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 has 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 from a 2.3 Ecoboost Bronco, 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 intercooler piping rather than directly on the turbocharger. A plastic valve mechanism closing onto a plastic seat resulted in the largest OEM diverter valve leak weve seen yet at 28Lmin 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 T9384 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 theyre either open or shut. Your throttle, however, isnt. 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.
Unrivalled longevity, backed by our Lifetime Warranty
The combination of precision manufacturing, attention to detail, and robust materials mean the DV+ will last a lifetime. So does the warranty!
