GFB‰ۡó»s DVX takes the extremely popular DV+ Diverter Valve̴Ì_and adds dual venting outlets along with our patented̴Ì_Venting Bias Adjustment System. So not only do you get̴Ì_IMPROVED BOOST HOLDING and THROTTLE RESPONSE, you̴Ì_have total control over your BLOW-OFF SOUND VOLUME!
WHAT MAKES DVX DIFFERENT TO ANY̴Ì_OTHER VALVE THAT GOES ‰ۡÌÝ̏WHOOSH‰ۡó�?
- The DVX is not just a noise maker (like BOV spacers) - by modifying̴Ì_the valve operation method it offers the same PERFORMANCE̴Ì_BENEFITS that the DV+ does.
- It retains ECU CONTROL for the fastest possible operation.
- No other blow off valve has the advantage of GFB‰ۡó»s Venting Bias̴Ì_Adjustment, allowing you to alter the blow off sound simply by̴Ì_moving the adjustment lever.
- Built to last.
GFB‰ۡó»s DV+ design solves the longevity and boost leaking issues that are̴Ì_common with factory diverter valves, and also changes the operation̴Ì_method to ‰ۡÌÝ̏pilot actuation‰ۡó� (read about this below) to ensure better
performance on stock or modified engines.
Furthermore, these benefits won‰ۡó»t cost you the Earth! Rather than throwing̴Ì_the entire factory diverter valve system in the trash (like other manufacturer‰ۡó»s̴æäÌÝ̏solutions‰ۡó�), the DV+ keeps what works, and replaces what doesn‰ۡó»t.
WHAT DOES IT FIT?
The T9659 is a duel venting direct factory replacement for̴Ì_the̴Ì_VW MK7 Golf R and Audi 8V S3
WHY NOT JUST USE A SPACER?
There are many ‰ۡÌÝ̏BOV spacers‰ۡó� on the market that make noise.̴Ì_However, they do this simply by using the factory diverter valve and redirecting̴Ì_the air to atmosphere. Therefore, the performance deficiencies̴Ì_of the factory diverter valve design remain, and furthermore, the flow
capacity of the factory diverter is significantly reduced because of the̴Ì_small venting holes used in these BOV spacers.
̴Ì_ECU VS VACUUM CONTROL
Other BOV kits eliminate the ECU control entirely, using pure manifold̴Ì_vacuum control instead. Whilst there‰ۡó»s nothing particularly wrong̴Ì_with this (that‰ۡó»s how the majority of BOVs work), the ECU control̴Ì_is MUCH FASTER, able to detect and respond to much SMALLER̴Ì_THROTTLE TRANSITIONS and, since it‰ۡó»s available, why wouldn‰ۡó»t̴Ì_you use it?
̴Ì_WHAT‰ۡó»S SPECIAL ABOUT OUR̴Ì_VENTING BIAS SYSTEM?
GFB‰ۡó»s patented Venting Bias Adjustment System is the only one of̴Ì_its kind in the world. By using an internal rotating sleeve, the opening̴Ì_of both the recirc port and the atmosphere port can be infinitely̴Ì_adjusted. This means that you‰ۡó»re not stuck with a fixed 50/50 or̴Ì_100% atmosphere venting ratio; you can change it to whatever you̴Ì_want! As an additional benefit, because the atmosphere outlet is̴Ì_a single large port rather than a series of small holes, the venting̴Ì_sound is much DEEPER AND LOUDER than it is with a BOV spacer.
̴Ì_THE BOTTOM LINE IS...
̴Ì_The DVX offers a TRUE PERFORMANCE improvement, INCREASED̴Ì_BOOST-HOLDING ability, and a blow-off sound that is COMPLETELY̴Ì_ADJUSTABLE from factory-silent to ear shattering!
