914World.com _ The Paddock _ On-Board Fire Systems

Posted by: iamchappy May 15 2008, 02:41 PM

I just purchased a SPA AFFF Multi-Flo Mechanical Fire System - 4.0 L Steel bottle.
manual pull cable unit - has 6 nozzles.

This is going into my street turbo car, i thought things over and felt it was cheap insurance if my car ever caught fire. It's kinda heavy at 15lbs and has 4 liter capacity
but i picked it up on sale at Pegasus for 295.00. On a street car i dont think the weight and size of the tank will matter much.

Post pictures if you have them on how and where you installed your tank and nozzles

I haven't done this yet. I'm planning on putting a system in the Spec Boxster that we're building now. I'll be watching this thread, hope you get some helpfull responses, more helpfull than mine at least.

I have a Firecharger AFFF system but my front trunk is such a disaster that I'm afraid to post a pic. It looks as bad as my kitchen after a big BBQ.

Where did you mount your nozzles....
I wont judge you on your front trunk, mines been there, done that....

I was figuring on mounting the bottle there.

I have a fuel cell on the floor of the trunk so the bottle is where the gas tank was. I have 3 nozzles- 1 just above the fuel cell on the F trunk firewall, 1 in the middle of the dash to put my balls out if they catch fire, and 1 in the middle of the F firewall in the engine compartment.
My car did catch fire once, those little 10BC Purple K fire extinguishers don't do shit to a fire any bigger than 2 matches.

I decide that i will mount the SPA fire bottle in the front trunk I might improve on the mounting bracket i was surprised that it's not that heavy duty. I ran the discharge line down the center tunnel with the SS fuel lines. I will splice in one nozzle under the fuel tank and aim it at the fuel line fittings. I decided not to put any in the cabin i have the hand held Halon mounted on my seat, and if i had too, I would rather discharge that in the interior than the foam.
I will focus the other nozzles in the engine bay with some that will spray the bottom of the engine on both sides, one to spray the fuel pump and fittings the fuel filter and accumulator, and the other nozzles will focus on the fuel distributor, WUR and injectors. I have 6 nozzles to spread out to aim and fire in those locations.
I will mount one cable release in the cabin.
The other cable release is suppose to be mounted on the outside of the car for track workers, I will mount it but not hook it up to the bottle unless i plan on tracking the car( i would hate for some joker to pull it ). It will be in an inconspicuous spot that is easily reached i can mark it's location with a decal if ever needed.

Can you post a picture of the nozzles? I'm curious how big they are.

You can see them in the plastic bag in the picture the anodized red fittings, I guess the nice thing about them is they are push on fittings so they dont need much room behind them and no tools required for installation. They have a collar on the end that when pushed in releases the tubing...

I think i would like 4AN better, we will see...

Well i have the system in, i ran out of cable clamps and i will have to wait till the engine is in to figure exactly where to aim the nozzles. I plan on making some light weight nozzle support brackets to finish it off.
I placed 3 nozzles on top and 2 on the bottom. I have one left that could go under the fuel tank at the fittings, but i may not use it.
I put some pressure on the shop to get the engine back together, i will now be a pest about it because i have seen this play out before, when the racing season starts the engine wont get done till October, they have already started racing the past two weekends. Once more he said it should be done in the next two weeks( he started telling me this in February).
My dash is full i am done with things to switch on and off. I have under the covered switches from left to right- LC-1 AF/R calibration button, tranny cooler pump, intercooler fans, boost retard, ignition kill, and fuel pump.

The pushon fittings and tubing worked smoothly and did make things very simple.

I hope i never have to use it, but glad it's there if i ever do

Nice install Chap.
I think I'll fly you out here to do mine !
I'm doing a similar install in a few weeks, POC racing started up again--taking most of my time
