Vortech Maxflow Race Blow-Off Valve - Black Anodized 8D204-111
Black Anodized Maxflow Race Blow-Off Valve for High-Performance Builds
The Vortech Maxflow Race Blow-Off Valve (PN 8D204-111) is engineered for high-performance forced induction applications that demand fast response, compact packaging, and a distinctive blow-off sound. Flowing 320 CFM at 8 PSIG, this Race BOV delivers excellent pressure relief in a compact form factor, making it ideal for vehicles with tight engine compartments.
While equally capable in performance to Vortech's Race Bypass Valve, the Race Blow-Off Valve features a 360-degree discharge design that produces a noticeably louder and more aggressive blow-off sound during throttle lift. This makes it a popular choice for enthusiasts who want both function and audible feedback from their boost system.
Maxflow Race Valve Design
The Maxflow Race Blow-Off Valve is preset to open at three to four inches of vacuum, ensuring rapid pressure relief and stable boost control during throttle transitions. Its compact, high-flow internal design allows it to outperform other valves of similar size while maintaining consistent operation under repeated boost events.
