GFB VTA T9460 blow off valve Ford Focus RS Mk.3 350HP

VTA T9460 = DV+ Performance with Blow Off Valve Sound!

Note: This valve is suitable if a vacuum-controlled valve is installed directly on the turbocharger.

Due to the GFB TMS technology, no springs of different hardness are necessary for the respective boost pressures, the valve regulates itself.
The adjustment screw on top of the valve can be used to adjust the spring preload of the piston spring in order to regulate the opening time during load changes and thus achieve a better response.
This adjustment has no effect on the tightness of the valve!

The VTA valve has the same design as the DV+ T9360 - i.e. the same advantages - but with an additional opening so that the excess charge air can escape into the atmosphere and thus produce the well-known blow-off sound.

The original valves are already leaking from the factory, which causes a loss of power that is even more pronounced in performance-enhanced vehicles due to the higher boost pressure.

By installing the GFB DV+/VTA, this "hole" in the charge air system is closed and in this way the response behaviour and the retention of the charge pressure is noticeably improved.
In addition, the turbocharger is protected because it no longer has to work "against" the hole in the charge air system.
At the same time, the well-known "whoosh" sound is produced during the gearshift by releasing excess charge air into the atmosphere.
Other manufacturers offer a simple spacer to generate the blow-off sound, which is also installed under the original valve.
This produces a blow off sound, but does not solve the problem of the leaky original valve.
With the GFB VTA valve, both problems are eliminated at once!

Open diverter valves/blow off valves are not legal in the German STVZO.
