What is the main benefit of the TMS Technology in this valve?

GFB's TMS Technology helps ensure rapid boost recovery when you shift gears and maintains good throttle response. This means your turbo stays spooled up better between shifts, leading to a more responsive engine.

Can I make this valve vent to the atmosphere for sound?

The Mach 2 is configured from the factory for full recirculation. While atmosphere venting kits are available separately, this specific model is designed for quiet, recirculating operation.

What vehicles does this diverter valve fit?

Product Details

The Go Fast Bits Mach 2 diverter valve uses a 25mm inlet and 25mm outlet, designed to handle boost pressures of over 100psi. This means it can hold more boost than most turbos can produce, ensuring your engine gets the air it needs. It's configured from the factory for full recirculation, meaning it sends the air back into the intake system rather than venting it to the atmosphere. This setup gives you the performance benefits of improved boost recovery and throttle response without the loud venting sound, making it a popular choice for those who want function over noise.

GFB's TMS (Turbo Mounting System) Technology is at the heart of the Mach 2, helping to recover boost quickly after gear shifts and maintaining good throttle response. This direct-fit, bolt-on valve is designed to cover a wide range of popular vehicles, including models like the Audi A4, Volkswagen Golf, and Saab 9-5. If you're looking for improved performance from your turbocharged vehicle and prefer a quieter operation, this recirculating diverter valve is a solid option.
