Auto Exhaust Flame Thrower

For this one, all you need is a car, a sparkplug, ignition wire and a switch. Install the spark plug into the last four or five inches of the tailpipeby drilling a hole that the plug can screw into easily. Attach the wire (this is regular insulated wire) to one side of the switch and to the spark plug. The other side of the switch is attached to the positive terminal on the battery. With the car running, simply hit the switch and watch the flames fly!!! Again be careful that no one is behind you! I have seen some of these flames go 20 feet!!!

 

Bet that would work pretty damn well on a 2-stroke, especially dual exhausts. The CDI is right between the silencers too. Only problem would be getting the spark plug in there right. Unless you got rockets or cpi's, the stingers are probably too small. Don't know how the silencer would handle it either. Someone better try this before this post makes it to page 2 on gen discs. :)

i'm pretty sure you either have to be running rich, or briefly cut spark to the engine so it forces raw gas through for it to have something to ignight, i've also wondered how these work with the lack of oxygen after the fules been comusted.

when i saw a car do it it sounded like he reved it up then the motorsounded like it stoped and right befor the motor stoped reving and turned on and a 5-foot flame shot :lol:

2-strokes let some of the mixture out the exhaust before closing up the port, i guess that will ignite, then when it hits the air it will blow. It could be done to a banshee, but i'm not gonna hack up my fattys for a flame that might work.

we putt one of these on a 55 buick. If you have a manual choke you can just choke and rev and get off the gas quick and get a flame but it wont be very big one.the ones you see with the big flames have propane running into the last part of the exhaust.

i heard that doesnt work on fuel injected engines. is that true? i didnt hear why.

its probably because of the 02 sensors, keeps them runing just right. i know on my old 85 ford (carbed, straight pipes) it can shoot flames out. i think the regular 12v battery can ignite the sparkplug....???

atcually its a very low percent( in think like 33%) that actually will combust in the chamber the rest evaporates through heat in the exhaust so you can still ignite the fuel with a spark when it comes out , but you have to rev the engine and cant have a covertor and shit like that on it

saw them install this on an episode of TRUCKS, just hook it up and make sure you dont have a catayitic converter....will not work with on of those

in that episode he used some thing to kill the spark so just raw fuel went threw the engine and out the exhaust.
