ProCharger A-1R Self-Contained Centrifugal Supercharger Head Unit - 150 HP - 450 CFM - 15 PSI Max Boost - Polished Finish - PC065A-xxx-P
The ProCharger A-1R centrifugal supercharger head unit is a compact, self-contained supercharger built 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 choice for installations where space is limited. Capable of generating up to 15 psi of boost, the compressor operates at a maximum impeller speed of 75,000 RPM. Its 4.11:1 internal step-up ratio allows the impeller to reach the speeds required for smooth, responsive centrifugal boost throughout the RPM range.
Equipped with 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 added flexibility when designing mounting systems and accessory drive layouts.
Built for Compact High-Performance Applications
The ProCharger A-1R is designed for projects that demand 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 engineered to maximize airflow efficiency while fitting space-conscious induction systems.
