My friends and I made a short video of my truck showing my home made flame throwers and also you get to hear my truck. Its not as ricey sounding when your driving it. It only has that ricey sound when you rack on it or when you floor it between gears for the flames.

That's pretty good!

 

did you use the old spark plug trick or something else?? care to share??

 

That is great!

 

well its really simple. I just welded nuts into the exhaust that fit some cheap spark plugs and hooked up a coil for each tail pipe and wired it up. This worked but the flames would shoot out and then die. I put a manual choke kit on it so I can choke it out when i rev it up to produce the big flames that stay there. If you lisen you can hear me push the choke back in and also when i over did it and almost killed it. I am going to be cutting the nuts off the tail pipe soon to put in no foulers that i will cut down so that I can use a hotter spark plug. The nuts i put on the first time only work with lawn mower plugs. I want some plat 4 plugs! If you want more details on the wiring just ask.

 

what did you use for a coil?? couldn't you just run it straight off your battery with a switch??

 

no you can't in order for a coil to spark it takes a on off signal. The on off signal has to be very sharp. The way a coil works is that a coil of wires induces a current inside of it on a seperat coil that has many many more windings. This steps the voltage up but lessens the amps. When the coil losses voltage this causes a voltage spike in the secound coil witch is conected to the distributer on your motor. For my exhaust its just one spark plug. To get this signal I spliced into the negitive wire coming off of my engine coil. This wire is also your tackometer signal wire. I ran the wire to a relay. I operate the relay in the cab with a push pull switch. When i turn the relay on it sends the power down the wire to my first coil on the driver side then the negitive or ground wire from that one goes to the positive on the other coil and then the ground wire for that coil gets grounded. You just use short spark plug wires to go from your coil to your spark plug. This sounds very complicated but its not.

 

for coils I used coils from my old junked out ford trucks. They are like 10 bucks from an auto parts store. Any coil will work if it has two termanials and the plug for a spark plug. This coil looks like a long tube with a cap on the end and some wires. they are found on old dodge, ford, some antech tractors, and some bigger lawn mowers.

 

cool, i understand now...thanks!!
