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 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

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 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.

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.

Go Fast Bits Mach 2 upgrade kits convert blow-off valves from recirculating to atmosphere venting. To vent the Mach 2 to atmosphere, you need to ensure the piston stays closed at idle and the recirc hose is plugged. The 5930 Atmosphere Conversion Kit includes a 30mm hose plug to block off the recirc hose, a trumpet to replace the hose outlet on the Mach 2 (not necessary for functionality, but makes the sound louder!), and a firmer spring. The Mach 2 is supplied with a softer spring that's suitable for recirculation venting or cars with idle vacuum of 18inHg or less. If the piston stays closed with the existing spring in the Mach 2, there is no need to swap it out. However, if the piston hovers open at idle even with the spring pre-load maxed, the firmer spring in this kit should be installed to prevent stalling or backfiring.

APR DTR8868 turbocharger systems are direct replacements for the EA839 3.0L turbo engine. These upgrades include matching software for various vehicles and mods, providing up to 620 hp (571 AWHP) and 422 lbs.-ft. of torque (572 AWT), depending on vehicle platform and fueling, all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even ethanol on the S4, S5, and SQ5 platforms with fueling upgrades. For dedicated race cars, the turbocharger is designed with plenty of headroom to go even further on your own. The APR Stage 3 software is designed to avoid hard-spiking in the lower RPM band or running on the edge of what the factory rods and pistons should handle. Particular attention was paid toward component protections for exhaust gas temperature (EGT), back pressure safety (EMAP), turbocharger discharge temperatures, and fueling system capabilities. As rising exhaust gas temperatures require more fuel, the system will lower lambda to cool EGT without taxing the injection system with excessive on-times. Secondary protections will limit output for safety. The HPFP software helps increase headroom without over-driving the pressure to the injection system. The need for limiting power under extreme prolonged use (like tracking the vehicle), is greatly reduced, and the optional upgraded HPFP dramatically increases ethanol output. Note: Specific software is required to use this system, and an upgrade from lower stage systems is included for various vehicles. Software compatibility must be checked before purchase as the software installs to your vehicle's factory ECU. Currently, software can only be installed by an authorized APR dealer. Software is available in two formats: for use with the stock HPFP or for use with the APR HPFP. Additional APR DTR8868 turbocharger systems features, items, and specifications include: * Does not require a core and no additional downtime * Designed to bolt to factory location with factory-style connections * German dual ceramic ball bearing center section eliminates failure-prone journal bearing design * Smooth and reliable operation with a better transient response * Upgraded compressor cover with matching A/R * Larger aircraft-grade, 6061 billet aluminum 88mm compressor wheel * Turbine housing cast with high-temperature 310 stainless steel * Turbine A/R matched to nickel-based super-alloy K418 high-flow 54mm turbine wheel * Each rotating group is VSR (vibration sort rig) balanced for reliable operation * Includes complete turbocharger with a calibrated wastegate actuator and diverter valve * All necessary single-install hardware, gaskets, and clamps * Intake system adapter provides maximum flow-through as optional upgrade for factory intake * ECU software upgrade designed for factory engine and remains emissions-compliant * Supports 91, 93, 100, and 104 AKII, and E60-E85 in North America * Supports 95, 98, 104, 108 RON, and E60-E85 everywhere else * Integrated DV (Diverter Valve) port with OEM DV included
