GFB DV+ Diverter Valve to suit Volkswagen MK7 Golf R / Audi 8V S3 – T9359
AutoInstruct welcomes the Go Fast Bits (GFB) Diverter Valves to our range!
- Designed specifically for Mk7 Golf R and 8V S3
- Delivers DV+ performance benefits
- OE appearance
- Retains the factory electronic solenoid coil for seamless integration
- Replaces plastic valve parts with metal for reliability and strength on chipped engines
- Direct-fit replacement with GFB’s TMS benefits
- Exclusive “pilot-actuated” valve mechanism for rapid response at high boost
GFB expands the DV+ range with a direct-fit direct-fit diverter solution specifically designed for the VW Mk7 Golf R and Audi 8V S3 (2103-on).
Why fit a DV+?
The solenoid coil itself from the factory-fitted valve is great, but the problem is the plastic piston valve mechanism. The plastic piston-type leaks far more than most people realise (by design, not from wear), and doesn’t always close after a high-boost gear shift. So GFB’s DV+ solves this problem by replacing just the valve parts with an anodised billet aluminium housing fitted with a brass piston machined to exacting tolerances.
The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Read all about the DV+ story below.
The DV+ story: Better Performance + More Reliable
All late-model European cars these days are using ECU controlled solenoid-type diverter valves. This is a good concept because the valve can react very quickly and it only opens when it needs to.
However, there are some problems with these valves. Since they first appeared on VAG vehicles in 2006, there has been at least 5 different revisions owing to reliability issues. Without going into detail of the revision history, the latest revision C found on the Mk7 R and 8V S3 can still be improved upon. Whilst it is stronger and leaks less than previous revisions, it is still limited by its operating principle – being a direct solenoid operated valve, it can only operate in two states, open or shut. Unfortunately, cars don’t typically operate in two states – your accelerator isn’t a switch, and progressive relief of boost pressure during partial throttle closure is not possible with the factory diverter.
