GFB DV+ Low Profile Valve - EA839 3.0T / 2.9TT
2.9 V6 Twin Turbo Models require 2x Valves to be purchased.
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 Continental brand OEM diverter valves found in late-model VW and Audi vehicles.
Unlike the earlier generation diverter valves manufactured by Pierburg, the newer Continental 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 Continental diverter valve, 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
- Sharper throttle response
- Faster boost recovery after a gearshift or brief throttle lift
- Unrivalled longevity, backed by our Lifetime Warranty
- Improved Boost Holding
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.
