With industry unique features such as electronic adjustment and Turbo Management Adjustment (TMS) technology, performance enthusiasts can enjoy an easy modification that is actually proven to improve acceleration and response on turbocharged applications. All of the products on this page are considered universal fitment, designed to be adapted to custom applications and may need to be welded in some cases. Application specific bolt-on valve kits are available for many popular platforms and can found on the vehicle specific blow off valve sections of the JSC Speed website.


Mach 1

If you want 'em to hear you coming, this is the valve you want! The Mach 1 blow off valve is hands down the loudest valve available in the Go Fast Bits lineup when used in VTA mode, but can be converted to a full recirculation valve in minutes for silent operation when needed. The Mach 1 universal blow off valve comes with both the Mach 1 trumpet fitting for VTA or a universal adapter for recirculation operation. The Mach 1 can operate in 100% VTA or 100% recirculation only.

Swap from 'stealth mode' to 'scare small children mode' as easy as flipping on your stereo system! The Deceptor Pro II is one of those modifications that is sure to turn heads and raise eyebrows whether you are on the street, at the track or at your local car meet. Revised porting allows the Deceptor Pro II more airflow and venting bias while the new bore finishing process will ensure a lifetime of reliability. The universal Deceptor Pro kit has a 35mm base, 30mm outlet and it compatible with most GFB trumpet adapters. The Deceptor Pro II comes with all parts and wiring required for an easy install and direct bolt on for most vehicles.

Turbo Fuse (Overboost Protection)

Overboosting is a dangerous and possibly catastrophic chance you take whenever you modify your turbocharged car. A faulty boost controller, inaccurate boost controller or simply a damaged or poorly clamped hose can cause thousands of dollars in engine repair or replacement. The Go Fast Bits Turbo Fuse is exactly as it sounds, an accurate and instantaneous fail-safe to an unexpected overboost condition. The Turbo Fuse installs in minutes on any car with an existing bypass or blow off valve and in the case of an overboost condition, will shut off the intake manifold pressure to the bypass valve causing the valve to pop open and relieve all boost pressure. As opposed to traditional 'pop-off' valves that were nothing more than spring loaded relief valves, the Turbo Fuse operates on a 100% on/off status, rather than slowly creeping to the relief point before opening. While many turbocharged cars have electronic fail safe systems in place, in the world of modified cars these systems are commonly disabled using a MAP clamp or similar device. Even if left if in tact, factory electronic boost/fuel cuts can activate when damage the damage has already been done. Plain and simple, keep your car safer and sleep better at night with a Go Fast Bits Turbo Fuse!
