shoot flames

so i was watching TRUCKS today on TNN and they put a flame thrower kit on an old truck. it seems simple enuf. what you have to do is get rid of the CAT and run an ign. coil off the battery with a toggle switch in the car. install a spark plug 4-6"s from teh end of the exaughst and connect to the coil. taking the CAT out will allow all the fumes to burn on contact with the spark generated by the ign. coil thru the spark plug. its that easy. im gunna try it, but heres a Q....how hard will it be to cut out the cat and replace iwt with a straight pipe? and will it make my exaughst much louder?

I remember seeing this on the list sometime before. I dont think it is possible with our cars, but im not sure. I cant really remember the reason why though. I think there was a kit thought you could by that would possibly work

i think you might also want to turn it off from time to time.....u know.....like when you're stopped near some dry leaves or driving on grass for whatever reason......or if u have little kids standing behing the car before you start it...muahahaha. I heard that there was another way to do that but this was a REAL flamethrower (They use them for car-jacking security in south africa or something) --> the idea is that you get another windshield washer spray system and install it somewhere in your car and have a button switch it on and off from inside. then you place the jets on the sides of the car, or wherever you want the flames to come out of, in your case the exhaust.....and then using your extra ign. sys, you put the plugs in the end of the tube by the jets, or just after the jets. u'd have to find a way to secure them. then fill the spray tank with gas or something flammable and away u go. there's obviously a lot to condsider here and i'm not a pro in any way.....I always wondered though: with this setup, wouldn't the spark ignite all the gas and then like blow up the spray tank? hmmm.....this is what i get for listening to my 9th grade crazy ass science teacher

I too Seen Trucks.

THe Kit they used would not work with our cars because we are Fuel Injected and Run Multiple coils.

 

The way that one works is it.

you Rev to 3500+ rpm

Press button

Gounds out ign coil and sends the power to the Rear Coils.

then you pump the gas it then Sends the gas down your pipe to the end where it then Lights with the spark PLugs.

 

 

what I would say is go to a Ricer Forum and say you want to do that on your civic and ask how to mount it.

 

I know there is a way to hook up a safety valve and a gas line to it so the gas is added to the exhaust and the coil is not gounded on you engine. I seen how to do it about 3 years ago but cant remember how now.......

but the other parts are the same.

 

I would say Just check out the Ricer forums. and then bring the info back here.

another way that I've seen it done...

Install a small bottle of propane in the truck and have it leak into the exaust...

you can keep your exaust system 100% intact...when you want to flame on...open the bottle a little bit...and ignite with a spark plug that you have to mount on the pipe..

you will get blue flame that comes out straight...

It shoudl work on our cars regardless of the efi and such. internal combustion engines arent very economical. as for the plastic rear, its ok, my exaughst stickes out about 2.5-3"s from the top of my rear bumper

this is all good and well, but why would you want flames coming out of the ass of your car? it won't make your car faster......maybe just gayer...but yah ok, none of my business.

what i have seen and what i have seen on my car is that if the car is running very rich. then you will get some flames. when my exhaust gets hot and im on it real hard i can get a nice blue flame out the back. Just my 2 cents

We used to shoot flams out the side of my dads truck (had no cat, no mufflers, and custom side exit exhaust right after the cab) by running some racing fuel (112 octane) and putting it in 1st gear, and revving up. It would shoot a 2 foot flame out the pipes

My first reply in this section of the forum!

 

This months Automobile magazine has a kit in the shopping section for flamethrowing exhaust. Looks simple and straightforward. I believe its $125 for a single exhaust setup and $200 for a dual exhaust setup.

On my old cutlass (carbed) i just put a switch that diverted power from my hei to a coil in the rear. The pints were taken care of by one of those trucker fans

( imagine how fast the points open and close on a brush motor!!) so the plug fired a million times a second, and all i would do is rev it to about 3500 rpm, hold it steady, and push the button...about the time i would have to hit the button off to keep the engine from dying it would shoot out a few puffs about 3 or 4 feet long! It would literally rock the car! But then agina i had a 10.5 :1 compression 1968 350 rocket in my 84 Delta 4 door!

Vintage cats 2 inch single exhast and still flames! the bad thing of it this way is it dilutes your oil!

 

Now my 97 cutlass is another story. I have a fleetguard etherinjection system, and one of the 1 lb propane bottles mounted up. itll be better then my delta!

If someone wants cheap parts, and info email me ..

SEAN!

Hey dan...how ya been??!!!

sorry...im in the midsts of building a bigger better flame thrower, and im digging up old stff!! LOL!

 

So i guess people jump your ass when you make unnecisary topics, but also when you actually use the search and find and old post, huh? I replied to another old one, and someone popped me on that too.

You will need something to pulse the power to the rear coil, weather you use the stock wire and kill the power to the engine's coil, or you use a motor like mentioned above. You can even build a special circuit for it, and its not too involved. Just grounding it to the battery will not work because of the nature of electromagnetics.

 

As for flamethrowers, I have built a few. I plan on putting one in my other car, but in the meantime this is a standalone one I built with a friend last summer:

And no, a tank filled with flammables wont explode because there is no way for the flame to get into it. There is no oxygen in the fuel line to make it burn (fire needs oxygen...) and thusly cannot travel up a tube filled with liquid
