Product Description
The Garrett 914959-0002 GVB-50R 50MM Recirculating Blow-Off Valve (RCV BOV) in Blue is engineered for high-performance turbocharged applications requiring precise boost control, reliability, and fast response. Designed by Garrett Motion, this 50mm valve delivers superior pressure relief while maintaining optimal turbo efficiency and compressor longevity.
Unlike atmospheric blow-off valves, the GVB-50R features a recirculating design that redirects excess boost pressure back into the intake system. This helps maintain proper air-fuel ratios, reduces turbo lag between shifts, and ensures smooth drivability—especially on MAF-based systems.
Constructed from high-quality billet aluminum with a durable anodized blue finish, this valve is built to withstand high boost pressures and extreme conditions, making it ideal for performance street builds, track cars, and high-horsepower applications.
Key Features:
- 50mm recirculating blow-off valve (RCV) design
- Improves turbocharger longevity and efficiency
- Maintains proper air-fuel ratios on MAF-based systems
- High-flow design for high boost applications
- Durable billet aluminum construction
- Anodized blue finish for corrosion resistance and style
- Fast response diaphragm for consistent performance
Fitment:
- Universal – Compatible with most turbocharged gasoline and diesel applications
- Custom fabrication or adapter flange may be required
- Ideal for performance builds, street/strip, and racing setups
FAQ
What is the benefit of a recirculating BOV?
A recirculating BOV redirects excess boost back into the intake system, helping maintain proper air-fuel ratios and improving drivability compared to vent-to-atmosphere valves.
Is this better than an atmospheric blow-off valve?
For MAF-based systems, yes. It prevents rich conditions and stalling issues that can occur with atmospheric valves.
What size is this valve?
This is a 50mm high-flow valve designed for high horsepower and high boost applications.
Does this include installation hardware?
This valve typically requires custom piping or a compatible flange depending on your setup.
