When the throttle closes and the intake system is under pressure, the high-pressure air entering the motor will bump into the closed throttle plate and a pressure wave will travel back to the turbocharger. As a result, the compressor wheel stalls and slows down very quickly resulting in premature bearings wear and shortened turbo’s lifespan. It means that the turbo will take longer to spin up the next time when the throttle is opened. A blow-off valve (BOV), or a vacuum-actuated valve designed to release the air to the atmosphere, releases pressure from the intake tract of a turbo car when the throttle closes.
Turbosmart offers you the Race port blow-off valve (BOV) that is redesigned from the Highest-flowing BOV and now features a unique collar design. It means the product is 46% lighter and 25% smaller than the product it replaces, while providing greater performance through faster turbo spool-up from idle and reduced turbo lag between gears. The product is designed for use on large-capacity turbocharger systems and high-horsepower engines. In addition, it's supplied with vacuum fittings, weld flange, and V-band assembly.
