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 |

My bottle was inside when I was still racing, but when I retired from racing and turned the car into a street hotrod I moved it. Thanks for the pics Steve that helps. I was thinking bottle placement in cabin to ensure driver is absolutely covered while engine and fuel gets second billing. Car means nothing if you are dead (IMG:style_emoticons/default/smash.gif) So single line up front to fuel cell, single dual direction nozzle for driver/passenger, and two nozzles with one for each of the carbs. Sound about right? Thinking on advice to go aqueous foam as it sticks and prevents flareups. If the car catches on fire will be going through the whole thing anyway so cleanup is already going to happen. Thoughts? |

If the car catches on fire will be going through the whole thing anyway so cleanup is already going to happen. Thoughts? The aqueous film forming foam - AFFF we called it in the Navy will not disperse like a gaseous agent will, but I think the volume required will need a larger bottle or tank. I've read about the hazards of Halon and stories of people losing consciousness from breathing in the halon but in a race car with no side windows, I was not concerned. I figured that I could hold my breath for 30-60 seconds while I extricated myself from the car. In that time the agent would disperse. My car has three zones - fuel tank, cabin, and engine. I've seen demonstrations of halon on a raging fire and it is impressive although reflash is a concern. Emergency egress is something that I practiced and timed so that I could increase my chances of survival in a fire. Of course a fire from a leak where you can stop and exit while deploying the fire system is one thing, trying to exit after a crash where you might be injured, on fire and not wheels on the ground is quite another. Wise not to scrimp on safety equipment including helmet, gloves, shoes, suit etc. |
