GFB - Go Fast Bits T9007 Respons Blow Off Valve BOV Diverter Valve

The GFB Respons blow off valve (BOV), also known as a diverter valve, is designed to improve throttle response and reduce turbo lag. It uses GFB's Turbo Management System (TMS), the term GFB applies to its diverter valves with features aimed at reducing turbo lag.

According to GFB's testing, TMS features can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.

The Respons also includes GFB's patented adjustable venting bias system, as found on the Stealth FX. It lets you vary the amount of air vented to recirculation or atmosphere, much like turning a volume dial. Fine-tuning the venting ratio lets you get a blow-off sound without the problems commonly associated with atmosphere-venting valves on cars with MAF sensors, such as a check engine light, running rich, stalling or increased fuel use.

Key Features:

• Advanced TMS turbo lag reduction features
• Spring pre-load adjustment for maximum response
• Full progressive venting bias adjustment, from recirculation (silent) to atmosphere (loud)
• Bias adjusted manually via the cap ring
• Can be locked off in full recirculation mode for legality purposes
• GFB offers the Respons in universal hose-mount and direct-fit configurations

Best choice for:

• Quick and easy venting bias adjustment
• Achieving blow-off noise on a car that is sensitive to atmosphere venting, such as VAG applications
