Bloody old thread. 
What is the biggest size extinguisher these brackets can hold?
If the biggest are as dinky as what's imaged in the thread, then you're wasting your time.
Those little extinguishers would struggle to put a cigarette out, never mid an engine fire!

I've got a 1.75ltr lifeline bolted on mine and a 4ltr plumbed in system.
I think you could go with bigger than the 1.75 though mate.
Agreed, those flamebeater things wouldn't stand a chance in a fire. I think it's almost dangerous to sell them. Basically giving someone the idea that they would make a difference is to my mind misleading!

Rallying , they only recommend that the AFFF extinguishers are only enough to give you time to get out of the car , the big question is what happens if your trapped and you cannot get out
About the only extinguisher that will put a fire out , and which we used to use in rallying was Halon , but they deemed this was too damaging to the ozone layer so banned them for most people , as if the smoke given off a car burning car isn't worse !
Apparently the only places you can use halon now is on aeroplanes , the military or in the channel tunnel , but it doesn't stop anyone else buying one

Its 10 times the price of the AFFF handheld ones , I guess its how much of an insurance you want if the worst happens
The talk is Halon puts fires out AFFF probably wont !

Yes but halon in an enclosed cockpit will also asphyxiate a trapped driver Ian.
Agreed its better for putting a fire out but you will also be dead in the process.
I'm aware even what I have may not save my car, but it may save my life... One of which is more valuable to me than the other.

As the fire in a car will no doubt start under the bonnet you will have more chance putting it out with a halon one , the AFFF are crap , been there and tried them !
If I was ever trapped in my car , i'd rather asphyxiate than burn to death ! , well i'd rather neither but !
Its lucky that not many people actually get trapped in rally cars when they crash as they don't deform like a road car would , so you will have a chance to get out and fight the fire.
I'm sure I have read that halon evaporates when its come into contact with fire as well.
I mean , how more confined can you be than in an aeroplane , I'm sure if an extinguisher is the only one recommended for an aeroplane , then it will be the best available
Halon displaces oxygen which is why its so good at putting our fires , AFFF just smothers it , so will only work properly on a flat surface and you spray enough on top of whats burning.

So like you said, in a road car, halon is not advised.
Steve, not selling them mate. Dspeed used my design years back to make them. My one is billet alloy, his were coated steel.
Not difficult to make though.

I'm not saying you're wrong but aeroplanes have individual oxygen masks too.

I didn't say they were not advisable on a road car , I would advise them as it will be the best chance you have of putting a fire out I have the 360 extinguishers in my gravel car , one of the rallies I did this year , the Nav accidently set it off by mistake , and all it did was leak a clear liquid out of the valve on the bottle onto the floor ! Sent it back and they claimed it was working fine and charged me nearly £200 to fill it back up , hopefully if I ever need it , it will work as intended !
They are supposed to be the best legal ones to use

Frayz and Ian,
Firstly, ive been on the recieving end of a track fire at Spa and the 2.25l AFFF i had was nothing more than a token gesture .... but i fully believe it did enough to stop it properly getting hold before the martials could get there and empty another two martials extinguishers into it aswell, and as a result there was enough left to warrant reshelling it. With the rebuild ive gone for an underbonnet swirl pot so the plumbed in system went in on saturday and theres some passenger seat adjust lever mods needed to get the 2.25 handheld into the footwell.
Secondly, a mountain of AFFF into an engine bay causes ALOT of mess and is very corrosive! The thought of the plumbed in system going off at the wrong time is ..... well it wouldnt be pleasant cleaning it out.
Those dinky flamebeater things exist only to fill the euro legislation of every car carrying an extinguisher ..... might aswell use colourful language for all the good it will do!
My question is though, has anyone heard of an alternative to AFFF called monex .... or monnex ..... something like that! Apparently some circuits use it in theyre trackside extinguishers but its alot more expensive than AFFF so hasnt become as commonplace. When it hits the fire as a powder the heat causes it to foam up and release a gas, the change of state from powder to gas pulls alot of heat out and the foam created starves it of oxygen. From the stuff i heard though, for plumbed in systems i think it would be a viable alternative.
When i was trying to source motorsport monnex, the story i was told was that monnex is only available as a refill at the moment, so unlikely to have made its way into specialist markets, however any AFFF extinguisher could be refilled with it.

Anybody else come across this?

The problem with making a bracket is it fouls the seat aduster rail on the front of the newage cars seats. I am currently working on something and will let you know how i get on.
Interesting thread guys, I am still trying to decided what extinguisher to go with, for me the value is in stopping a silly little fire rather than trying to save the car if something went really wrong. And getting out!
I was considering Co2 but looks like I need to keep reading around the subject. Would be interested in a bracket at some point so will keep an eye on the thread.

A friend of mine made my mount for me last week. I'll get some pics up soon. It didn't budge at Saturday's Snetterton sprint session so it did the trick very well. He is willing to make more should the demand be reasonable.
