ProCharger F-1R-103 Self-Contained Centrifugal Supercharger Head Unit - 1,500 HP - 1,900 CFM - 38 PSI Max Boost - Satin Finish - PC338A-xxx
The ProCharger F-1R-103 Self-Contained Centrifugal Supercharger Head Unit is engineered for serious racing and extreme-performance combinations that require substantially more compressor capacity than the standard F-1R. Rated to support up to 1,500 supercharged horsepower while flowing as much as 1,900 CFM, the F-1R-103 gives racers the airflow needed for aggressive four-digit horsepower builds without sacrificing the installation convenience of ProCharger's self-contained lubrication system.
Designed for engines producing approximately 450-650 naturally aspirated horsepower, the F-1R-103 can generate up to 38 PSI of boost. Its centrifugal compressor builds boost progressively as engine RPM rises, helping deliver controlled power at lower engine speeds and hard-charging airflow through the upper RPM range when properly matched with the engine, pulley ratio, fuel system, intercooling, and calibration.
More Compressor Capacity Than the Standard F-1R
The F-1R-103 is positioned above the standard F-1R for combinations that need additional airflow and horsepower headroom. Compared with the F-1R's published 1,250 HP and 1,700 CFM ratings, the F-1R-103 increases capability to 1,500 HP and 1,900 CFM. It also uses a larger 4.25-inch inducer and 3.5-inch outlet hose connection, giving demanding race combinations a higher-capacity airflow path.
Its 9.75-inch volute, 4.05-inch inlet hose connection, 4.25-inch inducer, 6-inch exducer, and 3.5-inch outlet hose connection are sized for high-volume airflow. The larger 3.15-inch outlet inside diameter further distinguishes this model from lower-capacity F-Series configurations and supports the airflow demands of properly prepared competition engines.
Self-Contained Lubrication for Cleaner 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 head-unit maintenance more straightforward than an engine-oiled centrifugal supercharger.
Reverse-rotation capability provides added flexibility for custom crank-drive systems, bracket arrangements, belt routing, and supercharger placement. This makes the F-1R-103 suitable for purpose-built drag cars, high-horsepower street and strip vehicles, marine combinations, and other custom installations where packaging and drive layout are critical.
Engineered for High-Output Competition Builds
The F-1R-103 uses a 5.40:1 internal step-up ratio and carries a maximum impeller-speed rating of 72,000 RPM. These published operating specifications allow the compressor to reach the speed needed to support its 1,900 CFM airflow capability as engine RPM increases.
