GFB – DV+ T9366: Diverter Valve with TMS Advantage – JBM Performance

The new DV+ for Alfa Romeo Giulia 2.0L & BMW X5M/X6M (need 2 valves for X5M/X6M)! GFBƒ??S DV+ SOLUTION COULDNƒ??T BE SIMPLER ƒ??¶ÿKEEP WHAT WORKS AND REPLACE WHAT DOESNƒ??T.

• Uses factory solenoid coil for seamless integration
• Replaces plastic valve parts with metal for reliability and strength ƒ?? especially important on tuned engines
• Direct-fit replacement with GFBƒ??s TMS benefits
• Exclusive ƒ??pilot-actuatedƒ? valve mechanism for¶ÿrapid response at high boost

GFB expands the DV+ range with a direct-fit solution for the weak¶ÿfactory diverter valve used on many European vehicles.

The solenoid coil itself from the factory-fitted valve is great- the ECU¶ÿopens it faster than any pneumatic valve so why replace it? The¶ÿweak point however, is the valve mechanism itself. GFBƒ??s DV+ solves¶ÿthis problem by replacing the valve parts with an anodised billet¶ÿaluminium housing, fitted with a brass piston machined to exacting¶ÿtolerances.

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. Other manufacturersƒ?? products involve replacing the entire system with a traditional pneumatic valve, or include a solenoid valve with the diverter. These approaches add unnecessary cost and additional parts (in some cases requiring long vacuum hose runs, mounting brackets etc). All these additional items result in a product that is slower, less responsive, more expensive, and takes longer to install.

GFBƒ??s DV+ solution on the other hand is more responsive, less¶ÿexpensive, easier to install, and doesnƒ??t cause compressor surge/¶ÿturbo flutter. Oh, and it doesnƒ??t require¶ÿdifferent springs or frequent¶ÿre-builds either.

The DV+ Story: Better Performance ƒ?? 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;

• The diaphragms are weak and known to rupture, especially¶ÿif boost has been increased. Once this happens, the valve¶ÿwill no longer hold boost pressure.
• The plastic lip that surrounds the diaphragm is very thin¶ÿand pieces can break off, potentially ending up going¶ÿthrough the turbo.

Additionally, the solenoid on the OE diverter is directly connected to¶ÿthe valve mechanism, which is not ideal because neither it nor the¶ÿreturn spring are strong enough to open and close the valve reliably¶ÿat high boost.

With problems like this, you can see why other aftermarket¶ÿmanufacturers assume the best solution is to replace the factory¶ÿdiverter entirely, or change it to a purely pneumatic system.¶ÿUnfortunately though, whilst their replacement kits might be¶ÿstronger than the factory diverter, their slower response speed and¶ÿlower flow do not justify the extra cost and complexity ƒ?? more of a¶ÿcompromise than a solution.

GFB has taken a different approach to deliver a complete solution¶ÿthat solves existing problems and improves performance, without¶ÿcompromise or a hefty price tag.

The DV+ addresses the factory valve problems with a very simple and elegant solution. Keeping the factory solenoid, the DV+ retains all the benefits of the stock system. Also replacing the valve parts with indestructible metal components ensures strength and reliability, no matter how much boost you run.

Thatƒ??s not all; rather than using the solenoid to directly actuate¶ÿthe valve, weƒ??ve introduced a unique ƒ??pilot-actuationƒ? system. This¶ÿmeans the solenoid only has to control airflow through a small¶ÿpassage that is then used to open and close the piston (rather¶ÿthan opening and closing the piston directly), so it doesnƒ??t matter¶ÿhow much boost you push through it, the DV+ will open and close¶ÿreliably without ever exceeding the solenoidƒ??s capability.

This feature also improves on the factory system by opening the¶ÿvalve progressively in response to boost pressure, so it only opens¶ÿas much as required to get the job done (the factory valve simply¶ÿopens and shuts, it cannot partially open if boost pressure is low),¶ÿresulting in better throttle response.
