Blow Off Valves

The FA24 engine in the 2022+ WRX now uses an electronically controlled factory diverter in place of the pneumatic bypass valve found on all previous turbo Subaru engines. This is controlled by the ECU, and whilst it sounds like an advancement in technology, in some ways it is a step backwards. It may react to throttle closures faster than a pneumatic valve, but longevity and boost sealing is an issue with these types of valve because their valve mechanism is made entirely of moulded plastic. Importantly though, the factory electronic valve cannot open and close progressively – it’s either open or shut, resulting in less than optimum throttle response and drivability.
High Performance Diverter Valve with low-profile integrated solenoid. Offers sharper throttle response, faster boost recovery on gearshift, and improved boost holding

• Solves boost leaking and reliability issues, whilst improving throttle response. Includes low-profile integrated solenoid to allow fitment in tight locations.

The newly released T9380 is the latest addition to the DV+ range of diverter valves from GFB (Go Fast Bits). It is specifically designed as a complete replacement for the newer generation of Continental brand OEM diverter valves found in late-model VW and Audi vehicles.

DV+ Performance Diverter Valve, Faster, Stronger, Simpler, Better

• Improved boost holding. Sharper throttle response. Faster boost recovery after a gearshift or brief throttle lift. Unrivaled longevity, backed by our Lifetime Warranty.

Furthermore, these benefits won’t cost you the Earth! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer’s “solutions”), the DV+ keeps what works, and replaces what doesn’t. It retains the factory solenoid and ECU control to ensure simple installation and reliable operation.

Like all valves in the DV+ family, the T9382 offers significant benefits over factory-fitted electronic diverter valves – sharper throttle response, faster boost recovery on gearshift or brief throttle lifts, improved boost holding, and unrivalled longevity.
Where the T9382 differs from the T9352 DV+ is that it includes a low-profile integrated solenoid, rather than disassembling the factory diverter valve and re-using the solenoid. This is beneficial in cases where the factory diverter has aged to the point where it makes sense to replace the factory diverter entirely. The T9382 also has a lower profile than the T9352, meaning it can be installed on Mini N18 engine (for a much simpler installation than T9353), and on other Peugeot models where clearance was an issue.
This means the T9382 can be used to replace the factory diverter valve entirely rather than re-use the solenoid

Where the T9381 differs from the T9351 DV+ is that it includes a low-profile integrated solenoid, rather than disassembling the factory diverter valve and re-using the solenoid.
This means the T9381 can be used to replace the factory diverter valve entirely rather than re-use the solenoid, or its low height allows it to be used on cars where a lack of clearance would prevent the fitment of a T9351 DV+. Perfect examples would include the EA888 gen3 engine found in the 2013.5 VW GLI, any MQB platform with an IS38 turbo and/or an aftermarket intake, or the 4.0 TFSI from 2012-2017.

The Hybrid valve is back! In 1999, GFB’s first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands. By “staging” the two venting outlets, at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound
the Hybrid is a dual outlet valve for combined recirc and atmosphere venting, this system makes it possible to be used on cars with sensitive airflow meters.
