ProCharger D-1 Centrifugal Supercharger Head Unit - 925 HP - 1,400 CFM - 32 PSI Max Boost - Satin Finish - PC041A-xxx
The ProCharger D-1 Centrifugal Supercharger Head Unit is engineered for enthusiasts who have moved beyond entry-level forced induction and demand the airflow required for serious high-horsepower street and racing applications. Supporting up to 925 supercharged horsepower while delivering an impressive 1,400 CFM of airflow, the D-1 offers outstanding performance for naturally aspirated engines producing approximately 300-500 horsepower.
Capable of generating up to 32 PSI of boost, the D-1 is designed to support aggressive engine combinations where increased airflow and high-RPM performance are essential. Whether you're building a street and strip machine, drag car, race application, marine engine, or custom project, the D-1 delivers the performance headroom serious builders expect from ProCharger.
Built for High-Horsepower Performance
The D-1 combines a large 9-inch volute with a high-capacity compressor capable of supporting significantly more airflow than smaller street-oriented head units. Its efficient centrifugal design produces a smooth, progressive boost curve that builds with engine RPM, providing excellent throttle control, predictable power delivery, and exceptional top-end performance.
Unlike ProCharger's self-contained P-series head units, the D-1 is an engine-oiled supercharger. It is designed to utilize the engine's lubrication system rather than carrying its own oil supply, making it well suited for demanding high-performance applications where continuous engine-fed lubrication is preferred.
Engineered for Serious Builds
The D-1 features a rugged billet gear case, precision-ground shafts, premium bearings, and a high-efficiency compressor designed to withstand demanding operating conditions. Its 4.44:1 internal step-up ratio and maximum impeller speed of 65,000 RPM provide the airflow necessary for powerful street and competition combinations while maintaining the durability ProCharger is known for.
