I know a lot about this topic, And i can tell you that the only way your going to get this to work is with a kit for about 100$. The Plug in the pipe wire to switch to battery is not going to work at all! 12 volts is not enough to jump a gap, there is no way. And to do the flamethrower on a EFI is pretty much impossible unless you put gas down ur pipe and throw a match in there. Why dont u get it over with a just blow up your truck.

 

Okay, I am buying this kit. Where do I get it?

 

In a lot of the hot rod magazines there in the back. just go to google and type in "flame thrower kit" you'll find some

 

cool thanks!

 

u can put flames on a fuel injection engine just run a wire from ur distributer cap to ur plug it only shoot about 6 inches though

 

hey that wont work. u need more than just a coil hooked up to a batery all the batery does is juice up the coil.if u take a wire and hook it to ur tack on ur distributer thats send a signal to make ur plugs spark.(and the will spark alot).take a nut weld into ur pipe and srew some plugs into them r45ts is a pretty good plug wire ur + batery post to the + side of the coil and tack to the - and put a switch on the baterry wire and a fuse link on the tack.then switch the toggle on hold pedal to floor switch key off then on still holding it to the floor u get about a 5 foot flame u need to let the rpms build up before turning it off though.all this works anfd doesnt cost but about 30 bucks.

 

with an EFI i dont think it can be done but i used to run an old 68 with a 460 in it and rigged it up to shoot flames. ferget these ##### *** kits they make what u need to do is to start off put straight pipe dual exhaust on it and run a carb.u get alot of raw gas comin thru your pipes then.then u cut holes about a foot, foot and a half away from the ends of the pipes.u bolt spark plugs into em and run them to a extra battery.then run that battery up to a toggle switch in the cab.flip the switch and git on that sumbitch

[updated:LAST EDITED ON 02-Jan-03 AT 11:10 PM (EST)]What you need is a seperate coil wired to a horn relay to cause multiple sparks, the relay works like a set of points where it sends pulses from your battery and causes the coil to spark consitantly. Just wire a 12v wire from your battery to a relay and then a wire from the relay to the coil. Then wire it to your sparkplug welded to the exhaust pipe. And also make sure your exhaust is grounded so it will spark.

Oh and another thing turning your key off and letting your engine backfire is a cheap way to get flames and a bang, but when you do that it slams open your valves and eventually they snap, sear, and cost a lot of time and trouble for a cheap thrill. Either do it right or don't do it at all.

I've never tried a fuel inj setup, but here's a basic setup guideline for carb, flame throwers sould be easy to hook up, and for under 20$. It mite work on a fuel inj or a diesel, I don't know.You need a coil, spark plug and wire for each talipipe. You also need a double trow switch and about 50ft of wire. The hardest part is putting the plugs in the pipes. Go to your hardware store and find a large nut that fits on your plugs and weld them about 6 in. from the end of the tailpipe. Now hook up and mount the coils and hook up your spark plug wires, somewhere in the trunk works. Now for the wiring. Find the negitive wire to your engine coil, disconnect it and run it to the switch which should be mounted near the dash. Now when you wire the switch, you need to wire it so when the switch is in one position, it only grounds the flame coils, and the other position it only grounds the engine coil, NOT both at the same time. There's not enough fuel left over to make any sort of flame, I've tried. Wire the flame coils by hooking the negitive of each coil to the switch, and run the positive to the positive on the engine coil. Then wire the ground for the engine coil to the other side of the switch. Now, when you think you've got the wiring done, you get to drive around shooting flames untill you get pulled over. Here's the idea. You rev up the engine, but don't redline it. when you trow the switch, the ground from the distribitor is redirected to the back coils, while the engine just pumps gas though the exhaust and the plugs spark and create a flame. First i get the engine warm, then what i do is rev it up, then trow the switch and pump the gas really fast, when the enggine revs drop alot switch the engine coil back. But don't let the engine rpm's drop to low, or it will backfire and possibly blow up your muffler (It hasn't happened to me yet, but you never know). You can also close the choke if you want, but I've found it works both ways. I get flames about 18-30 inchs long and they look like afterburners from a jet. I'm no expert on the dangers of flame trower, but try at your own risks.

 

I just saw a special on the flamethrowers on TrucksTV today the place they got their kit from was by the name of Auto-loc at 503-693-6608. I have to say it looked pretty neat. But I'd rather leave the flames for the ricers I'll stick with no show and all go!

I know this is a week late, but I must've missed this.

If anyone can take a wire from the battery to a switch to a coil and make a continuous spark, I wanna see it. I tried it and it doesn't work. In fact I've tried it all just to see what did and didn't work.

The key to making a "spark plug tester" is pulsing high voltage to a plug. You can accomplish this with a momentary switch, a normally-open relay, a condensor, a coil, and the plug & wire.

You could also build an electronic pulsing device with a 555 timer circuit and some misc. parts from radio shack.

If you wire the normally open relay correctly, when you apply power to it, the closed side will open and cut off it's own power. That causes it to close again and start all over. It will actually buzz as it opens and closes rapidly.

Because of the nature of electricity, this cycle happens too fast to let the current flow enough to charge the coil. That's where the condensor comes in. The purpose of the condensor is to instantly charge and discharge ALL of the power.

By sending power to the relay/condensor and out to the coil, you'll be able to charge and discharge it enough to generate the 40,000 to 100,000 volts it takes to get theplug to spark.

I have schematics, instructions, and photos of my working model on my website fi you want to know more.

Also, check out howstuffworks.com to find out everything you need to know about spark plugs, coils, relays, and condensors.

you need this chip that connects to your iginition and that cuts off the spark pumping unburnt fuel throught the system then you buy a cheap coil abd mount it near the exaust then you connect the sparkplug to the coil

 

Yeah i would also like to know how to do this! i used a plug and wired it to my distributor but i dont get flame plug sparks but it doesnt get flame how do i get enouph fumes from EFI????

 

boys boys boys. I was at the local car show here in New Brunswick Canada, and there was a flamthrower truck there. He had dual exhaust and in the tips he had a threaded in sparkplug. At the end of the tips he had an injector. We think he was using butane and as he hit the button the flame ball was at least 15 feet high. It was quiet a show. It also made a really cool werrel sound because the flames would be going inside and out of the tips. Really good setup. He was lovin' it, and the crowd was too.

Anyways, I want a flamethrower, so I can toast the ricers!!!!! Ha ha ha.
