Turbosmart Kompact Shortie Plumb Back Blow-Off Valves

Turbosmart Shortie Kompact Series blow-off valves are specifically designed to suit aftermarket and upgraded factory turbos. Unlike standard plastic valves that use single-layer diaphragms (which are known to crack under increased boost), the new Kompact valves use an O-ring sealed piston; coupled with their billet aluminum construction, this allows them to support over 30 psi. These blow-off valves are available as universal models or as a bolt-on replacement for the factory valve on all BorgWarner EFR, KKK, and most Eco-boost turbos. The Kompact Shortie Plumb Back provides better boost response and greater boost handling capability.

Go Fast Bits VTA Performance Blow-Off Valves

Go Fast Bits VTAs are a performance blow-off valve solution for a wide range of foreign and domestic cars and trucks with an electronic factory diverter valve. If you want sound with your performance (or performance with your sound!), these VTAs offer just that! By combining the proven performance benefits of GFB's ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions. The VTA shares the successful DV+ design philosophy: "Keep what works, replace what doesn't." This means Go Fast Bits retained ECU control and the solenoid from the factory diverter to ensure the fastest possible response time—without the added and unnecessary cost of replacing the solenoid like some brands do. The weak part of the factory diverter has always been the plastic valve mechanism; this is the part GFB has replaced. The VTA features CNC-machined billet components that last a lifetime, and the valve operation method has been updated for better performance. The factory diverter valve can only operate in two states: open or closed. When it opens fully at low boost or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition. GFB pioneered the use of "pilot operation" in the DV+, which works by re-purposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve. It's this design philosophy that makes the VTA not only the best performing blow-off valve solution, but also the best value on the market. Order the VTA Performance blow-off valve model recommended for your vehicle. Key features: * TMS Technology for faster boost recovery on gear shift and during throttle modulation * Improved boost holding ability * Atmosphere venting for blow-off sound * Retains ECU control * Simple, direct bolt-on kits include everything you need to install
