ProCharger A-1R Self-Contained Centrifugal Supercharger Head Unit - 150 HP - 450 CFM - 15 PSI Max Boost - Black Finish - PC065A-xxx-B
The ProCharger A-1R centrifugal supercharger head unit is a compact, self-contained supercharger engineered for lower-horsepower powersports and specialty performance applications. Designed for engines producing approximately 50-95 naturally aspirated horsepower, the A-1R is capable of supporting up to 150 supercharged horsepower while delivering up to 450 CFM of airflow.
Its compact 7-inch volute and 3-inch inlet make the A-1R an excellent solution where installation space is at a premium. The compressor is capable of producing up to 15 psi of boost and operates at a maximum impeller speed of 75,000 RPM. A 4.11:1 internal step-up ratio allows the impeller to achieve the speed needed to provide smooth, responsive centrifugal boost as engine RPM increases.
Featuring a self-contained oiling system, the A-1R eliminates the need for external engine oil feed and return lines. It is also reverse-rotation capable, giving fabricators and custom builders greater flexibility when designing supercharger mounting systems and drive configurations.
Built for Compact High-Performance Applications
The ProCharger A-1R is engineered for projects that require impressive airflow and boost capability in a compact package. Its 2.28-inch inducer, 3.2-inch exducer, and 2-inch outlet hose connection are designed to maximize airflow efficiency within space-conscious induction systems.
