flamethowers...hehehehe

so ive been coming up with ways to throw a large flame from my stack. reason being, im tired of dumbass kids around here. i got my truck egged and chased some kids down. im sure the 4 150W spotlights, loud stack and barking tires was enough to scare the hell out of them, but if i only had a LARGE flamethrower i probably could have made them cry. i want this truck to look like saitans child coming to eat somebodys face so i thought about using a propane setup. possible, but i would have to have a big propane tank under the bed......not really what i want. i have a 35lb./hour fuel injector. i am thinking about hooking a pump directly to the injector (walbro 255LPH that i have laying around) no return line, no pressure regulator. just straight pump to injector. there are a couple of problems with this. 1. its risky to blow off a fuel line. it would take a lot of work to make this safe 2. i have to find a way to fit this in my stack. not to mention having a small tank for gas. i doubt diesel would ignite with a spark lug. another issue i have is ignition. on a gas engine, you can ust take the -contact on the coil and run it to another coild (switched) for a spark signal. obviously this is harder on a diesel. i either need a switch that when in the on position, it turns on and off really fast (some type of capacitor maybe?) or use an ignition module and rig it up to a pulse from the engine (CPS maybe?) to trick it into thinking its a gas motor running then send a signal to the coil. any thoughts other than "not safe" or "illegal" because i onestly dont care lol. if anyone has anything that could help. please let me know and ill keep posting progress on the project.

BTW ive made successful flamethrowers on gas motors before. obviously diesel will be a lot harder.

With my luck, I'd burn the truck to the ground!!!!

That’s exactly what I was thinking, I bet those punks with the eggs would have a good laugh at me trying to put my flaming purple truck out.

Man this sounds so extremely dangerous...

I've only seen flames come out of high performance diesel trucks but that's after their pull and everything is "winding down". Like double overtime for instance....Although, I'm sure he didn't build his engine for flames

your spark doesnt have to spark multiple times. it can stay a steady arc and not hurt any thing. so a coil rigged to a 12 volt switchable power source ran to a spark plug in the stacks should work.

yeah that sounds bout right someone posted pics of an obs a while back w/ 10 ft tall stacks r sumthinand they shot flames!

do it the same as a gasser with a coil on a switched 12v now for the fun of gettin fuel to the stacks you could use a old eather set up like the old log trucks had a line and a can push the tip down fuel goes out the zost

i made the fuel system. i used my old walbro 255 pump and a 35# fuel injector. it will be hooked up so the injector opens and the pump kicks on at the same time. i tested it out and it works perfectly. i just need an ignition source. if you leave a constant 12v hooked up to a coil it doesnt spark untiul you shut the power off. you only get 1 spark. thats why i need a switch that pulses really fast. ive been thinking about it all night. i just need to make a trip to my local electronics shop and see what i can put together to make it happen. i need a capacitor to take in power and when it fully charges it needs to release the power, sending it to a relay. then recharge. im just not sure what it will require. ill do some more research. once i build this thing, i can start hooing it up in the truck. i wont stop until i see atleast 4 foot flames lol. with as much fuel that was shooting from the injector, i should be able to shoot a LARGE flame.

is there some way to make a remotely activated bbq lighter?
