GFB T9003 Respons TMS Adjustable Blow-off Valve suits WRX 01-07

RESPONS TMS : SMARTER THAN A DUAL PORT BLOW OFF VALVE

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:

1. 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.
2. 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.

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.
