Product Description
The Go Fast Bit BOV is a hybrid BOV that allows the system to be fully atmospheric or fully recirculated depending on what you're trying to achieve. If you want your BOV to make noise, this unit can be fine-tune to give you that atmospheric BOV sound without causing a CEL, stalling, or your MITSUBISHI EVO to run rich. Besides the noise, why else upgrade the stock MITSUBISHI EVO bypass valve?
The stock unit is known for leaking and having inconsistent boost pressure that will prevent your MITSUBISHI EVO to perform at its best. Moreover the GFB BOV can return the engine to peak boost up to 30% faster than the stock unit when shifting gears. Overall its a great mod to have for optimal performance.
Product Features:
* 33 MM Inlet / 33 MM Oulet.
* Up to 30% faster boost recovery on gearshift.
* Adjust the volume of your blow-off sound. Allows you to control the amount of air that is vented to the atmosphere, or recirculated back into the intake to control the venting sound based on driver preference.
* Get the blow off sound without the hassles. Even on sensitive MAF-based systems. You can achieve a vented blow-off valve sound without triggering a check engine light or other problems such as running rich or stalling.
* Hold unlimited boost pressure.
* Direct bolt-on kits.

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 summarized 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).
