Exclusive “pilot-actuated” valve mechanism for
rapid response at high boost
The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. 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 on the next page.
Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus either a different solenoid valve to actuate the pneumatic valve or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install.
GFB’s DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/turbo flutter. Oh, and it doesn’t require different springs or frequent re-builds.
The DV+ Story: Better Performance – More Reliable
Common OE Problem #1
The diaphragm types are commonly known to rupture,
especially when boost and temperature are increased as a result of chip tuning.
Common OE Problem #2
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.
Additionally, in both cases, the solenoid on the OE diverter is directly connected to the valve mechanism, which is not ideal because neither it nor the return spring are strong enough to open and close the valve reliably at high boost.
With problems like this, you can see why other aftermarket manufacturers assume the best solution is to replace the factory diverter entirely. Unfortunately, though, whilst their replacement kits might be stronger than the factory diverter, their slower response speed and lower flow do not justify the extra cost and complexity – more of a compromise than a solution.
The DV+ addresses the factory valve problems with a very
simple and elegant solution. Keeping the factory solenoid retains all the
benefits of the stock system, and replacing the valve parts with indestructible
metal components ensures strength and reliability no matter how much boost you
run.
Go Fast Bits have designed the DV+ so that you can keep all the parts that do work and only replace what is no longer working.
GFB have extended there range of products with the DV+ which has been designed has a direct fit solution to replace the weak factory diverter valve which is used on many European vehicles.
The solenoid coil from the factory is a great working part that does a great job so there is no need to replace it, but the weak part is the plastic valve mechanism, GFB have replaced the valve mechanism with an anodised billet aluminium housing which is then fitted with a brass piston, this has been machined to exact tolerances which gives you sharper throttle response and lightening fast valve actuation, this is also able to hold as much boost as you can throw at it. The DV+ is easier to install and less expensive than other makes.
