Flames from the Exhaust

I saw an Auto show on TV a few weeks back that showed you how to place a spark plug near the end of your tail pipe with a coil connected to it. This would produce flames. I didn't see how he did the wiring.
Does anyone know where or how this is done. And yes I know it's illegal in some states but it would be cool to have. It sure would get the tailgaters off your bumper in traffic. But can you imagine how cool that looks at night.
If you can help with this that's get, but not really looking for a long leature on why I shouldn't do it.
Thanks,
Kevin

Seems to me you would also need to provide something to ignite. Exhaust gas isn't too flammable. You aren't going to light it with a spark plug. If you can, your engine isn't running too well!

Typically it uses some sort of ignitor in the tail pipe, a coil and a kill switch for your ignition. You rev the piss out of your engine hit the kill switch which shuts your engine off (so you have unburnt fuel entering the exhaust) and the ignitor lights the fuel. It won't work on a car equipped with a catalytic converter and probably won't work on a car with EFI.

You can actually purchase a flame kit if you want rather than trying to rig up a potentially harmful (well....more harmful) ignition device.
Let's face it ... atomizing a propellant that close to your vehicle ain't doing your paint job or other parts any favors, much less anyone or anything behind you. (However cool it might be. <grin>)

Having 20 foot flames shooting out the rear of your car is a "must have?"

Not for me but someone had asked about them and I thought the text from the site was pretty funny. I saw a guy put something like this on his Harley and I gotta admit it did look pretty cool at night.

side of an auxilliary ignition coil. The secondary side of course feeds sparkers in the exhaust tips. Tap the button and immediately release. The spark occurs when primary current is interrupted, so holding the button won't do anything but overheat the primaries, building resistance and lowering current to the point that the secondary's induced voltage won't be sufficient enough to fire the plug.
Works best on a carb'd car as fuelies run "too clean" and there isn't any raw HC in the exhaust stream (particularly with a working cat, as posted already.) A manual choke is desired as the carb can be calibrated properly for driving, and yanking the choke shut will pull in enough fuel to carry on through the exhaust (assuming the mill doesn't stall from loading up.) I prefer pull-over enrichment equipped Q-Jets, identified by two small holes in the air horn choke tower just below the choke plate, back side. (some carbs have them above the plate, I believe.)
Killing the mill's ignition while revved up, as posted already, would probably work, but if yer already melting yer bumper, why mess up the motor too? Besides, then you can't modulate flame intensity with the throttle.
I once had the brilliant idea to use a nitrous solenoid to control a propane bottle. It's probably a good idea that I never tried it, as the result would most likely have been, well, "spectacular and all-consuming."
Have fun watching your cat melt clean off the car. BTW, my last motor suffered a thrust bearing failure and trashed the crank. Come to think of it, the oil smelled more like gas than anything else...

From what I know about these flamethrowers, is basically what everyone else has said (rev the engine, cut the ignition to allow raw fuel into the exhaust and hit the button for the plugs in the tailpipes). However I remember seeing a homemade setup where the guy put some fuel injectors directly in the exhaust pipe and plumbed a secondary fuel line to these injectors. Therefore whenever he wanted the flames, all he had to do was hit a button to dump the fuel directly into the exhaust for as long as he wanted the flames - no monkeying around with the ignition necessary.

In my youth I had an old Chevy that I did it to. I ran a wire off of one of the sparkplugs, and mounted a sparkplug in the tailpipe. The car had a manual choke so I would just pull the choke for a second or two to flood the exhaust with fuel, and the flames would fly! The exhaust exited before the rear wheel, pointed straight out the sides. I would pull up beside a friend on the four lane and let it rip! The reaction from the other driver was priceless when they had no idea what was coming! Greg
