What is a Vent-to-Atmosphere (VTA) blow-off valve?

A VTA blow-off valve releases excess boost pressure from your turbo system directly into the atmosphere. This creates the audible 'whoosh' sound that many people associate with performance turbocharged vehicles.

Why is this blow-off valve not CARB approved?

Vehicles modified with VTA blow-off valves may not meet California Air Resources Board (CARB) emissions standards. This means it cannot be legally sold or shipped to California.

What does the 50mm size mean for performance?

The larger 50mm diaphragm on this valve allows it to move more air more quickly than smaller valves. This can lead to faster response when you lift off the throttle and better management of boost pressure, especially in higher-performance applications.

Product Details

If you're running a turbocharged engine and want to hear that satisfying 'whoosh' when you let off the throttle, a blow-off valve (BOV) is what you need. This Garrett GVB-50A is a 50mm valve designed to vent excess boost pressure safely back into the atmosphere, preventing compressor surge and protecting your turbocharger. It's a well-built unit that many enthusiasts choose for its distinctive sound and reliable performance.

This particular model is a Vent-to-Atmosphere (VTA) type, meaning it releases the boost sound directly into the air, giving you that classic blow-off valve noise. The 50mm diaphragm is larger than many stock or smaller aftermarket valves, allowing for quicker response and better airflow management, especially on higher boost applications. Garrett is a well-known name in forced induction, and this valve reflects their experience with solid construction and a design that fits right into many custom turbo setups.

Keep in mind that this valve is not CARB approved and cannot be shipped to California. It's a popular choice for those building custom turbo systems where sound and performance are key considerations.
