ProCharger A-1R Self-Contained Centrifugal Supercharger Head Unit - 150 HP - 450 CFM - 15 PSI Max Boost - Satin Finish - PC065A-xxx
The ProCharger A-1R centrifugal supercharger head unit is a compact, self-contained power adder engineered for lower-horsepower powersports and specialty performance applications. With support for engines producing approximately 50-95 naturally aspirated horsepower, the A-1R can support up to 150 supercharged horsepower while flowing as much as 450 CFM.
Its compact 7-inch volute and 3-inch inlet help make the A-1R a practical option where packaging space is limited. The unit is capable of producing up to 15 psi of boost and spinning to a maximum impeller speed of 75,000 RPM. A 4.11:1 internal step-up ratio allows the compressor assembly to reach the speed required to deliver responsive centrifugal boost as engine RPM rises.
The A-1R uses a self-contained oiling system, eliminating the need to route engine oil lines to and from the supercharger. It also supports reverse rotation, giving builders greater flexibility when designing a custom supercharger drive and mounting arrangement.
Built for Compact High-Performance Applications
The ProCharger A-1R is designed for applications that need meaningful airflow and boost capability without the physical size of a larger automotive supercharger. Its 2.28-inch inducer, 3.2-inch exducer, and 2-inch outlet hose connection are sized to support efficient airflow through compact induction systems.
This listing is for the satin-finish ProCharger A-1R head unit. Installation hardware, mounting brackets, drive components, pulleys, belts, intercooler components, tubing, bypass valves, and tuning are not identified as included unless specifically stated elsewhere in the product listing.
