The GFB DVX Performance Diverter Valve is a fully recirculating direct replacement for the factory pneumatic diaphragm type BPV (Bypass Valve) that features GFB’s TMS technology, which can help the peak boost up to 30% faster over the factory diverter valve when shifting gears.
GFB have took the popular DV+ diverter valve and have added dual venting outlets along with GFB's patented Venting Bias Adjustment System. So not only do you get improved boost holding with throttle response, but you also have full control over the blow off sound volume!
GFB’s patented Venting Bias Adjustment System is the only one of its kind in the world. By using an internal rotating sleeve, the opening of both the recirculating port and the atmosphere port can be infinitely adjusted. This means that you are not stuck with a fixed 50/50 or 100% atmosphere venting ratio. As an additional benefit, because the atmosphere outlet is a single large port rather than a series of small holes, the venting sound is much deeper and louder than it is with a BOV spacer.
Other BOV kits eliminate the ECU control entirely, using pure manifold vacuum control instead. Whilst there’s nothing particularly wrong with this as that’s how the majority of BOVs work, ECU control is much faster and is able to detect & respond to much smaller throttle transitions.
Solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to “pilot actuation” to ensure better performance on stock or modified engines.
As for performance, because the GFB DVX features a carefully selected spring rate & spring pre-load adjustment, it can operate progressively to help sharpen throttle response. This is the basis of GFB’s TMS principle, which has been shown to reduce the time to peak boost on gearshift by 30%. This benefit is also particularly noticeable in situations where you are modulating the throttle to balance the car in a corner.
A easy direct-fit solution to the factory diverter valve used on many European engines.
Once installed, their will be sharper throttle response, lightning-fast valve actuation, and will hold as much boost as you can throw at it!
A true performance improvement, Increased boost handling ability, and a blow-off sound that is completely adjustable from factory-silent to ear shattering!
GFB DVX Performance Diverter Valve features:
- The DVX is not just a noise maker, by modifying the valve operation method it offers the same performance benefits that the GFB DV+ does
- No other blow off valve on the market allows you to alter the blow off sound simply by moving the adjustment lever!
- Retains ECU control for the fastest possible operation
- Built to last
A direct fit for:
