Hi Guys,
We bought an off the shelf nitrous bracket and modified it. The bottle and bracket were listed at 7" dia. but the bottle was significantly under that so we have smaller rings in production now. The floor bracket picks up the front seat fasteners just like the fire bottle as Mark mentioned, and we picked up two fastens on the diagonal frame rail in the kick panel fuse area for the front of the bracket. The floor bracket is 1/8" alum with 3 welded tabs. 1/8" isn't really thick enough on its own to support the bottle weight especially considering the leverage it has on the flat floor bracket, but we needed it thin to hide properly under the carpet. The bracket isn't going anywhere due to the fasteners at each end, but to achieve the strength we needed in twist, we used a 3m double sided tape on the entire bottom side of the bracket.
The pluming comes in through the firewall near the AC lines. One -4AN feed line for nitrous to the motor, and one -8AN blow down line. The feed line routes along side the driver rocker with the rest of our custom hard lines for the IC, and the blow down tube is there to release the pressure of the bottle and its contents outside of the car should the burst disc blow. It routes through the front firewall and down to a fitting welded to the top side of the front belly pan, leaving a flat, flush hole in the bottom of the pan where the fitting would dump nitrous should it need to to prevent bottle rupture.
You can see the solenoids (nitrous to motor and purge) on the IC water tank between the IC inlet an outlet. The Nitrous solenoid is hardline to the IC outlet, just ahead of the DBW throttle body. The purge is hardline to the license plate frame, Mark has one of the billet Ford GT frames that had a camera pocket in the top... we machined it to take a LED and the purge line discharge. It will purge out the back and light it up blue. We'll see how it looks as soon as we get the bottle back in the car with the new rings.
Having the belly pan off to install this stuff above and the new turn signal LED bulbs, we took the opportunity to replace the bottom radiator shroud that I was never happy with. I have also attached images showing the lower radiator alum shroud we just built that matches the upper alum shroud we built a while back. The rubber OE shrouds are thin, leak air around the cores, and rip over time. This is a much better solution.
Cheers
