Go Fast Bits DV+ Diverter Valve Upgrade Kit (997 Turbo)
Designed to fit
- 2006 - 2008 Porsche 911 Turbo / Turbo S (997.1)
Note - includes 2 diverter valves upgrades, one for each turbo.
The GFB DV+ Diverter valve is a direct bolt on factory valve replacement. Designed to replace the weak plastic components in the diverter valves commonly found on European applications.
The factory BPV does not have the ability to open and close progressively in response to the existing boost pressure, and throttle response suffers when the valve vents more than it should in situations where you are not fully lifting the throttle. The T9354 solves these issues using proven metal and silicone construction of the valve components, meaning the DV+ will last a lifetime regardless of the harsh conditions.
The T9354 is a fully recirculating direct factory replacement for the pneumatic diaphragm type BPV (Bypass Valve) used on Ford, Volvo, Porsche, & Borg Warner Turbos – when you want the performance WITHOUT the noise!
Using GFB’s TMS technology can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears
The factory BPV (bypass valve) has a couple of key shortcomings, in construction and operation:
First of all, tuned engines running high boost also produce a lot of heat in the charge air. Because the BPV is situated right on the compressor, it is subjected to the hottest part of the intake charge, and the heat from the compressor cover itself. This can cause the factory diaphragm to rupture, and if that happens and goes undetected for a while, it can cause damage to the turbo, as the ECU will try to compensate for the lost boost pressure by increasing turbo speed.
Second, the operation of the factory BPV is not aimed at throttle response. Because of the soft spring and the solenoid valve that is in-line with the vacuum hose, it can only operate in two states – fully open, or fully shut.
About GoFastBits (GFB)
From John Adrian, Chief Engineer:
From the very beginning of my career, I’ve learnt that it’s amazing where tinkering can take you.
I’ve been engineering for 35 years, including 10 years manufacturing components for the automotive market including Original Equipment Manufacturers (OEM). I’ve been determined to push the limits of high performance engines since I was tinkering with my Mini Cooper S in the ‘80s.
When I bought my WRX in 1997, I decided to step it up a knotch and get serious. At first, I bought components ‘off the shelf’. Most of these were expensive and imported. Indeed, this was true for the Australian-made ones too. Nothing, however, came even close to the quality I knew they should be, as they were made of inferior materials and of generally poor workmanship, and did not give me the performance gains I was looking for.
So I started designing, testing and developing “GO FAST BITS”, a range of innovative and high-quality blow-off valves, boost controllers, pulley kits and short shifters. These products, unlike what was previously available, were meticulously designed and manufactured from the highest grade materials, working the way they were designed to.
Performance should not be about compromise – parts should fit correctly and deliver real performance outcomes, without making the car difficult to live with on a daily basis. GFB now has three qualified engineers (mechanical and mechatronic), and a team of dedicated enthusistic & passionate individuals who make the GFB name what it is today.
“GO FAST BITS” products are Proudly Australian, made in accordance with the ISO 9001 quality management system. Constantly we’re developing new, and innovative products.
