ProCharger F-1R-103 Self-Contained Centrifugal Supercharger Head Unit - 1,500 HP - 1,900 CFM - 38 PSI Max Boost - Polished Finish - PC338A-xxx-P
The ProCharger F-1R-103 Self-Contained Centrifugal Supercharger Head Unit is built for extreme-performance and serious racing combinations that demand substantially more compressor capacity than the standard F-1R. Rated to support up to 1,500 supercharged horsepower while delivering as much as 1,900 CFM of airflow, the F-1R-103 provides the airflow reserve required for demanding four-digit horsepower builds while retaining the installation simplicity of ProCharger's self-contained lubrication system.
Designed for engines producing approximately 450-650 naturally aspirated horsepower, the F-1R-103 is capable of generating up to 38 PSI of boost. Its centrifugal compressor builds boost progressively with engine RPM, helping provide controlled power at lower engine speeds before delivering impressive airflow throughout the upper RPM range when matched with the correct pulley ratio, fuel system, intercooling, and calibration.
Greater Compressor Capacity Than the Standard F-1R
The F-1R-103 is positioned above the standard F-1R for combinations that require additional airflow and horsepower capability. Compared with the F-1R's published ratings of 1,250 HP and 1,700 CFM, the F-1R-103 increases capacity to 1,500 HP and 1,900 CFM. It also uses a larger 4.25-inch inducer and 3.5-inch outlet hose connection to support higher airflow demands.
Its 9.75-inch volute, 4.05-inch inlet hose connection, 4.25-inch inducer, 6.00-inch exducer, and 3.5-inch outlet hose connection are optimized for high-volume airflow. A larger 3.15-inch outlet inside diameter further distinguishes this model from lower-capacity F-Series head units while supporting the airflow requirements of serious competition engines.
Self-Contained Lubrication for Simplified Installation
The F-1R-103 uses ProCharger's proven self-contained oiling system, eliminating the need for engine oil feed and return lines. Its dedicated 4-ounce oil supply reduces external plumbing, simplifies installation, and makes scheduled maintenance easier than with traditional engine-oiled centrifugal superchargers.
Reverse-rotation capability gives builders additional flexibility when designing custom crank-drive systems, bracket configurations, belt routing, and supercharger placement. This makes the F-1R-103 an excellent choice for drag racing, high-horsepower street and strip vehicles, marine applications, and custom fabrication projects.
Designed for High-Output Competition Builds
The F-1R-103 incorporates a 5.40:1 internal step-up ratio and carries a published maximum impeller speed of 72,000 RPM. These operating specifications allow the compressor to achieve the speeds required to support its impressive 1,900 CFM airflow capability.
