my homemade exhaust flame thrower

the system wired like this uses the distributor points as a pulsing ground. which while the engine is rotating produces the repeated ground path to fire the coils several times. every car with a triggered ignition system is capable of doing this, and actully must to run. you are just transfering the (explosion) from inside the cylinders, and moving it to your tail pipes. you just have to remember to "let go of the button" before the engine rpm slows to the point of stalling.

i used to sell these kits in the 80's and 90's and have done it similar for years. even without the relay, using a 3 way toggle switch.

good post and a cheap way to get flames. thanks for posting.

Actually some fellas just get a distributer and wire it up and turn it with a starter motor in the trunk. It has no affect on your engine ignition this way.

You can even hook up a propane take with a solonoid to get those beeg ol' monster flames that every is really impressed with. I knew a fella that did that and went from 3" to 9 almost instantly.

Zman,
I like bobbers real well. But the wife knocked the devil out of the last one I brought home.

When are you fellas going to get it correct, a stripped down bagger is not called a bobber it is called a fat bob.

 

hell yeah, propane injected right into the pipes, and fireball igniters? (distributor looking thingy's) thats how my dad showed me.
he even went so far as adding a tank and valve, filled the tank with coleman oil, would drip burning oil on everything! hahaha
crazy shits.

 

Kinda what I have set up in my trunk......I used a wiper motor and just the points plate though. Works great when I use it (which is about once a year to see if it still works) and it sounds like a gas stove trying to light!

Regarding the propane, a buddy of mine back home did that and melted the paint off his trunk in a hurry! Pretty good show though! We had fun building these gadgets just to see if they worked.

Bobbers.......ugh......I'm on Jockey Journal alot trying to keep my old Triumph on the road and that word over there is like "r@t r0d" here. Only difference is REAL bobbers are cool and very rare!

Porknbeaner, you seem like a pretty knowledgeable guy.......what is your take on how bad it is for the engine?

Dogpatch, explained that way it makes much more sense now. Couldn't zoom in on the schematic on my phone enough to really check it out.

Can anyone remind me of the correlation between the flame color/shape and distance from the the end of the tail pipe that you mount the spark plug?

 

Wow, people are still doing that huh?

 

Flamethrowers would be great for people who like to tailgate you going down the road. I think it would encourage them to give a little more space.

I know that it will take a lot out if you are running it down the road while you do it. I don't know that it actually hurts your engine but from what I have been told and logoic makes me think that is it true it will make you run a little lean while you are flaming because it causes an enhanced scavenging effect.

I think that everyone makes it all too complicated, if you could land some model T coils you can bypass the distributer all together. When I was a kid (this is kids stuff after all) I wired 4 of them to a double throw switch, with a neutral in the middle, they would dwell on their own when not fireing and you just switched the toggle back and forth. On 12V a model T coil makes about 80,000 volts, at least that's what an old timer told me, I never checked. I was runnin a tri power on the 312 I had in my '55 wagon, and side dumps. Rev it at the light, pull the choke and hit it.

The trill wore off real quick and I wired the coils to my body for a theft deterent.

I don't hang on the jokey journal, like the HAMB it probably attracts a lot of wannabes. I was a tramp when I was younger and never really liked the wannabes and hang arounds. Not that it makes me any better then them just different.

i've noticed. the closer you mount the plug to the end of the pipe, the shorter and fatter the flames

about 8 inches to a foot in on the plug, gets mine to a blue flame about 15 to 2foot long. working a choke too.

it does wash out rings with constant use. so i'd recommend using for tailgaters or parades ect. hahaha

A hand full of old screws works real well for tail gaters, it isn't as high tech. I discovered that a torn up paper napkin works real well also, it freaks them out when you toss it out the window, or over your shoulder.
Both will piss them off usually, then a snub nosed 38 works real well, I used one of them on a Peterbuilt once after the napkin didn't work.

But that is pure road war and I have to hand out this disclaimer, do not try this at home kids.

 

I'll ask again.
Why cant i just wire the coil to the battery with a switch to light the spark plug instead of hookin it up to the dizzy?

As for tailgaters, for those with adjustable suspension hittin the rear end switch making it go up n down a couple times seems to work efficently every time, from a foot to 50 in about 2 seconds.

 

Because it will only spark once. You need something to cause repeated spark, such as wiring to the distributor or an electric motor with a set of points or electronic box or whatever.....

 

So basically i would have to keep clicking the button or hitin the switch to have spark?

 

when i made my own flame thrower i used a four cyl dist hooked up to a heater blower motor and took the spray nozzle out of a sure shot can installed a electric fuel pump(i was running lake pipes) put the nozzle in the front of the pipe first (not a good idea but big flame when you unload the pipe)3/4 way down the pipe worked best nice 3 ft flame at idle and a 8 ft
the good thing about doing it this way was when the pipe would get going it would stay on on it own couse the flow of fuel and air mixed at the end of the pipe only if it whent out i would need to hit the spark again

 

I have an easier set up that involves a HEI distributor and wire and a fan motor, the rest you should be able to figure out...thats how the big boys roll in the contests, by the way you can use this set up and use the choke

 

what (Night) said

 

Some pics

 

what a dumbass thing to do to a car.

 

I think I would be concerned when it is switched back from flames to normal running, sparks from the now firing engine igniting the overly rich mixture left on the exhaust pipe and setting of a muffler blowing explosion.

 

Not the right forum for this.

 

Cool! So that is how it works. Ya know, I have seen them at Lead East and teh other shows through the years; somehow, I thought they were a lot easier than what is explained. All in all, that's a lot of wiring.

 

If there was ever a thread that should be deleted this is it.

Unsafe juvenile garbage.

 

To each their own, Hoss

 

haters gonna hate

 

Close it down. Sucks some think this crap is hotrodding. WTF?

 

I like it.
