Product Description

The Turbosmart TS-0204-1405 RacePort Plumback Blow-Off Valve (BOV) - Sleeper edition - is a universal performance turbocharger pressure relief solution designed for custom and high-boost turbo systems. Its Gen-V RacePort design delivers exceptional airflow in a compact, lightweight package roughly 50 % smaller and lighter than many conventional BOVs, making it ideal for tight engine bays and competition applications. The Plumback recirculation capability allows pressured air to be redirected back into the intake system quietly, maintaining boost stability while reducing vent-to-atmosphere noise.

Constructed from premium billet aluminum with advanced flow structures and boost-balance technology, this valve features a large 50 mm inlet for high-flow performance and a 38 mm recirculation outlet for efficient plumb-back operation. The quick-release V-band clamp and included fittings simplify installation into custom charge piping, while dual vacuum/boost reference ports provide flexible routing. Supplied with a pre-installed performance spring, the TS-0204-1405 is an excellent choice for race, track, or tuned street turbo builds where reliable pressure control and quiet operation are desired. Adapter flanges or custom piping are required to integrate with specific vehicle systems.
