Flame throwin' - who has them??? TECH REQUEST

hey bro. if you got the money, get a kit. if not you cna do it my way. i think i spent a total of like $20. get 2 spark plugs and nuts and weld them to you pipes about 6 in. before the tip. then go and get 2 coils that work from the junk yard (or grab a bunch at night and hope atlest 2 of them work). then heres how to hook them up.

1.mount the coils close the the plugs. make sure they arent tips upside down.
2.then run power to them from some sort of power. if you run them directly off the battery, that is your best bet. put a toggle switch between the coils and the power sourse.
3. run your negatives on you 2 coils to your negative on your primary coil.

that should be it. the sparks should be an off/on to where it looks like its on constant. if you need more fuel use a manual choke. if you dont have one get one from napa for around $8. that should be all. have fun lighting up the streets.

I had them on my old Volvo. I used the autoloc kit and then injected fuel in the tailpipes.

 

I have a friend that is big into them. He uses a EFI pump, on a seperate fuel cell, run to furnace nozzles in the exhaust. For spark a high output coil and a distributor with an electric motor to turn it, Salamander spark plugs in the tailpipes. The bigger diameter tailpipe, the better the flames.

 

HEy I am new to the board,

Been reading about flamethrowers and it would seem that fuel injection with a seperate ignition source is the best and least motor damaging way to go.

Do you need a 95psi pump with a car type fuel injection nozzle or just run a low psi electric pump with a winshield washer nozzle?

Got a slant six with side exhaust I want to do this to.

 

A low pressure pump with a hammered over brake line work very well. You want to almost squash the brake line shut so you get a nice fan of fuel, not a big stream. Also, if you wrap teh brake line around the pipe a few times before it enters the pipe, it'll preheat the gas and help it vaporize. Personally, I prefer propane injection. No luquid fuel to pool or drip and cause a mess. For a small system, a nitrous solinoud works ok, but generally they don't really flow that much. If you want a whole lot of propane flow, a 12V fuel solinoid off an LP forklift works very well.

 

And just run a Home Depot propane tank, like for a BBQ pit?

I can get the forklift part pretty easy. My dad worked for Hyster.
Do you need a regulator?

 

I stole this one from somewhere, I'm sorry if it was some of you hambers...

 

got a kit that sucks. built my own and its better but not great. it was very hard to do but its gas injected with realys, nos injectors, coils, 4 plugs, etc, etc. man was it a pain in the ass...

 

i have flamethrowers on my 51 merc pick up for 5 years now. no problems with them.4 plugs 2 on kd boxes. an 2 plugs hooked up to coils under truck that cut out ign and pump the peddle like hell.also have nozzels in pipe. plus a nozzel on outside of pipe. can shoot 20 feet. i use theam all the time an never killed a motor yet

 

going to bring this thread back. In the pic of the Volvo it looks as if it would light the ass of the car on fire. What are the chances of burning the car or truck?

 

The pic ofmy Volvo is a little decieving. Its not really that close to the car. Its probably at least 18 inches. My tailpipes stuck out the back of the car a good 6 inches.

But, if not done right, or if you backfire, you can definatly hurt your car.

 

Can't wait for next week's tech on installing mudflaps ...

Ask Tuck about burning down cars. It wasn't his, but it's a great story none the less

 

this is my home made flame thrower.
It is just the first try.It only gives 20 fT flames.
We are aiming for 100 + FT

 

Shit. After seeing that im not sure if i want it to go that far. Im all about burning shit up but those flames seem that its too easy to burn a pedestrian or another car. Cause i do want to be able to use them on the street

 

Hows this for a flamethrower?

 

Shoeboxhero-
Bet that guy won't eat beans and boiled cabbage with jalapeno sauce again! Pootin' won't ever be the same!

 

Havent rigged up a kit yet but I have a 2.5lb nitous bottle I plan on filling it 1/3 with kerosene and 120psi of air pressure. Firing it out of a 50hp fogger nozzle and lighting it up with a surface gap spark plug. Air, fuel, spark. Have you seen the oil wells on fire during Desert Storm?

 

I hate those things!

 

i have them, they come in handy, one of my mates killed two motors with flamethrowers, but i used mine daily for 5 years and when i pulled the motor down to rebuild it for a supercharger all the internals still looked new, i used to make kits but then the prices went up with some of the parts suppliers and it didnt seem worthwhile making them anymore but if anyone has a kit they bought from me and anything goes wrong, ive kept a stash of parts and can fix them for nothing.

 

People usually kill motors when the use the kits that require motor revving and the continuously rev about 2 grand or 2500. I know that the last motor I had looked like I was baking a chocolate cake inside of it. I don't do it anymore and I think it gets out of hand when the propane guys do it but whatever floats your boat.

 

yeah its easy to get carried away at a show with a crowd cheering you on, thts were my mate blew up one motor when we were trying to out do each other, i never used my choke becuase the rpm died to quick, i used to go over 5000rpm with a holden 6, my mate had a 429 ford motor, you have to watch your engine temp and listen out for thin oil, its like in a burn out comp, you get a short amount of time to make big tyre smoke and throw the car around, sometimes the oil cooks in 40 seconds and the engine gets noisy, also you need to change the oil frequently, but i was expecting to see some kind of severe wear in my bearings or bores when i pulled my motor down, after it being together for nearly 10 years drag racing, burn out comps and flamethrowers, but when i pulled it apart it only just looked run in, i was disapointed that i was taking all good parts out of the motor

 

I like fire......................fire.................fire!!!!!!

 

Doing it all wrong

http://store.summitracing.com/egnse...alse&Ntk=KeywordSearch&DDS=1&N=700+400122+115

and pump a ASS load of gas in the exhaust.. don't be scared

 

Tell us how that works, will the spark be hot enough to light off kerosene?

 

I member taking this diagram of the HAMB last year....

This is generally how the kits work.
A more motor-friendly (and fun) way to go is:
-Get an EFI fuel pump that flows a ton and run a line from your fuel tank to it
-Run a line off it, split the line w/ a Y-fitting, and then run a line to each exhaust pipe.
-At the ends of each line you put a one way flow fitting (to keep burning fuel from heading up the line)
-Next another small piece of line and then a pinched piece of brake line as a nozzle, clamped in.
-Now you wire the pump to a switch in your ride.

**The Nitrous nozzles sound like a good idea but they suck. They make little, puffy flames, due to their atomizing fuel rather than spraying it**
I'll let someone else explain the wiring, as I'm shit with it. Basically, it's the same set-up as the kits, minus the fact that you don't need to bathe your cylinders and you don't need to cut ignition to the motor to light up.
And here's the key bit of info. that most people fuck up on: Use hot rated Diesel glow plugs rather than spark plugs. Spark plugs don't much like having fuel sprayed on them.

Because you are actually spraying fuel rather than fogging it you can do a neat little trick.
1. Find a nice road w/ a bunch of dirty bitches in tube-tops hanging out.
2. Hit the switch to your fuel supply and slowly roll forward about 20 yards w/ out lighting.
3. Light her up.

Result: Two big ol' strips of flames running 20 yards down the road and dirty bitches in tube-tops thinkin' you're one cool cat.

**I recommend not doing this w/ people behind you, but hey, it's you're choice**<o></o>

step 1. Get 2 spare coils and some plug wires
2. Mount the spark plugs into the tailpipes.
3. run a wire from the battery to the new coils in parallel
4. run a wire threw a switch between the condenser wire(engine coil "-"), and the new coils
5. Rev up the engine and hit the switch, and pump the gas like mad.
6. enjoy

Footnotes:
this system essentially robs the spark from the motor. as soon as you hit the switch, the motor will start to die down. Make sure that you shut the switch off before the motor stops spinning completly, or you could get flames traveling back up the exhaust. You won't blow anything up, but it could travel all the way to the carb and start a fire.

This is hard on the motor because you are running so much raw gas threw it. it washes the oil off of the cylinder walls, as well as diluting the oil in the crankcase. Change your oil often, evert 500 miles or so.

Flame throwers and NOT legal anywhere on the road, and in alot of places it's not even legal to have plugs in your tailpipes. However as long as your not using them on the road, most cops don't really care. car shows and your driveway are private property, and thats why you can use them there worry free.

Another way to do it is to hook a distributer and a coil up to a 12V fan motor. then just run wires and plugs to the pipes. the motor spins the distributer just like the engine does, so basically, you have a complete ignition system in a box in your trunk. Also handy for spare ignition parts on the road.

And I still need a copy of the So-Cheap wiring diagram site<o></o>

Why not a Ford Model T coil? Just hook it up to 12 volts thru an ignition resistor. The points vibrate and that is just like points in a car. High voltage output; run directly to your plugs. You might need two, one for each plug. But this way no need for distributors or motors to drive them, and the Ford coil fits into a small wooden box. Check out Snyders Model T parts.

Has anyone ever installed flamethrowers on a car with Lake pipes?

 

No, but mine shoot out the sides. Lots of fun when trying to merge on the highway. Using the plans from tnga.org. works well. I have some leftover fuel injectors from a Seabring engine swap I have considered using, not shure of what it will do.

 

I've got Model T coils on mine, and they used to work pretty well. Haven't really messed with them in a while.
