ProCharger F-1R Self-Contained Centrifugal Supercharger Head Unit - 1,250 HP - 1,700 CFM - 38 PSI Max Boost - Polished Finish - PC326A-xxx-P
The ProCharger F-1R Self-Contained Centrifugal Supercharger Head Unit is engineered for serious street and race combinations that require exceptional airflow, four-digit horsepower capability, and the convenience of a self-contained lubrication system. Rated to support up to 1,250 supercharged horsepower while delivering as much as 1,700 CFM, the F-1R provides the compressor capacity needed for aggressive drag racing, street/strip, marine, and custom forced induction builds.
Designed for engines producing approximately 375-550 naturally aspirated horsepower, the F-1R can generate up to 38 PSI of boost. Its centrifugal compressor builds boost progressively with engine RPM, helping maintain smooth low-speed drivability before delivering outstanding top-end power when properly matched to the engine combination.
High-Flow F-Series Performance
The F-1R is built for enthusiasts who have outgrown smaller F-Series head units and need additional compressor capacity without moving into ProCharger's physically larger race superchargers. Its published 1,700 CFM airflow rating and 1,250 horsepower capability provide the airflow reserve required for demanding four-digit horsepower applications.
A 9.75-inch volute, 4.05-inch inlet, 4.00-inch inducer, 6.00-inch exducer, and 3-inch outlet create an efficient airflow path for high-output forced induction systems. These larger compressor dimensions distinguish the F-1R from the F-1C while retaining packaging suitable for many custom installations.
Self-Contained Oiling Simplifies Installation
The F-1R uses ProCharger's proven self-contained oiling system, eliminating the need for engine oil feed and return lines. Its dedicated 4-ounce oil capacity reduces plumbing complexity while making installation and routine maintenance easier than with traditional engine-oiled centrifugal superchargers.
Reverse-rotation capability gives builders added flexibility for custom mounting brackets, crank-drive systems, belt routing, and unique installation layouts. This versatility makes the F-1R an excellent option for purpose-built race cars, high-horsepower street vehicles, marine engines, and custom fabrication projects.
Built for High-RPM Operation
The F-1R features a 5.40:1 internal step-up ratio and a published maximum impeller speed of 68,000 RPM. This combination allows the compressor to reach the operating speeds required to achieve its published airflow and horsepower capability as engine RPM rises.
When supported by the proper fuel system, intercooling, pulley ratio, and tuning, the F-1R delivers the airflow capacity needed for serious horsepower goals while maintaining the smooth, progressive power delivery ProCharger centrifugal superchargers are known for. Actual performance depends on the complete engine combination and supporting components.
This listing is for the polished ProCharger F-1R head unit. Mounting brackets, pulleys, belts, crank-drive components, intercoolers, charge tubing, bypass valves, fuel-system upgrades, tuning, and installation hardware are not included unless specifically stated elsewhere in this listing.

Frequently Asked Questions
How does the ProCharger F-1R compare to the F-1C?
The F-1R carries higher published ratings of 1,250 HP and 1,700 CFM while using a larger 4.05-inch inlet, 4.00-inch inducer, and 6.00-inch exducer. It is intended for builders who need additional airflow capacity beyond what the F-1C offers while retaining self-contained lubrication.
Does the ProCharger F-1R require engine oil lines?
No. The F-1R uses a self-contained lubrication system with a dedicated 4-ounce oil capacity, eliminating the need for engine oil feed and return lines. Always follow ProCharger's recommended maintenance and service procedures.
