Turbosmart Plumb Back EM upgraded diverter valves combine the SEMA Award-winning EM Vehicle Integration technology and tried-and-tested BOV5 architecture. Featuring a return hose for high-flowing plumb back performance and a direct-fit billet aluminum valve utilizing a 38mm / 1.5 in. positive seal piston, these valves will provide enough flow even for seriously modified vehicles while happily working on the factory and mildly tuned cars. The Turbosmart Patented EM System allows full integration with the factory electronics of later model vehicles. Some car manufacturers have taken to fitting electronic solenoid-actuated diverter valves—and have done this to use the valve for several other purposes outside the traditional use, such as when lifting the throttle, etc. EM Technology allows full integration with these systems and the motorsport-proven reliability and performance of a mechanical, piston-based valve. Additional details: * EM 'Electro-Mechanical full OE integration * True plug-and-play recirculating upgrade * 100 percent recirculating for OE integration * High-flow BOV5 design for high boost and upgraded power levels * 38mm /1.5 in. coated aluminum positive seal piston * Boost-balance valve technology * Black anodized for a low-profile, high-quality appearance * Black silicon hose return pipe

Go Fast Bits Respons TMS direct-fit blow-off valves with TMS Advantage allows you to infinitely vary how much air is recirculated or vented to atmosphere. Simply by twisting the adjustment ring, you can change the sound of your BOV from silent to ear-shattering! GFB's patented venting bias adjustment system can be tweaked between full recirculation (silent) and full atmosphere (loud). With the Turbo Management System (TMS) technology, Respons BOVs can return the engine to peak boost up to 30 percent faster than a factory diverter valve when shifting gears, offers better throttle response, and unlimited boost-holding. If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons valves can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues.

Go Fast Bits Respons TMS Universal blow-off valves with TMS Advantage are patented adjustable venting bias system diverter valves. GFB's Respons BOVs allow you to precisely control how much air expels from each of the two outlets, which is key for two reasons. First, you can adjust how loud the blow-off sound is--recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it anywhere in between to suit your preference. Second, you get a blow-off sound without causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF). And this is accomplished by simply twisting the adjusting ring. GFB's Respons TMS Universal blow-off valves are not just noisemakers. They also offer better throttle response, faster boost recovery on gearshift, and unlimited boost-holding. Using GFB's TMS (Turbo Management System) principle, tests show that Respons valves can return the engine to peak boost up to 30 percent faster than a factory diverter valve when shifting gears.

The Hybrid valve is back! Go Fast Bits Hybrid dual outlet valves are three valves in one; full recirculation, full atmosphere, or 50/50 venting. In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful, and the technology has since been adopted by most other brands. By "staging" the two venting outlets at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound--a benefit that makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound. Go Fast Bits Hybrid dual outlet valves are direct-fit, bolt-ons with a range that covers a huge list of popular vehicles. Purchase the Hybrid model for your vehicle.

Go Fast Bits SV52 blow-off valves are more compact and offer more flow. Standing only 86mm tall including the weld-on adapter, the SV52s have an astonishing boost pressure rating of 300 psi, and feature a monobloc body design, CNC-machined from a single aluminum billet that ensures strength without adding unnecessary bulk. They are designed with an anodized piston bore that creates an extremely hard and low-friction surface on which the single-piece aluminum 52.5mm piston glides and will continue to do so over countless cycles. The piston also provides strength and reliability, something a diaphragm cannot match in a high-boost BOV environment. Go Fast Bits SV52 blow-off valves include two springs, plus a spring pre-load adjustment system, so you can dial it in for optimum throttle response and boost recovery after gearshift, without resorting to the costly hit-and-miss approach of purchasing extra springs.

Protect your turbocharged engine from harmful pressure buildup. These Turbosmart diesel blow-off valve controller kits are designed to control the pressure signal to the blow-off valve. They work by detecting a negative voltage change in the throttle position. They then energize a solenoid to vent the air out of the blow-off valve cap, causing a pressure differential between the piston of the blow-off valve and the cap, which will vent pressure from the intake system. Kits include: * Specific race port blow-off valve * Blow-off valve controller * Wiring loom * Electric solenoid with bracket * Reinforced pressure tubing * Hose clamps * Mounting hardware
