Mach 2 TMS Recirculating Diverter Valve for Custom Turbo Installations

The GFB Mach 2 T9119 is a universal recirculating diverter valve designed for custom weld-on applications where a factory-style bypass valve is not suitable. Ideal for fabricated intercooler piping or bespoke turbo setups, it delivers reliable boost control without introducing atmospheric blow-off noise.

TMS Technology for Faster Boost Recovery

At the core of the Mach 2 is GFB’s TMS (Turbo Management System) technology, which allows the valve to operate progressively in response to boost pressure. This improves throttle response and helps the turbocharger return to peak boost more quickly after gear changes or throttle modulation.

Fully Recirculating for Smooth Drivability

As a fully recirculating diverter valve, the Mach 2 T9119 maintains stable airflow and factory-style drivability. This makes it ideal for MAF-based engine management systems where recirculated air is essential for correct fueling.

Designed for Custom Fabrication

The T9119 is intended for weld-on installations, making it suitable for custom intercooler piping and non-standard turbocharger layouts. Its compact design and robust construction allow it to be integrated into a wide range of custom performance builds.

Built for Reliability

Precision-machined internal components ensure consistent sealing under boost, while the serviceable design allows for long-term reliability in demanding turbocharged environments.
