This beast is formally known as Vortech’s [(805) 247-0226; www.vortechengineering.com] new Maxflow bv57 bypass valve (PN 8D205-008; $436.95). This megaflow valve (1,300 cfm at 10 psi of discharged air) will completely and almost instantly clear an inlet of excess boost pressure when the throttle blade closes, regardless of its mounting position. We dig the gnarly V-band mounting clamp for leak-free sealing. This is one sick bypass that’s ready for big boost.
