Turbosmart TS-0204-1142 Black RacePort Blow-Off Valve

The Turbosmart GenV RacePort Valve is a competition-focused blow-off valve engineered for high-horsepower turbocharged and supercharged applications. Renowned for its compact and lightweight design, the RacePort is approximately 50% lighter and 25% smaller than many competing valves while delivering exceptional airflow capacity of more than 330 CFM, making it one of the highest-flowing valves in its class.

Designed specifically for vehicles already equipped with compatible female flange mounting systems, this version allows easy changeover from competitor valves without requiring a new weld-on flange. The valve features billet 6000-series aluminum construction, a quick-release aluminum V-band collar, hard-anodized internal components, and a high-temperature silicone Nomex diaphragm for outstanding durability under extreme boost and racing conditions.

The GenV RacePort utilizes Turbosmart's proven Boost Balance Technology and a positive-sealing valve seat to maintain reliable boost control while preventing leakage. With twin 1/8-inch NPT reference ports and support for optional valve position sensor upgrades, it is an ideal solution for serious motorsports, drag racing, and high-performance street builds requiring maximum airflow and dependable operation.
