Flame throwers

[PullinRam]

In july i will be in a burnout contest at a local truck show. I really want to please the crowd somehow so the thought of adding a flame thrower kit to my stacks would be neat. Is there a way to do this without having to tap a spark plug into the top of my stack? I want it to be hidden basically and i'm also curious what fuel it should run off of. If anyone has any ideas or info that would be great. Thanks in advance.

I have been looking for the exact same thing. Please let me know if you find anything. Thanks.

You could use one of the electric igniters (piezo). Here is one site. Natural gas heaters also use an electric type of igniter. Find the type where you just throw a switch or push a button and it sends a spark as long as the connection is made.

I think propane would work but I'll defer to others.

very good thread, i dont have stacks but i could see myself doing this!! maybe i could charge to use it as a weed burner! i agree, propane and an ignitor sounds feasable, but then again i have lost my eyebrows a time or two!! :-laf

I have seen this done on an exhibition 4 wheeler, I am sure it was a spark plug and propane fed.

A flame thrower would be really wild... I would love one that could maintain a flame for a minute or so..... sure would surprise the ricers...

Think a guy could get away with it at a pull?

Does anybody actually have any answers to his question? I am interested too and would like some tested ideas.

I've got plans in my head, but not sure how well it'd work...



weed burner tips fed w/ propane... my only concerns are the igniters and how well they'll burn being fed diesel exhaust vs. fresh air...



I could figure out the ignition, but I'd be ticked if they didn't light/burn right due to lack of air... don't want to have to feed oxygen too!

PS, it'd be VERY easy to plumb with a box crossover system...



maybe one of these days I'll try it.

I've never done it on a diesel, but have on a gas motor. basically heres what we did:

we welded a fitting in the exhaust about 8" from the exhaust tip, and put in a spark plug. we hooked up a coil and plug wire to it, and ran a switch to feed power to the coil. It was also hooked to the coil on the car, and when you threw the switch, it cut spark from the engine and sent it to the exhaust. the car was carb'd and all you did was get going, flip the switch, and start pumping the gas. It would send the raw fuel out the exhaust, and walla, fire!

Perhaps you could use an orfice and just plumb it into your stacks, run propane to it, and ignite it. I really dont see it burning very cleanly, though. Mixed with diesel fumes, it will probably be sparatic.

Erik Staceys truck shoots a flame out the stack, but probably not by choice! :-laf

The East coast drag truck "Showtime" has a setup like this, only on their rig, they have a bottom exhaust for the engine, and the stacks are strictly for shooting dual propane flames 20 feet into the air (at least that's how I remember the setup, maybe its different?). I can't seem to find their wedsite, tho. The truck is a converted 6 wheeler Mack daycab, painted yellow and white, with a Cummins 855 and an Alison automatic in it. It's one awesome machine. Maybe someone else knows what I'm talking about and has the website link??

I did see an episode of Monster Garage where Jesse used a fuel injector mounted upstream of a sparkplug mounted out near the tailpipe. I think it had its own seperate little fuel pump wired to a switch. It seemed to work good and looked really cool too!

Just how easy we talkin? That's how mine are setup (with the a crossbox). Im really serious about doing this but very confused haha. The info so far has helped me a bit. Thanks!

i did, i got a 94 CTD heavily modified, last season i was throwing a 6 " flame out either stack at a local pull, i had a fuel timing problem, it looked so sweet!

There is a guy on the ford forum that has a propane setup for his stacks. He says it only works at idle because the airflow will blow out the flame with throttle. He discussed it a while back.

Was that on purpose?

I saw plans where they used one of the Ford Duraspark ignition boxes and an oscillator circuit to fool it into thinking it saw a distributor. Flip the switch and flame away. The thread was on fordtrucks.com in the 48-60 forum.
