ProCharger B-1 Self-Contained Centrifugal Supercharger Head Unit - 250 HP - 600 CFM - 20 PSI Max Boost - Satin Finish - PC064A-xxx
The ProCharger B-1 centrifugal supercharger head unit delivers compact packaging, self-contained lubrication, and performance capability for lower-horsepower custom applications. Designed for engines producing approximately 60-150 naturally aspirated horsepower, the B-1 supports up to 250 supercharged horsepower while flowing up to 600 CFM.
With a compact 7-inch volute, 3-inch inlet hose connection, and maximum boost capability of 20 PSI, the B-1 gives builders a capable centrifugal supercharger option for applications where space, airflow, and efficient power delivery all matter. Its maximum impeller speed of 110,000 RPM and 4.95:1 internal step-up ratio allow the compressor to generate substantial impeller speed as engine RPM increases.
The B-1 features a self-contained oiling system, eliminating the need to connect the head unit to the engine's oil supply. Reverse-rotation capability also provides additional flexibility for custom bracket, belt-routing, and supercharger-drive configurations.
Compact ProCharger Performance
The ProCharger B-1 is engineered for performance applications that need more airflow and horsepower capacity than the smaller A-1R while retaining the same compact 7-inch volute diameter. Its 2.28-inch inducer, 3.2-inch exducer, and 2-inch outlet hose connection provide the airflow path needed to support up to 600 CFM and 250 supercharged horsepower.
This listing is for the satin-finish ProCharger B-1 head unit. Mounting brackets, pulleys, belts, drive components, intercooler components, tubing, bypass valves, fuel-system components, and tuning are not identified as included unless specifically stated elsewhere in the product listing.
