Haven't done a flame thrower since high school days. We used a Model T coil hook up to a switch. You need soomething to give the plug the high engery spark. I would suggest you try one of the "custom sites" they now selll this in a kit form. Maybe the "Night Prowlers" out of Lamar, MO. for instance.

 

site for kits ,www.hotrodsofnorco.com might help

 

i saw one of these on trucks. THey put a spark plug into the exhuast and mounted a coil nearby. They they hooked up this control box to the ingnition that will turn off the spark in the engine so raw fuel will come out of the exhaust, while at the same time turning on the spark plug in the tial pipe....i can't remember the website though

 

yeah the web site is www.how_to_ruin_your_motor.com
(its not a real link)
If you really want to make them, it is best to have a seperate source of fuel, I know some guys that use gasoline, kerosene and other stuff, but the best is propane, but its also the most dangerous.
If you just hook it up so that the switch kills the motor and lights the tail pipes, it will push tons of raw gas through your motor and "wash out" your rings. I have a freind that ruined his caddy like that. He had to use 16 quarts of oil to get him home cause the rings were so bad.

If you want to make it a little safer take a small fisher regulator and take out the spring. This way the system will only get fuel when the motor is running. You also need to modify the injector so its at an angle. As the exhaust passes by it creates a vacuum. If the engine dies the gas stops flowing. (thats the theory anyway)

 

Haven't done a flame thrower since high school days.

When you hooked the plugs and switch up, did you need to do anything to your stock spark system to cut it off temporarily to get the motor to just run on momentum?

I guess my question is, is it really necessary to cut off the engine spark?

I have a 351W with a Holley 600 4bl on top. Can I just run it a little bit rich whenever I want flames and ignite whatever unburned fuel is in the exhaust? I don't want 3 foot flames. Just a bright flash is enough for me. Thanks.

 

Quite a few used to put a hand choke on the carb and choke it to the point of flooding out, hit a switch, throttle it up and WHOOSH!!! or something like that sound.

Sort of the same subject; I did some work in South Africa, and they install propane flame throwers as a theft deterent!! Not from the tailpipes though...... from the rocker panels.... holeee They are serious about security!!.

 

Are these flame throwers dangerous to your car? I mean, could you do serious damage, even with a well-thought out and tested flame thrower setup?

 

drgnwgn289 has a good point. . .too much raw fuel pushed through a combustion chamber doesn't sound too healthy to me. I think the safest way is to figure out a way to hook up your own 'flame thrower fuel supply' and introduce it into your exhaust pipe with an injector. But you'd need the plug to fire it too.

Since a car was not meant to do this kind of thing from the factory, I think we can pretty much rule out a 100% safe system. 'Cheap Fun' is what I'm after.

 

why dont you set it up to where the motor dumps gas all over the ground and sets it on fire :thumbup:

 

Hey fatslapper might be onto something here. We have a new breed of drag-racing. Contestants line up and take off while spraying their fuel on the track. 3 seconds later, your fuel trail is lit and flames are now chasing your car. The whoever crosses the line first gets his flame trail put out before it reaches him. The loser has to run around town till he runs out of gas.

SPECTACULAR!!!!!! Yes kids, you can try this at home. Hehehe

 

Sounds like fun... When can we start? lol

 

you can get a get a 4 banger distributer and cut off the gear on the bottom and weld on a pully and hook it up to a 12 volt moter run a 2nd battery in the trunk hook up a switch on your dash and have fun

 

I've always heard that you can just run it rich and that that would be enough to blow flames out the pipe, with a spark plug and coil as well of course. Anybody know if that works?

Car Jacking were (maybe still are) very bad over there, and the robbers would sooner kill you than look at you....this is not overkill as many would assume....it is also non-lethal...read the text...

I seen that on the TV. The driver has a little button on the floor that he can just step on hard and flames shoot out from under te car on the sides. I think they said some guy invented it cause there were a lot of road thefts that just stopped you on the highway and jacked your car.

jimmy rig it

take a hot wie run it from the distributor cap all th eway to the back bore a hole in the exaust thread a spark plug in using the exaust as the ground lead the hot wire to the spark plug and bam flamer thrower i have one on my dirt bike

 

How do you get flames to come out of your tail pipe?

A combination of about 50% jalapenos and habanaros mixed in some Cayenne pepper sauce will do the trick pretty well.

Sorry couldn't resist. :spank: :spank:

The price of gas isn't high enough for you?...

Not to sound like an old mother but "waste not want not!" I can't believe people still want to burn up more of their money and give the fuel companies insentive to continue to gouge us at the pumps, Even though it DOES look awsome .

Sorry for the rant but we just hit 95 cents/L CND (Thats like $2.80 US/gal!) My *** sure hurts from taking that one up the ol' tail pipe!!!:embarrass ain:

 

The flame throwers i have seen use a hand choke,it takes a minute or so to get the fuel worked through the exhaust.I'm not sure how they fire the spark plug in the tailpipe,but when they do it will throw a 3 to 5ft flame.Now the guys that get serious use white gas,Coleman lantern fuel,in a pressurized container.When they get the fuel burning in the pipe they add the coleman fuel under pressure.I've seen a moving car leave a flame 50yds long and close to three stories high.Those guys usually lay a piece of fire retardent material across there trunklid.You can feel the heat from the flames in the upper rows of the grandstand at your county fairgrounds:thumbup:
