Retains the factory solenoid coil for seamless integration
Replaces plastic valve parts with metal for reliability and strength on chipped engines
Direct-fit replacement with TMS benefits
Exclusive “pilot-actuated” valve mechanism for rapid response at high boost
A direct-fit solution for the weak factory diverter valve used on many
European vehicles.
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.
Our 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
Many late-model European cars use 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. There are typically two
types of solenoid-actuated diverter valves found standard on VAG and European
cars, both of which have their shortcomings.
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.
GFB has taken a different approach to deliver a complete solution that solves
existing problems and improves performance, without compromise or a hefty
price tag.
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 indestructable metal components
ensures strength and reliability no matter how much boost you run.
That’s not all. Rather than using the solenoid to directly actuate the valve,
we’ve introduced a unique “pilot-actuation” system. This means the solenoid
controls the air pressure that is used to open and close the piston, so it
doesn’t matter how much boost you push through it, the DV+ will open and close
reliably without ever exceeding the solenoid’s capability.
This feature also improves on the factory system by opening the valve
progressively in response to boost pressure, so it only opens as much as
required to get the job done (the factory valve simply opens and shuts, it
cannot partially open if boost pressure is low), resulting in better throttle
response.
Unnecessary Replacement Kits Are A Compromise, Not A Solution
