Looking to update a race car with a 3-bay suppression system. I have done this many years ago but looking for suggestions on ideal routing for the lines and bottle location. Car has two seats (although rarely used right seat) so may impact routing and will probably do a dual nozzle in the cabin to make sure any riders are covered. Will want to spray both banks of carbs in the engine bay and one nozzle for the fuel cell space.
Anyone have some good pictures of routing they have done and where to locate bottle so it is out of the way? Pull locations appreciated too. Thanks! Bill |

I don't think Halon is legal anymore with most sanctioning bodies. Certainly not with any around here.
Sounds like you've got the right thought - 2 nozzles @ engine, 1 @ fuel cell and 1@ driver. Not really any room against firewall to mount the bottle, especially if there's a passenger seat, so the bottle will have to be in passenger footwell. I've seen the pull handle positioned so emergency workers can reach from outside the car through a window. |

I've seen the pull handle positioned so emergency workers can reach from outside the car through a window. I think Halon is still legal. I just checked SVRA rules and they have no problem with it the replacement gas (Halotron?) is 50% as effective and requires twice the size of bottle to equal the same number of seconds of protection its still available for sale and for refill I do believe that manufacture of New Halon gas has been discontinued except for military use..... so the price went up... but its still available last time I checked. the foam type, water based systems have advantages in that they are easily refillable. But they are messy and subject to freeze damage too. all of the types of extinguishers have their advantages and disadvantages brant |

Halon is illegial to manufacture and hard to get, but available as of several years ago anyway (I had a hand held refilled locally). I understand they recover and reuse Halon these days - and yes it's not cheap.
@Brant - can you share more about how the cockpit nozzle causes issues with Halon? It is because it evacuates O2 from the cockpit? |
