Description: WORKS has teamed up with Go Fast Bits to offer Evo enthusiasts this unique recirculating compressor bypass valve which allows the user to adjust how much air gets vented to atmosphere for that oh-so-cool “Pssssssh!” sound that some turbo owners must have. Previously, Evo owners experimenting with venting a blow off valve to atmosphere ran into idle and drivability issues when the VAF equipped Evo evacuated all of its boost pressure to atmosphere. Now, because the WORKS/GFB DVV valve allows the user to vent some of the boost to atmosphere, and recirculate the remainder into the intake (16 positions), these drivability issues can be dramatically minimized or avoided altogether. We have found that venting only part of the excess boost to atmosphere will provide a good compromise of performance and sound to the Evo Enthusiast looking for the appearance, durability and sound of a quality compressor bypass valve, but not willing to compromise on overall drivability. Comes with GFB and WORKS instructions and preset to WORKS' recommended settings. Price: $339, WORKS Price $319. Silver, Blue, Red, or Black Availability: In Stock
