GFB · CUSTOM BUILD

For your custom engine build

Boost control, external wastegates and fuel pressure regulators. Select by connections and system design; your selected vehicle does not confirm fitment for these products.

GFB — Go Fast Bits — offers different valve designs for different engine layouts. At VPP, each version has a clear manufacturer identity and its own application information.

Start with the connection

A hose-mounted 1.8T valve, an electronic TFSI diverter and an EA211 without a factory diverter require different hardware. The GFB range at VPP therefore uses individual manufacturer part numbers with their own applications. Selecting a valve means choosing its mounting arrangement as well as its sound.

Recirculation or audible venting

Mach 2 and DV+ return released air to the intake. Respons and DVX allow the balance between recirculation and atmospheric venting to be adjusted. VTA provides atmospheric venting: T9430 for the listed EA211 applications, T9481 for selected Pierburg installations and T9480 for the newer Continental connection.

On a MAF-equipped 1.8T, that distinction matters. Mach 2 T9125 retains full recirculation. Respons T9025 adds adjustable venting that needs to be set for the vehicle.

Which DV+?

T9351 reuses the original solenoid. T9381 includes its own solenoid in a compact assembly. That difference matters where intake clearance is tight or the original electrical actuator also needs replacement.

T9380 is intended for the Continental connection. Similar engine displacement does not make these versions interchangeable: compare the original valve and the listed application before planning installation.

Product and installation information together

Each GFB product page includes the manufacturer part number, operating principle, application conditions and an original product photograph. Original installation instructions are downloadable directly from VPP.

Browse our diverter valves and blow-off valves and select your vehicle to narrow the range. For a changed turbo or intake, VPP can help assess the combination. The valve actually installed on the car remains an important part of that check.

More choice for your valve setup

The Hybrid T9225 provides three configurations for suitable 25/25 mm 1.8T applications: recirculation, 50/50 or atmospheric venting. The Deceptor Pro II T9525 adjusts the balance electrically from inside the cabin. Both require correct installation and adjustment on a MAF-equipped engine.

For an electronic connection, compare VTA T9481 with the Pierburg DV+ or VTA T9480 with Continental DV+ T9380. Our DV+ versus VTA guide explains the differences; the chooser above shows the current product prices.
