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.

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!
