Mach 2 TMS Recirculating Diverter Valve – Compact 25mm Configuration

The GFB Mach 2 TMS Recirculating Diverter Valve is engineered to replace factory bypass valves in turbocharged systems where a 25mm hose size is required. Designed for reliability and performance, it improves boost response while retaining a fully recirculating, quiet operation.

TMS Technology for Improved Boost Response

GFB’s patented TMS (Turbo Management System) technology allows the valve to operate progressively in response to boost pressure. This improves throttle response and reduces boost recovery time after gear changes compared to conventional factory bypass valves.

Precision-Machined, High-Quality Construction

The Mach 2 features a precision-machined piston and valve body designed to maintain a consistent seal under boost. This ensures stable performance and reliable boost holding, even in demanding operating conditions.

Fully Recirculating for Smooth Drivability

As a fully recirculating diverter valve, this Mach 2 configuration retains factory-style airflow management. This helps prevent drivability issues such as hesitation or rich conditions that can occur with atmospheric blow-off valves on MAF-based systems.

Compact Size, Broad Application

With 25mm inlet and outlet connections, this Mach 2 valve is well suited to smaller turbo systems and applications where space or hose diameter is limited, while still benefiting from GFB’s proven TMS technology.
