Go Fast Bits – DV+ T9380 Diverter Valve for VW and Audi applications

Description

The DV+ options for VW and Audi models!

The T9380 is the latest addition to the DV+ range of diverter valves from GFB (Go Fast Bits). It is specifically designed as a complete replacement for the newer generation of OEM diverter valves found in late-model VW and Audi vehicles. Unlike the earlier generation diverter valves, the newer generation valves cannot be disassembled and integrated into a DV+. Therefore, GFB developed the T9380 with a low-profile integrated solenoid as a complete replacement for the newer generation valves, enabling a hassle-free installation with no clearance issues.

Like all valves in the DV+ range, the new T9380 delivers the following benefits over the OEM diverter valve:

• Improved boost holding (see next page for more details)
• Sharper throttle response
• Faster boost recovery after a gearshift or brief throttle lift
• Unrivalled longevity, backed by our Lifetime Warranty

Improved Boost Holding

Since electronic OEM diverter valves first appeared in the mid-2000s, there have been many revisions over the years in an attempt to address reliability issues. Whilst the latest generation of OEM diverter valves have become more reliable, there is always a performance trade-off due to their operational method and plastic construction.

When GFB engineers performed boost leak testing on the OEM diverter valve in a VW Mk8 Golf R, they found the leak was significantly larger than in earlier generations.

This excessive leaking is due to the emerging trend of manufacturers mounting diverter valves remotely on plastic piping rather than directly on the turbocharger. A plastic valve mechanism closing onto a plastic seat resulted in the largest OEM diverter valve leak we’ve seen yet at 28L/min at 1 Bar of boost.

Even with the Viton face seal (featured on all DV+ pistons), the plastic OEM seat face was found to be so uneven that it was impossible to achieve a reliable seal. The T9380 successfully addresses this issue by incorporating an integral piston seat machined into its body. This design ensures a proper seal, even on uneven plastic OEM seats.

Sharper throttle response, faster boost recovery after brief throttle lift

Factory electronic diverter valves are binary in operation – they’re either open or shut. Your throttle, however, isn’t. When you make small throttle adjustments, the binary operation of the factory diverter results in abrupt changes in power delivery, which is the very definition of poor throttle response.

The DV+ patented “pilot actuation” system allows the piston to open and close progressively, thereby smoothing the power delivery during throttle modulation, and ultimately improving throttle response.
