FAQ

 

How does a GFB Respons improve performance?

 

Boost Holding: Unlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn’t matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.

 

Throttle Response and Boost Recovery: GFB’s TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves, which can be summarised as: A factory bypass valve is open until required to shut.A GFB TMS valve is shut until required to open. This difference in operating methods means that the GFB valve only vents when required, and only enough air to prevent compressor surge. For example, during a gearshift it is possible to preserve a small amount of boost pressure for a short duration. Then, when the throttle is then re-opened, peak boost is reached faster than if all pressure is lost (as is the case with the factory valve that remains fully open too long).
