Turbo XS Type H

Designed for high performance, the Turbo XS Blow Off Valve - Type H relieves compressor pressure surge caused by changing gears or backing off the throttle quickly. This valve is an extremely important part of any turbo system allowing quicker turbo spool-up between gear changes and greatly increasing the life of a turbocharger. The Type H provides greater venting flow than the Type S and is designed for turbo charged engines running 10 to 25 psi boost. Sizing of valve is based on flow and not boost pressure.
