ProCharger Open Race Blow-Off Valve - Black with Aluminum Mounting Flange - 3FASS-004B
The ProCharger 3FASS-004B Open Race Blow-Off Valve is engineered for serious high-boost, high-horsepower forced induction applications where rapid pressure relief is essential. Designed as ProCharger's open race valve, this valve quickly vents excess boost pressure during throttle lift to help reduce compressor surge and protect your supercharger, intercooler, charge piping, and other critical induction components.
Unlike an enclosed bypass valve, the open race valve vents pressurized air directly to the atmosphere, producing the aggressive blow-off sound many racers and performance enthusiasts prefer. The 3FASS-004B features a durable black finish and includes an aluminum weld-on mounting flange, aluminum tube section, vacuum hose, port fittings, and mounting hardware, making it an excellent solution for custom fabrication and race-ready ProCharger installations.
Whether you're building a drag car, no-prep racer, street/strip machine, standing mile vehicle, or another high-performance forced induction combination, this genuine ProCharger race valve is designed to deliver dependable operation under demanding conditions.

Engineered for Maximum Boost Control
High-performance centrifugal supercharger systems generate substantial airflow, making proper boost control essential for both performance and reliability. The ProCharger 3FASS-004B responds quickly during throttle transitions, venting excess boost pressure before compressor surge can occur. This helps improve system durability while maintaining consistent performance during aggressive driving and racing conditions.
The supplied aluminum weld-on flange and installation hardware make this valve an excellent choice for fabricators building custom charge piping on ProCharger-equipped vehicles or other high-performance forced induction combinations.
