The GFB DVX is more than just a noisy dump valve. It combines optimized performance, improved responsiveness, and a customizable blow-by sound. It's designed for those who want to get the most out of their turbo system without compromising reliability or the ability to maintain high boost pressure.
-
ECU Control: Much faster and more responsive than traditional pneumatic control
-
Sound adjustment: Easy and flexible adjustment of volume and type of discharge sound
-
Performance Enhancement: DVX doesn't just make noise, it also optimizes boost retention and throttle response, unlike spacers that don't correct performance deficiencies in factory systems
-
Increased reliability: Replacement of fragile factory parts with durable metal components
The DVX incorporates the proven benefits of the DV+, including improved boost retention and faster throttle response. It uses the pilot actuation method, which allows the valve to open and close more efficiently, especially under high pressure.
Adjustable Sound Control: With the patented vent bias adjustment system, you can adjust the proportion of air recirculated to the intake or vented to the atmosphere. This allows for fine control of the discharge sound: you can customize it to your preferences, ranging from quiet (100% recirculation) to a powerful, deep blast (atmospheric ventilation). This system outperforms simple BOV spacers, which limit flow capacity and do not correct the performance flaws of factory systems.
Improved Responsiveness: DVX retains the fast and precise control of the ECU (Engine Control Unit), allowing immediate detection and response to changes in throttle pressure. Unlike systems using only pneumatic control (by manifold vacuum), the ECU control is faster and able to handle fine and rapid throttle transitions.
Robust and durable design: As with the DV+, the DVX design uses durable metal materials (anodized aluminum and brass piston) to replace the plastic or rubber components of factory systems. This ensures longer life, especially on vehicles where boost pressure has been increased or modified.
Deep, Powerful Sound: Unlike BOV spacers that simply redirect air to atmosphere through small vents, the DVX features a large vent, resulting in a much deeper, louder discharge sound when the atmospheric vent setting is engaged.
