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.

Okay, yes, there are times you wish you could have that signature turbo blow-off sound, but not all the time. Go Fast Bits Deceptor Pro II TMS direct-fit motorized blow-off valves deliver just what you need—the ability to control how loud your BOV sound is, from the driver's seat. Featuring GFB's patented Venting Bias Adjustment System, coupled with remote electronic control, Deceptor Pro II units allow you to infinitely vary how much air is recirculated, and how much is vented to atmosphere. So, if your car typically suffers issues, such as backfiring and stalling when venting more than a certain percentage of air to atmosphere, the controller can easily be configured to limit the maximum venting ratio. This way, you can achieve a blow-off sound without having to put up with the issues. GFB Deceptor Pro II features and benefits: * Adjust your BOV venting bias electronically on-the-fly * Revised porting to optimize flow and venting bias * Compact design fits in most factory valve locations * Bore finishing process ensures a lifetime of reliable operation * Direct bolt-on for most vehicles available * Remote proportional venting bias/volume control- from silent to loud or anywhere in between * Sleek, compact in-car BOV volume controller with backlit dial * End-point adjustment to control maximum vent to atmosphere bias setting * Volume adjustment mechanism driven by a high-torque geared electric motor * Durable, low-friction gear train supported by precision sealed ball-bearing * Supplied with all parts and wiring required to have it up and running quickly and easily

Holley boost control solenoids are designed for optimal performance when using the boost control function of Holley EFI. Some setups require two solenoids and some require one. They're driven by a Pulse Width Modulated (PWM) output of the ECU. It is advised NOT to use the PWM+ outputs on a Holley HP ECU, but rather use the PWM- outputs. If you have a Holley Dominator ECU, use either the PWM- outputs or a PWM+ output on the J2B connector.
