charge-cooling plan and tuner information. Carbureted installations require a compatible Holley 4150-style or similar blow-through carburetor and fuel-system upgrades, supplied separately. Performance depends on the complete build; no fixed boost or horsepower gain is promised.
