Product Description

The Turbosmart TS-0205-1300 Supersonic Blow-Off Valve is a universal, high-performance atmospheric valve designed for turbocharged engines where an audible and aggressive boost release is desired. Part of Turbosmart's Supersonic series, this valve features a positive-seal piston and tool-free cap adjustment, making it ideal for enthusiasts and racers who want both improved performance and a distinctive "whoosh" sound when releasing boost pressure. Its CNC billet aluminum body with blue anodized finish provides long-lasting durability and corrosion resistance.

Unlike recirculating valves, this Supersonic BOV vents excess pressure to atmosphere, enhancing the turbo sound while protecting your turbo system from compressor surge. The included quick-release V-band clamp and 38 mm weld flange adapter simplify installation in compatible turbo setups. Because this is a universal part (not vehicle specific), you must confirm that your charge piping and vacuum references match the 38 mm connections before installation. This BOV suits street, track, and competition use - but note that atmospheric venting may not be emissions-legal for controlled vehicles in all regions.
