Fire Supression Systems

Cold fire is good. I think a fire suppression system is overkill for a Raptor though.

That's probably what Chris Ross said....

a fire suppression system isn't overkill on anything you really care about

From my research when looking at a fire suppression system for my TT LSX RX7 TX Mile build.

"Halon (and the less environmentally hazardous equivalents) are great at putting out fires in confined spaces, but also great at severely jacking up human respiratory systems. Engine compartment maybe but never in the passenger cabin. In open spaces halon doesn't work either, it works by displacing the oxygen, so as soon as the hood/door/etc is open, oxygen gets back to the ignition source and it can light back up again. The film that AFFF makes smothers the fire, spreads out on fuel spills and floats as it's lighter than gasoline/diesel/etc so it stays covered, and cools the ignition source. We didn't call it "magic foam" for nothing, it can knock out a jet fuel fire in a heartbeat."

So after talking more with my chassis builder, we decided AFFF was the best way to go for safety and performance. Just be sure to get a nozzle pointed at your crotch as well, I hear that's a bad place to burn.

A fire suppression system that uses Halo as the extinguishing agent would be very bad in a confined space. Hell, I've used Halo to put out Aircraft fires on an open runway and still had a hard time breathing afterward because the oxygen being taken out of the air. I would never use Halo in the cab of my truck with fear of sufficating.

Really?! If that's all you can post in this thread why bother?

Find another way home you schmuck I already asked AII a question. Have you ever even used a centralized fire system in a crash situation?

When we are doing Shelby events, most cars that show up for track events carry a fire extinguisher if they aren't newbies. Its never happened at any of our events, but you typically don't carry an extinguisher to put out your own fire, you rely on those you are with to get it out while you focus on getting out of the vehicle. A few have a fire suppression system, but that's a small percentage.

I suppose it should be the same here with Raptors. Its a great idea to carry an extinguisher, which Trey has done a group buy for previously if I remember right, and we need to be ready to swarm if a fire breaks out -with caution.

Trey, do the Baja guys run fire systems, or just an extinguisher or two? If you aren't running five point harnesses, getting out should be fairly easy.

Prerunning we just run extinguishers.

The race trucks (at least ours) have a cold fire system. It's not to save the truck but to give the occupants enough time to get unharnessed and out. It's not easy crawling out of one.

Same theory as our cars. We have a halon system so incase of fire its pull the pin, deep breath, pound the button then get the eff out

I agree. Even though the reports state that t it's a myth that Halon actually removes the oxygen from the air, whatever chemical reaction it does do can make you damn near pass out. And passing out inside the cab or cabin of a burning vehicle is not the way to go which is you you go with AFFF in side the cabin. If you could just foam the entire vehicle that would be best, but if you ran two systems you could run Halon in the engine bay or on the fuel cell or fuel supply lines.
