ALL THE PERFORMANCE, WITH OR WITHOUT THE NOISE!
Give YOUR Kia or Hyundai the sound you want, and the performance to go with it!
The Respons TMS valves take the Hybrid dual-outlet concept a step further, featuring our Sound Adjustment System. This unique feature allows you to infinitely vary how much air is recirculated or vented to atmosphere, like a volume control. Simply by twisting the adjustment ring, you can change the sound of your BOV from silent to ear-shattering, or anywhere in between.
With over 20 years in the business of designing and manufacturing bypass and blow-off valves, GFB have learned a thing or two about managing boosted air, as well as the difference between a good blow-off valve, and a great one! Quality and performance are built into all GFB valves, which is why these products are backed by a lifetime warranty and offer the best possible throttle response and boost holding that any bypass or blow-off valve could deliver.
Unbeatable quality, direct bolt-on fit, exclusive sound adjustment system, lifetime warranty, AND a performance benefit – that’s what we mean by:
Performance Without Compromise
RESPONS TMS : SMARTER THAN A DUAL PORT BLOW OFF VALVE
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 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? There are 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, 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!
For example, 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)
How GFB’s 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 “bolt-on”, that’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.
