Description
The main feature of the Cobb Tuning Bypass Valve is its unique tri-function design, allowing it to operate in three separate modes. Full vent to atmosphere, full recirculation, or 50/50 hybrid operation mode are user selectable and can be quickly reconfigured with standard hand tools. Full vent to atmosphere is possible by opening both the primary port and auxiliary port to atmosphere. Full recirculation is achieved by plumbing the primary output back into the intake pre-turbo with the auxiliary port closed. And the hybrid mode is also possible by pluming the primary port into the intake and leaving the auxiliary port open to atmosphere, causing much of the air to recirculate to retain driveability, while still creating an audible exhaust of some of the boost pressure.
The mounting flange, body, vent cover and piston are constructed of 6061 T6 aluminum, the spring seat is made from 303 stainless steel and the primary outlet is polished cast aluminum. O rings are used around the piston and on the mounting flange to ensure optimal sealing. The valve body is hard anodized for strength and corrosion resistance. The piston is dry filmed lubricated, providing enduring maintenance free service.
