ProCharger P-1R Self-Contained Centrifugal Supercharger Head Unit - 1,250 HP - 1,600 CFM - 36 PSI Max Boost - Polished Finish - PC055A-xxx-P
The ProCharger P-1R Self-Contained Centrifugal Supercharger Head Unit represents the next generation of ProCharger's legendary P-series lineup, pairing compact packaging with four-digit horsepower capability. Engineered for today's high-performance street cars, trucks, and race-inspired builds, the P-1R supports up to 1,250 supercharged horsepower while moving an impressive 1,600 CFM of airflow from a compact 9-inch housing.
Designed for naturally aspirated engine combinations producing approximately 300-500 horsepower, the P-1R bridges the gap between traditional street superchargers and dedicated race head units. Capable of producing up to 36 PSI of boost, it delivers the airflow and performance required for serious modern horsepower goals while retaining compact dimensions that can simplify installation in crowded engine compartments.
Built for Modern Four-Digit Horsepower
Horsepower expectations have changed dramatically, and the P-1R was developed to meet them. While 600 to 700 horsepower once represented an extreme street build, today's enthusiasts regularly pursue four-digit combinations. The P-1R is engineered to support those goals while preserving the compact packaging and installation flexibility that have made ProCharger centrifugal superchargers a favorite among performance builders.
With its advanced compressor design, optimized airflow characteristics, and efficient centrifugal power delivery, the P-1R generates smooth, progressive boost that rises with engine RPM. The result is excellent street manners, predictable throttle response, and exceptional top-end performance when matched with the proper engine combination and supporting components.
Compact Packaging. Serious Capability.
Despite supporting up to 1,250 horsepower, the P-1R retains a compact 9-inch volute, making it an attractive solution for applications where engine bay space is limited. The combination of a 3.75-inch inducer, 5.96-inch exducer, 4.00-inch inlet, and 3.00-inch outlet allows the P-1R to deliver substantial airflow while maintaining the packaging advantages enthusiasts expect from the P-series.
Like other ProCharger self-contained head units, the P-1R carries its own dedicated lubrication system, eliminating the need for engine oil feed and return lines. This simplifies installation, reduces plumbing complexity, and keeps routine maintenance fast and convenient.
Engineered with Genuine ProCharger Quality
Every P-1R is manufactured using premium materials and precision machining to withstand the demands of high-horsepower performance. A rugged billet gear case, precision-ground shafts, premium bearings, and ProCharger's proven self-contained oiling system work together to deliver the reliability enthusiasts expect from one of the industry's most respected names in centrifugal supercharging.
This listing is for the polished ProCharger P-1R head unit. Mounting brackets, pulleys, belts, crank drive components, intercoolers, charge tubing, bypass valves, fuel system upgrades, tuning, and installation hardware are not included unless otherwise specified.
