Go Fast Bits SXV blow-off valves are designed to ensure the ultimate reliability, performance, and boost holding. Featuring a 25mm inlet and outlet, the SXV is the perfect valve to replace the plastic OEM bypass/diverter valve or integrate into a turbo system that didn't previously have a valve. Plastic hose-mounted OEM bypass valves are very common, as are the reliability issues they suffer from cracked plastic and diaphragm failures that result in significant boost loss and poor performance. A significantly leaking OEM valve can also accelerate wear or even damage the turbo from over speeding. These SXV blow-off valves utilizes an uncompromising approach to their design and materials to ensure all your hard-earned boost gets to the engine, so the turbo doesn't work harder than it needs to. Deliver your turbos' full potential with the use of these SXV blow-off valves featured from Go Fast Bits! Product Overview: * Precision CNC-machined components for rugged reliability * Viton piston seal for the ultimate boost holding * The operation of the SXV is designed to offer the best possible throttle * An OEM bypass/diverter valve is open until it needs to close—increases turbo lag * An SXV is closed until it needs to open—minimizes turbo lag * By venting only, when necessary, the SXV eliminates the additional lag imposed by the OEM valve, resulting in the best throttle response your turbo system is capable of delivering. * Switch out your OEM valve for an SXV for the ultimate reliability and throttle response, with the peace of mind of Go Fast Bits lifetime warranty!

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 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

Adding a blow-off valve to your Can-Am Maverick or Polaris RZR turbo system is a great way to improve throttle response and hear that awesome blow-off valve turbo sound. The purpose of a BOV is not just to sound cool, but it is designed to release the pressure that is built up in the charge side of the system. With nowhere to go, the pressure can cause turbulence to the impeller slowing the spool of the turbo down and causing premature wear. By installing a blow-off valve, you can improve boost response, prolong the life of the turbo, and of course, get that cool swoosh sound! The blow-off valves can be used in conjunction with the stock turbo inlet pipe or any aftermarket turbo hose pipe that has a 1 in. BOV flange. Since the factory valve is a diverter valve and this new valve is designed to be 100 percent vent to atmosphere, a high-temp push-on plug cover is included for the eliminated return hose. The valves are machined from 6061 billet aluminum then anodized in a stealth black finish, and the top is laser engraved with the Agency Power cursive logo and directions for adjusting. When the top of the valve rotates, this allows you to adjust the spring tension for your application. You can set the valve to easily vent off pressure or be stiffer to only vent at maximum psi. Key product features: * CNC-machined aluminum constructions * Anodized black * The top is laser engraved with the Agency Power cursive logo and directions for adjusting * With an ECU tune and higher boost levels, the BOV's can gain 10 to 15 percent more power over stock * Prolongs Turbocharge life * Great blow-off valve sound!

An all-new addition to the Turbosmart lineup is the fresh air Gen-V (Anti-Lag Valve (ALV40) for motorsport applications. They feature a 40mm valve diameter, a purpose-designed actuator housing—and multiple fittings for ease of fitment and fabrication. The anti-lag valve allows for incoming charged fresh air from the turbo to be diverted safely into the exhaust manifold pre-turbine wheel. With the throttle at low opening angles, this allows for safer spooling of the turbocharger—without the potentially damaging throttle-based late combustion anti-lag that can induce high engine stresses and break connecting rods. The ALV is a sealed twin chamber design, with the top port being the primary control port. The spring is designed to open under vacuum conditions to allow for the air to bypass into the exhaust manifold; while the lower chamber is for twin port control methods—to control the valve irrespective of manifold pressure. The shaft seal allows for leak-proof operation.

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

Give your automotive wastegate the proper "boost" it requires with a replacement diaphragm from Turbonetics. Wastegate valves are subject to malfunction when these key inner components of your turbocharger wear out. These diaphragms open the valve to divert exhaust gases away from the turbine; this, in turn, regulates boost pressure, while protecting both the engine and turbo. Turbonetics wastegate diaphragms are built with a silicone and Nomex fabric to resist cracking and splitting better than rubber, extending the performance life of the part.
