Call me at Pegasus when you are ready for the fire system on the rebuild.

Bart,

Thanks I actually need systems for both race cars. Just too much at risk from this experience. Nothing more frustrating and heartbreaking to have 5 fire extinguishers on the car and the fire still blazing. No doubt if it was dealt with sooner it would not have gotten this bad!

Thanks,
Phil Grabow

AFFF systems are the way to go. They do require service every 2 years though, but when you need them they will smother the fire out and lay out a coat of foam to keep it from flaming up.
I always suggest a manual system due to the ease of use and service. If you set one off it wont cost you $300+ to get it refilled and recharged.
Awesome. Do you think 4L is a high enough capacity for the engine? Would you run a separate system for in car and what type?

Thanks,
Phil

Phil,

It's a really difficult question to answer. I think 4L is probably sufficient to put out an engine fire if the nozzles are well placed and the source of ignition (fuel/oil) is cut off. Whether 4L will provide a sufficient vapor barrier to stop re-ignition is another question. It's probably less than ideal, but these systems are sized as a compromise between capacity and weight. It's hopefully enough to allow for track support personnel to come with larger extinguishers. If you use that system, I would only use a few of the nozzles, so you get more volume of foam in the places where you really need it.

I think another in-car system is probably overkill, but it wouldn't hurt to carry a handheld extinguisher. CO2, halon, and FE36 are all no mess options, but none of them work well in a windy environment, or one where a source of fuel still exists (pool of gas on the manifold, etc...)

Just an opinion,

Duncan

Yeah I think I'll keep a hand held also for in car fires or as a backup for under the hood. What I realized in this case is that sometimes you can't make it all the way to a flag station.

In my case I think the fire got so out of control because we couldn't get the hood open to hit the source of ignition directly.

Ok, so if I were putting this system in my built time attack car it would be laid out as follows.

4 liter AFFF system using 5 nozzles

3 nozzles in the engine compartment:
1 high on the left by the fuel
1 high on the right by the electrical
1 high in the center of the firewall spraying the top of the engine.

1 nozzle under the dash spraying towards the firewall/my feet drivers side

1 nozzle by the fuel tank/ fuel cell assembly

I would run no less than the 3 nozzles in the engine bay as that is where most fires start. The idea would be to run the 3 nozzles up higher to coat the shiz out of everything when you put the handle. It will suppress the fire quickly, essentially cooling and coating everything with AFFF making it not flammable.

I'm thinking pointing two nozzles onto the headers (left and right) at that is usually the source of ignition, one towards the turbocharger and wiring harness and the other onto the manifold towards the fuel line.

For in car I think I'm going to rely on the handheld or I will get a smaller system for in car.

I'm really shocked the FRS blazed up so fast and at this point I can't really say what the source was or the ignition point. Fire was concentrated on the driver's side but the block had a hole in the passenger rear.

You should watch this video

It definitely works better with the hood closed. I wish the had the article up someplace from that test too.

It looks like the mechanical systems you have to pull the handle and continue pulling correct? Or is it a pull and get the heck out?

We use AFFF and halon as extinguishing agents onboard all seagoing military vessels. AFFF works great at putting out class B (flammable liquid) fires, and it doesn't damage electronics by itself. The type of AFFF we use can break down into H2S at high temperature, but that isn't really a concern in a track environment. I can say from personal experience that I would trust my life to AFFF and halon.

The definition says the words are interchangeable, except when referring to a sailor. What was your peeve?

It's two words. On board, not onboard. Aboard is preferred.

AFFF systems are the way to go. Very frustrating fire and the airbag at the end is just a final blow by the car to seal the deal lol
