ProCharger D-1SC Self-Contained Centrifugal Supercharger Head Unit - 925 HP - 1,400 CFM - 32 PSI Max Boost - Polished Finish - PC051A-xxx-P
The ProCharger D-1SC Self-Contained Centrifugal Supercharger Head Unit brings together the proven airflow capability of the legendary D-series and the convenience of ProCharger's self-contained lubrication system. Supporting up to 925 supercharged horsepower while delivering 1,400 CFM of airflow, the D-1SC is built for enthusiasts who want serious horsepower potential without the added complexity of an engine-oiled supercharger.
Designed for naturally aspirated engine combinations producing approximately 300-500 horsepower, the D-1SC can generate up to 32 PSI of boost. Its combination of substantial airflow, compact packaging, and self-contained operation makes it an excellent option for high-performance street cars, street/strip builds, drag racing applications, marine engines, and custom performance projects.
Big D-Series Performance with Self-Contained Convenience
The D-1SC provides the airflow enthusiasts expect from the D-series while eliminating the need for engine oil feed and return lines. ProCharger's proven self-contained oiling system uses its own dedicated lubricant, helping simplify installation, reduce external plumbing, and keep routine maintenance quick and straightforward.
Its efficient centrifugal compressor develops a smooth, progressive boost curve that increases with engine RPM, providing excellent throttle control, predictable street manners, and exceptional top-end power when matched with the proper engine combination and supporting components.
Built for Serious Street and Competition Applications
The D-1SC uses a compact 9-inch volute, precision-machined internal components, premium bearings, and a proven 4.10:1 internal step-up ratio to efficiently support demanding horsepower goals. With a maximum impeller speed of 62,000 RPM, the D-1SC is engineered to deliver dependable performance for enthusiasts who expect both reliability and outstanding airflow.
Unlike the earlier engine-oiled D-1, the D-1SC gives builders the convenience of a fully self-contained head unit while retaining the performance characteristics that have made the D-series one of ProCharger's most respected supercharger families.
