ProCharger D-1 Centrifugal Supercharger Head Unit - 925 HP - 1,400 CFM - 32 PSI Max Boost - Black Finish - PC041A-xxx-B
The ProCharger D-1 Centrifugal Supercharger Head Unit is built for enthusiasts who have moved beyond entry-level forced induction and need the airflow capacity 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 substantial performance capability for naturally aspirated engines producing approximately 300-500 horsepower.
Capable of generating up to 32 PSI of boost, the D-1 is designed for aggressive engine combinations where increased airflow and strong high-RPM performance are critical. Whether you're building a street and strip machine, drag car, dedicated race application, marine engine, or custom project, the D-1 provides 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 moving significantly more air than smaller street-focused head units. Its efficient centrifugal design creates a smooth, progressive boost curve that rises 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 engineered to use the engine's lubrication system rather than carrying its own dedicated oil supply, making it well suited for demanding 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 required for powerful street and competition combinations while maintaining the durability associated with ProCharger.

Frequently Asked Questions
What is the difference between the D-1 and ProCharger's self-contained head units?
The D-1 is an engine-oiled centrifugal supercharger, meaning it receives lubrication from the engine's oiling system instead of using a self-contained oil reservoir. This design has long been used in high-performance applications where continuous engine-fed lubrication is preferred.
Who is the ProCharger D-1 designed for?
The D-1 is an excellent option for enthusiasts building naturally aspirated engines in the 300-500 horsepower range who need a centrifugal supercharger capable of supporting up to 925 horsepower for serious street, drag racing, marine, or custom performance applications.
