ProCharger P-1SC Self-Contained Centrifugal Supercharger Head Unit - 825 HP - 1,200 CFM - 32 PSI Max Boost - Polished Finish - PC050A-xxx-P
The ProCharger P-1SC Self-Contained Centrifugal Supercharger Head Unit has earned its reputation as one of the most proven and widely used centrifugal superchargers in the performance industry. Built for enthusiasts who demand serious horsepower, dependable operation, and excellent street drivability, the P-1SC continues to set the standard for self-contained supercharger performance. Whether you're upgrading a modern muscle car, classic hot rod, truck, or custom performance vehicle, the P-1SC provides the airflow and efficiency required to make substantial power without sacrificing everyday manners.
Supporting up to 825 supercharged horsepower while delivering an impressive 1,200 CFM of airflow, the P-1SC combines proven compressor efficiency with a compact, self-contained design that eliminates the need to tap into the engine's oiling system. The result is a cleaner installation, simplified maintenance, and the durability that has helped make the P-1SC one of ProCharger's most successful head units.
Why Enthusiasts Choose the P-1SC
Peak horsepower is only part of what makes the P-1SC so appealing. Its efficient centrifugal compressor produces a smooth, linear boost curve that increases with engine RPM, helping deliver predictable throttle response, manageable traction, and excellent street manners. Unlike positive displacement superchargers that produce immediate peak boost, the P-1SC progressively builds power, making it a strong choice for spirited street driving and competitive motorsports.
The P-1SC is equally well suited for weekend cruisers, street/strip combinations, autocross builds, road race cars, and drag racing applications. Its broad versatility has made it a popular option for enthusiasts who want a supercharger capable of continuing to support their combination as future engine upgrades are added.
Engineered for Long-Term Reliability
Every P-1SC is constructed around a rugged 6061 billet aluminum gear case and features a precision CNC-machined 7075 billet aluminum impeller, precision-ground shafts, premium high-speed bearings, and ProCharger's proprietary self-contained synthetic lubrication system. Because the supercharger carries its own dedicated oil supply, installation is simpler than with traditional engine-oiled superchargers, while routine maintenance remains quick and straightforward.
The efficient radial compressor design is capable of producing up to 32 PSI of boost, allowing the P-1SC to support everything from mild street combinations to aggressive high-performance builds while maintaining strong efficiency throughout the RPM range.
