Fire system

[P Clingman]

Hi all what fire systems are people using? 2 or 3 nozzle , halon or foam
Thanks Palmer

Sanctioning body rules will dictate the minimum number of nozzles you need. I have a halon system, but it's been in the car for many years. I don't know what the latest in fire suppression technology is these days. I don't remember if I got it from the local circle track parts place (Buddy of mine was the parts manager and could order me just about any standard racing parts I needed) or it might of been Pegasus.

John. There is no rule I could find in the PCA club racing rule book on number of nozzles

Here is the link to the SCCA General Competition Rules. Section 9.3.22 Page GCR-82.

They require 2 nozzles among other things. If you build to these rules, you should be good for anyplace you want to race (PCA, SCCA, NASA, POC). I'm confident that if you build to the SCCA safety rules for anything you are doing you should be safe, but double check the PCA rules just in case they are different if that is where you plan to race.

Just as a reference I happened to catch a segment on the NASCAR race last week. They have a 10LB system with nozzles for the driver and engine compartment. And another 10LB system and nozzles for just the fuel cell. This just goes to show how much it takes to knock down a fuel cell enough to get out of the car, because it won't put it out.

I checked my car and I have 2 nozzles, one for me and another that goes through the package shelf to point down to the top of the carbs, as that would be the most likely place for an engine fire.

I bought a foam one from I/O Port racing and will be installing it when it decides to warm up around here

I chose it based on my fear that Halon will be phased out (regardless of the claims of large surplus inventory, etc, I wanted to know I could have an easy refill in the future), and some fellow racers pointed out the foam will coat things to keep a fire from restarting and that you will be coated with it, which sounds bad, but actually becomes another layer of defense against being burned in a fire. I use a full-face helmet so no fear of getting in my eyes and such.

I considered running two smaller systems, one of each, but no real reason. I figured I would use the halon first as it requires no clean up. If it wasn't enough, pull the second, but I figure if I have a fire, a little clean up is the least of my worries.

I don't know much about the foam systems, but I understand your concern for future refills for halon.

Palmer,

The big advantages to the Halon systems are size and weight. Real important if you are racing - otherwise, of minor consideration.

I ended up buying a three nozzle foam system. I needed to add weight to my car to stay
in class so I went for the 3 nozzle 10 lbs system insted of the 2 nozzle.
Thanks for all your replys Palmer
