Installation Instructions for GFB Respons (part # T9020) The standard inlet and outlet of the GFB Respons T9020 are 20mm in diameter, which is a suitable size for fitting into ¾” (19mm) I.D. hose. For different mounting options, a list of the adaptors available is found at the end of these instructions, but if in doubt, check out the adaptors page on our website www.gofastbits.com.au, or consult your local dealer.
Adaptors Available Base (inlet) adaptors: 5325 – 25mm hose base 5330 – 30mm hose base 5335 – 35mm hose/1” pipe mount base 5338 – 38mm (1.5”) pipe mount base Recirc (outlet) adaptors: 5225 – 25mm 5230 – 30mm 5233 – 33mm Spring Adjustment Contrary to popular belief, the spring pre-load DOES NOT need to be adjusted to suit different boost levels. The valve will stay shut under full throttle conditions regardless of boost pressure or spring pre-load.
Adjusting the Noise The unique patented venting bias adjustment feature on the GFB Respons lets you vary the amount of air vented to atmosphere or recirc, thereby changing the volume of the sound. Turning the venting bias adjuster (figure 3) fully anticlockwise means all the air will vent through the trumpet, which is the loudest setting. Turning the adjuster clockwise from this position will begin to open up more of the recirc outlet, until a ratio of 50/50 is reached.
