Supercharger Specification Terminology

Gearcase
Std = Standard Gearcase, HD = Heavy Duty Gearcase. Heavy Duty gearcases include high-speed bearings.
Max Speed
Maximum recommended impeller speed (RPM - Rotations Per Minute). Recommendations are based on supercharger efficiency and gearcase configuration (Std/HD).
Max Boost
Highest boost pressure attainable at maximum recommended impeller speed (PSIG - Pounds Per Square Inch, Guage Pressure).
Max Flow
Maximum recommended airflow (CFM - Cubic Feet Per Minute). Recommendations are based on supercharger efficiency.
Max Power
Maximum estimated horsepower attainable within limitations of Max Flow and Max Boost. Due to our rating system, horsepower figures are a relative guide and not an absolute maximum. Horsepower data resulted from engine dyno tests and/or was extrapolated from compressor map data.
Peak Eff
Highest compressor efficiency per SAE J-1723 Standard.
Inlet OD
Outside Diameter of air inlet opening, for hose or sleeve connection
Outlet OD
Outside Diameter of air discharge opening, for hose or sleeve connection
Inducer Diameter
Inside Diameter of air inlet opening
Outlet ID
Inside Diameter of air discharge opening
