GFB Respons Adjustable Blow-Off Valve Diverter

The GFB Respons adjustable blow-off valve (BOV) diverter is a dual-port diverter valve from Go Fast Bits. It lets you set how much air vents to atmosphere and how much recirculates. That gives you an audible blow-off sound without the driveability problems that fixed-ratio atmosphere-venting valves can cause on turbocharged engines.

Key Features:

• Patented venting bias adjustment: Twisting the adjustment ring opens the atmosphere port while it closes the recirculation port. You can set any ratio from fully recirculating (quiet) to fully atmospheric (loud).
• TMS (Turbo Management System) technology: Designed to improve throttle response and speed up boost recovery between gear shifts.
• Spring pre-load adjustment: Lets you tune the valve's response.
• High boost capability: Rated to hold boost pressures of 100 psi or more.
• Adjustable sound: You can tune the valve to the amount of blow-off noise you want, or lock it in full recirculation mode.
• Australian manufacture: Built in Australia to ISO 9001 standards.

Fine-tuning the venting ratio helps you get blow-off sound while avoiding the problems commonly seen with fixed atmosphere-venting valves on cars with MAF sensors. These include check engine lights, rich running and stalling. The Respons suits drivers who want turbo response and boost recovery, with or without the noise.
