Manufacturer’s Description:
RESPONS TMS : SMARTER THAN A DUAL PORT BOV!
Atmosphere venting BOV won’t work on your car? Try a GFB Respons – you’ll be surprised!
Just another dual-port BOV?
On the surface it may look like just another dual-port blow-off valve,but the Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.
-Adjust how loud the blow-off sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it ANYWHERE in between to suit your preference.
-Get a blow-off sound WITHOUT causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF).
Hold on, it gets better. The Respons isn’t just a noise-maker. It also;
Offers better throttle response
Faster boost recovery on gearshift
Unlimited boost-holding!
Using GFB’s TMS (Turbo Management System) principle, tests show that the Respons can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below)
(*Chart shows comparative manifold boost pressure rise during 1st to 2nd gear shift as tested on a CA18DET with a T28 turbo. GFB TMS improvement is seen as a 30% faster return to peak boost, during which time up to40% more boost is available)
How GFB’s patented venting bias adjustment works
Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between.
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).
