Didn't really know where to post this question- I guess here is as good as any place. I was dinking around the internet today and I stumbled onto a website that makes a product called Flamethrower exhaust. It's one of those things that you put sparkplugs into the exhaust tips. When you hit a switch, the plug sparks and ignites the unburned fuel, shooting flames out of your tailpipes (they say 20+ feet, and have a video showing it too). I'm sure you're all familiar with the idea.

Anyway, I think this might be kinda neat to do. How many cars do you see that can have a fireball come out of the tailpipe on purpose? So I did some more looking and some say that you can just put the plug in and hook it up to a switch, then directly to your battery. Would this work? Is 12+ volts enough to arc across a plug gap? The Flamethrower kit is just some sort of box. You have to buy two coils and plug wires for it. I can't figure out what the box does. Maybe I don't know enough about how to hook up a coil to produce the 20,000+ volts that a spark plug sees. Anyone done this? Any suggestions? Any opinions on if it's a good idea or not?

Sounds like an easy way to get arrested... If you know a sly bail bondsman, then go for it

granted its cool BUT you have to be careful that backpressure wont pull the flames back into your engine - ouch!
plus, especially with our mustangs, id be worried about the tank somehow catching haha (i knwo its not funny but i laugh anyways )

its really not worth the risks to me, but it still is cool

This is a very old trick and requires more than a plug hooked to a battery to work well. With an n2o fogger nozzle in each pipe and a good spark box a flame of 65+ feet (last I heard) has been recorded, however if you just use the rev, choke and spark method the flame only goes 5 feet or so. As mentioned by Thumper the whole practice is frowned on by the constabulary, also be sure the switch is not easy to bump by accident people can get way out there if you burn the paint on the front of their car .

Something that is quite popular here is ... well, I don't know how it works, but when you take off, an audio track of wildly screaming tires plays from somewhere out the back of your car. Should go well with the flame thrower
Personally, I like flames coming out of those drag cars with eight separate exhaust pipes stacked at the back and pointing at the heavens!
Is a Stang the right car for this though???

I did this EXACT modification to my mustang back in high school. The box "Flamethrowers" sells is nothing more than a switch! All you have to do is wire it up like they say in the FAQ (installation instructions) and it works. All you are doing is grounding out the engine coil and sending the juice to the coil in the trunk. When this happens, the spark to the engine goes out, and the coil in the trunk energizes the spark plugs in the tailpipes. When the button is pushed, you just pump the throttle to send plenty of raw gas through the exhaust system... which gets ignited as it leaves the tailpipes. (Double Pumpers work GREAT!) Blue flames will shoot 2-3 feet out the back of the tailpipes, making a popping noise. As a high school teenager, I thougt it was the coolest thing I had ever done to the car! Of course, this modification won't work with fuel injection or catalytic converters. When you let off the button, the engine's ingition re-ignites and returns to normal.

The Flamethrower kit is just using a relay to switch the power between the coil at the engine and the coil in the trunk. When the button is pushed, the power to the engine coil is switched off, and the power to the coil in the trunk is switched on.

I can't remember my EXACT setup from the high school days (I'm 34) but when the button was pushed, the coil to the engine turned off and the coil in the trunk turned on. The result (when the gas is pumped fast) was big noisy flames. It was really cheap and easy.... And FUN!

You do it with the engine running. It works best with the car in motion using a standard transmission that will keep the engine as you pump the gas with the button pushed. If you try and make flames sitting still, you have to rev the engine up to around 3-4k rpm, push the button to make fire, then let off the button (to restore spark to the engine) before it stalls.

That same button on my car now operates the nitrous purge. I no longer have tailpipes, so flames might cause problems.

A buddy of mine installed a set of fuel injectors in his tailpipes to 'enhance' the effect. His truck shoots MAJOR flames! I watched it shoot out so much gas, the parking lot caught on fire! (temporarily, until the extra gas burnt out) His setup is a tad dangerous for me....

Good Luck!

Yeah, me too. I was going to try that but I figured that it would be a wee bit expensive and I might end up burning my fenders, front tires, suspension, etc.

You might want to complement the flames with the installation of a genuine train whistle. Might as well announce yourself. If the flames don't get it, the whistle will! The guy here that has them on a 51 Blac Ford cpe shuts the motor down when the flames come on and then it comes back on. Appropriately, the car has classic flames on the front!

Flamethrowers were very big in the fifties, along with fender skirts and gangster whitewalls. I still see them at a car show I go to every year.

Why people think they're cool is beyond me...

You know I was just having a bit of fun, right? I'm not fluent in American English, but I know that sometimes "Have a nice day" means the opposite of what it says Actually, my day was quite exciting. My dog disappeared for two hours, and eventually someone came round to tell me she was down the street, locked in one of those perpetual embraces with a fella. A sharp whack on the fella's behind fixed it, thank the Lord!!!
