The Twin Chamber Blow Off Valve is an adjustable, high-response unit for use on a wide range of applications. Rather than relying on the vacuum chamber alone, the Twin Chamber Blow Off Valve harnesses boost pressure in a second chamber to assist in opening the relief valve. This design allows the use of a unique flat-valve design, which provides excellent valve response under both low and high boost conditions without sacrificing flow capacity. Valve reaction is adjusted by tightening or loosening the spring tensioning screw on top of the unit. Blow off sound can be adjusted by turning the red collar at the base of the unit. With its innovative design and adjustment features, the Twin Chamber Blow Off Valve is flexible enough for use on street cars as well as racecars. Made in Japan.
