ProCharger Open Race Blow-Off Valve - Black with Steel Mounting Flange - 3FASS-008B
The ProCharger 3FASS-008B Open Race Blow-Off Valve is engineered for high-boost, high-horsepower forced induction applications where rapid boost relief is critical for both performance and reliability. Designed as ProCharger's open atmospheric race valve, it quickly vents excess boost pressure during throttle lift to help reduce compressor surge while protecting your supercharger, intercooler, charge piping, and other critical induction components.
Unlike an enclosed bypass valve, the 3FASS-008B vents boost pressure directly to the atmosphere, delivering the unmistakable blow-off sound favored by racers and performance enthusiasts. Finished in a durable black anodized finish, this genuine ProCharger race valve includes a steel weld-on mounting flange, short steel tube section, hose section, port fittings, and mounting hardware, making it an excellent choice for custom fabrication using steel charge piping.
Whether you're building a drag car, no-prep racer, street/strip machine, standing mile vehicle, or another serious forced induction combination, the 3FASS-008B delivers dependable boost management backed by genuine ProCharger engineering.
