GFB DUAL PORT BLOW-OFF
RESPONS TMS : SMARTER THAN A DUAL PORT BOV!
ATMOSPHERE VENTING BOV WONâ€™T WORK ON YOUR CAR? TRY A GFB RESPONS â€“ YOUâ€™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 GFBâ€™s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.
Why is this so important? Two key reasons:
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,Â even on a car with a sensitive airflow meter (MAF).
Hold on, it gets better. The Respons isnâ€™t just a noise-maker. It also;
Offers better throttle response
Faster boost recovery on gearshift
For example, using GFBâ€™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 GFBâ€™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.
Available in a huge range of universal and direct bolt-on kits
When we say â€śbolt-onâ€ť, thatâ€™s EXACTLY what we mean. Everything you need is included, it fits directly in the factory location (not on a separate adaptor), and no modifications to the car are required.
Performance AND sound without compromise!
Adjust the volume of your blow-off sound
Up to 30% faster boost recovery on gearshift
Get the blow off sound without the hassles - even on sensitive MAF-based systems
