Go Fast Bits Diverter Valve DV+ (Blow-off Valve) for BMW N55 engines

Go Fast Bits DV+ Diverter Valve expands the DV+ range with a direct-fit replacement for the weak factory diverter valve.  By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-oriented product that offers the following benefits:

• 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 GFB’s TMS benefits
• Exclusive “pilot-actuated” valve mechanism for rapid response at high boost

This Direct fit replacement for the factory diverter valve uses the existing solenoid with TMS advantage. Works with stock hardware, improves performance and reliability.

Exclusive pilot activation system allows HIGHER boost pressure. The end result is sharper throttle response, lightning-fast valve actuation, and the ability to hold as much boost as you can throw at it.

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.

Rather than using the solenoid to directly actuate the valve, GFB 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.

The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. 

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+ 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.
