Description

MACH 2: 100% Recirculating Diverter Valve

THE SIMPLE & ESSENTIAL MOD FOR QUICKER BOOST RESPONSE

Utilising Proven TMS Technology to Ensure Dependable Boost Holding & Optimum Throttle Response

Blow off sound not to your taste? Want something as “sleeper” as possible? Don’t want your partner to know you’ve stuck a turbo on the daily (again)? Then the GFB Mach 2 is the valve for you!

Using GFB’s TMS technology the Mach 2 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below).

The Mach 2 is available in a range of universal and bolt-on kits for most popular turbo models. And when we say “bolt-on”, that’s exactly what we mean! No additional adaptors, parts or vehicle modifications are required – simply remove the factory bypass valve and replace it with the Mach 2 – it’s that simple!

The Mach 2 is configured as a 100% recirculating valve (i.e. bypass, plumb back) as a direct factory replacement, for when you want all the performance WITHOUT the noise!

Why replace the factory bypass valve? Better performance! Factory bypass valves typically have two main shortcomings – one is that they are often designed to blow open above a certain pressure to protect the engine (if you drive an EVO, take note and read this article!), and the other is they are not optimised for throttle response.

The Mach 2 solves both issues. With its pressure-balanced design, the Mach 2 can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response.

Factory diverter valves are commonly known to leak or fail, especially with age or higher boost levels. A GFB TMS will hold as much boost as you can throw at it, 24/7 - No frequent re-builds or replacement required.

Features

  • BETTER RESPONSE - Through reduced turbo lag - The GFB TMS is designed specifically to minimize lag - tests show that it can return the engine to peak boost up to 30% faster than a factory diverter when shifting gears, while delivering up to 40% more transitional boost (see GFB brochure)
  • BETTER DRIVEABILITY - Smoother than stock. Factory diverters tend to operate fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.
  • GET THE SOUND - OR NOT - It's your choice! Want noise? GFB patented Respons succeeds where others have failed! By adjusting the venting ratio of atmosphere/recirc, you CAN acheive a sound WITHOUT throwing a CEL, running rich, stalling using more fuel or causing other problems commonly associated with atmo-venting valves.
