Has anyone ever seen those kits you could buy that would basically allow you to have flames come from your tail pipes.. I think it had something to do with spark plugs or something. Anyone know where I could find more information about this ?

 

Funny you asked this because I work at a Honda Motorcycle Dealership and we have these guys (one may be related to me ) that own Valkyries, the big *** flat six cylinder bikes, that have the same thing. Its a big *** sparkplug tapped into the pipes about one foot from the back and when you let off the gas the sparkplug ignites and gives you a big *** flame (depending on the amount of unused gas) Its pretty crazy especially at night!

They are legal believe it or not......

 

damn! the only time i wish i didn't have TPI....

 

Also you CAN'T have a catalytic converter on your car for this kit to work......It stops the flow of fuel for emissions....

Here is a pic of them in action....

 

That looks like it would melt the bumper on these cars.

 

There is a way around that. I've seen street/Hot Rods at car shows where guys have ran propane to the tailpipes for extra flame! VERY impressive flame!

 

WEll here is a picture of a kit that wouldn't melt the bumper it produces a blue flame sort of like one of those butane lighters.......

 

You can atcually make one your self for only about $0-15 I was gonna buy that kit but found out their like $100 or so...and $15 sounds nicer. haha

 

That company is nuts. Who the hell would pay that much, then still have to go out and buy half the crap. What a scam.

 

How do you make them?

 

its realy pretty simple to do. all u do it get two nuts the with the same size thread as a spark plug, then u drill a hole in each tip about 1 foot in front of the exit. then weld the nut to it. get some very heavy gauge wire, and an old spark plug wire then conect the end of the old spark plug wire to the new wire. with the new wire runing to a switch in the cab that goes to the battery . then u just srew in the plug, snap the plug wire on then hook up the switch and the power wire and ur ready to shoot some flames. hehe

Have you tried this before???

 

if you have a cat converter, what would fuel the fire??? and what is the power source for the spark in detail?

 

i dont care what it costs or what other people will think ... i plan to get the expensive kit from *** father customs so i can shoot flames at people i'm racing once i get the procharger setup going.

 

i know a guy and work with him and he has a car that throws flames. his biggest i think was 65 feet i think. but he has the spark plugs hooked upped to his big *** tailpipes and then he has sometimes either 2 small propane tanks or 1 huge propane tank that he uses.

 

Learned about how it's done in physics class.. well, not the actual flame throwers, but how spark coils work. Those classics usually pull their choke cable to run rich, then hit the switch for their second spark coil. From what I remember of 6 years ago, When the primary voltage is interrupted, that's when the secondary side of the coil releases it's energy in the form of a spark- and ignites the unburnt gas. Whenever I've seen it done, there's usually a friend with a fire extinguisher standing 20 feet off to the side of the car.

I would just like to know how the Fast and the Furious got all 4 of those cars to shoot flames out of the tailpipes in the "first race". Unless the imports were backfiring?

 

I think that was my ultimate question as well.

 

I think to sum up that movie would be to say, HOLLYWOOD!!!

 

It actually does happen in real life, when someone driving a tuned turbocharged car lets off the throttle real quick they can spit small flames out the tailpipes. Its something to do with the cars running rich (and you can tell by all the black residue on the tailpipes of turbocharged cars). I've actually done it in my mustang (well someone told me they saw it). But as far as that movie, who knows ... they prolly had a special flame kit installed (most of those cars were fake POS anyway).

 

no i have not personaly tried this, but my grandpa has done this to a good number of cars( he used to repaint cars for a living back in the day this is how my moms first car was a 67 ss 350 4 speed arrrgggg i wish my mom and dad would by me one for my 16 th lol but they only payed 650 for it then painted it black with white racing stripes and turquise leather interoior) but now that a coil was metioned im positive u have to wire one in there too my granpa is on a trip and should be back in a few days so ill ask him for sure when he gets back

ttt...So whats the DL... Why cant a TPI car run this set-up..IS it possible to do it with TPI?? How do u rig up a propane to shoot out instead of gas?? Is it safe to do propane?

 

***edited to prevent 'flame' war...hahahaha***

 

Aww man I missed the message before it got edited

 

1st off, you need 2 coils, one for each side.

2nd, most nuts wont let the plug stick into the pipe far enough
its best to use a helicoil. Just drill the exhaust pipe and
then thread the helicoil in. this is were the sparkplug goes
Make sure you put it about 6 inches from the end of the pipe

3rd. Mount the coils on the bottom or frame of the car close to
the spark plugs. Then use a short coil wire to connect.

4th You have to rig up a swith to the two coils and another one
to the one for the engine. The switch to the rear coils
turns them on and the one to the motor coil turns it off
This means the plugs in the engine will not be firing.

5th Start the car, start reving the motor, turn on the switch to
the back coils, then start flicking the switch to the coil for
the motor on and off.

6th set back and roast some hot dogs and marshmellow

Oh yeah, these companys have relays/switches that cut out the voltage to the engine plugs. Its made just for this setup.

as far as propane, you can weld fuel or brake lines into the exhaust pipe and run it to the bottle. You will still need the coils and plugs.

draw backs is that the fuel that is not buring in the motor is washing down the cylinder walls and doing damage to the rings.

 

It's more difficult with TPI because you'd need a custom prom to run the engine rich enough to make decent sized flames. It's easy with a car because you have direct control over your air/fuel ratio via an adjustment screw. As far as the propane, it's fairly safe. Think of using it as similar to nitrous oxide. There's inherent risks with it, some of them pretty serious. But done right, you usually won't have a problem. I know in Reno or Vegas (I don't remember which one) they have a big car show and they have a flame throwing contest. Those guys are shooting propane and getting 60' no problem. Some I think get as high as 75'.

As far as the post above about turning off spark to the engine, I've seen people do it that way before. But if you think about it, the last thing you want to do is be racing someone and turning your engine off and on.

In regards to the propane injection, I've also seen people (it was someone on this board that did it to an s10) have the propane line run parallel to the exhaust tips, so that it lookes like the flames were coming from the tail pipes, but they were actually coming from beside it.

Hope that helps, sorry for the long post.

 

Here is proof that a fuel injected car can do flames without any engine control 'mods'.

FYI - ALL Berettas were fuel injected. No carbs at all.

AS i remember, the voltage for the spark comes from the electromagnetic field (created by running current through the coil) collapsing.

A circuit like this should work

+bat -------- (switch) ----------- + [coil] - -------| >ground
......................................................|.......................................
......................................................|........................................
................................... __________S.P._____
...........................tailpipe_________________/.......::::xXXXXFLAME!!!!

(Omit periods, for formatting purposes only)

with the circuit closed, current running through the coil would create the magnetic field. when you flip the switch off, it would collapse, causing a spark at the sparkplug. So by flipping the switch (or maybe a tapping a button where push-in=closed circuit would be better) you could be creating sparks like crazy, without interupting the engine in any way.

Now how you're gonna get the fuel there is another problem. Fuel injector? Nitrous solenoid?

LOL if it works out that easy, i might just try it

 

What would be even better is after the switch you install an oscillator. That way the coil would turn on and off at a set rate (whatever oscillator was used). That way power would be supplied to the coil when the switch was on, and the oscillator would disrupt it automaticallly.

The reason that you would want the engine off is that you'd be getting a lot more unburned fuel out the tailpipes, since none of it is burned in the engine. I think there's better ways of doing it through. Like a custom prom, or fool something like the coolant temp sensor into thinking the engine was still cold so that it'd add more fuel.

 

errr Dante.. that picture looks an awful lot like you lite a fire on the ground near the back of that car then took a picture.. how come the flame are coming from the ground?

*cough FAKE *cough

 

Go to the webpage attached in that post... you'll see.

 

DOH! and these are legal.. lol

 

I think you'll find these are legal to have but not to use. Technically you can do anything you want to the exhaust after the catalytic converter. But I'd like to see you light up at a stop sign in front of a cop. I bet you almost anything they'd impound your car on the spot.

 

They did a full install and how to do it on "Trucks" about a month ago...The biggest thing you have to remember is you need to wire a kill switch for your motor that stops ignition and lets raw fuel dump down through the motor. On Trucks they had the Power Loc kit witch had the kill switch wired in. Then the 2 coils at the back running to plugs in the pipes....I got this episode on tape!

 

If I read that post correctly, that seems like if your motor is just turning over, but not firing, and fuel is dumping in, you're gonna need oil changes quite often to get all of the gas out of your oil...

 

man i love the flamethrowers on cars.....check out this car......saw some pictures of the guys flames.....u can actually see them sitting on the car.....

 

man was that a cool rod and customs show in pa......ha, its where i got my rims .......check out the pics in the hood.....badass!!!

 

flamethrowers arent really my style, but check out these videos:

i was talking to a guy i know that has done this to his fullsize blazer on 44 inch boggers, he said he had fuel lines welded into the exhast about 4 foot infront of the plugs, then had a 2 gallon fuel cell with a electric fuel pump hooked up to it, he said it would empty the 2 gallons in about 30 seconds!!!!!!!!! can u imagine that flame???? ill see if i can get a pic of it in action some time.

That'd definitely make quite a show......

 

Ok, so what your telling me is that I can legally shoot fire from my tailpipes and catch the car behind me on fire, BUT I CANT PUT BLUE NEONS UNDER MY CAR WITHOUT GETTING STOPPED AND TICKETED?!?!? WHAT KIND OF CRAZY CRAP IS THAT!Sorry, just dont see the problem with neons....but fire?! C'mon!

 

OK, I can't resist posting about The Fast and The Furious....Talk about POS cars? How about the guys green SEVEN SPEED import on the intro. Yeah, let's all order a 7 SPEED for our cars, too, eh? Just listen and watch the shifts on the intro, quite funny.

 

I want a 7 speed they make them for formula 1 but just as a semi automatic.

 

alright, i always seem to be the one that bitches and goes against the grain, so i won't change for this post. Flame throwers are bad *** on old hotrods and stuff, if i had some pre 60's car that was pretty tight, sure, i'd be all up for it. Then the type-r kiddies got ahold of those kits, and now you guys want them? C'mon, some things fir the musclecar image and some do not, this is one of those that does not. Flamethrowers are for hotrods, leave'em that way. If i saw a guy rollin down the highway in anything but an old caddy or buick or something, i'd laugh my *** off, and probally call the fire department. Next thing you know, some of the type-r kids will be watchin TNN and see a demo derby on tv and decide it's bad *** to have straight pipes straight out of the hood because they shoot flames...wtf are all of you thinking, this is just plain wrong and degrading and obnoxious.

 

i saw one of those flamethrowers on a vw beetle

 

There is one thing that has been missed in this entire discussion and its a biggie. You MUST have a perfectly sealed exaust. you cannot have any leaks in the pipes or the headers other wise when the exaust ignites (unless you are doing something like a napalm launcher at the end of the pipe like most of the big ones do) if there is a leak behind the point of ignition there is the risk of the combustion running back up into the engine. Not good. Just somthing to thing about.

 

I'll say it again, these may be legal to have, but I can't image they'd be legal to use on any public road. Just like the neons, they're legal to have, but don't be driving around with 'em on. (Although we all do anyways ) Next time you see a cop, ask them if it's legal to shoot fire out of your tailpipes. I'll bet they laugh their *** off at you. Oh, and in regards to the undercar lights, the reason most cops will let you off with just a warning (at least around here) is that most of them don't know what part of the vehicle code it violates, they've just been told they're illegal. Just some food for thought.

 

Flames are very sweet! :hail: :rockon: After reading all this it is very tempting to rig it up...

 

A friend of mine back in high school (before we had cars) had a souped up lawnmower. That thing was so awful, it was bright yellow with black flames and all kinds of stupid things to "make it look good" We wanted it to shoot flames out of the custom exhaust we put on it and we used a 4 banger distributer and wires it all to a spark plug in the exhaust and then we got a windshield washer fluid pump, put it in a small take or kerosene in the front of the mower and ran a small tube back into the exhaust pipe a little before the spark plug. It would shoot 6 foot flames straight up ( the direction of the exhaust pipe) and it looked pretty bad a$$ at night time. just press the button to spary the kerosene and then spin the distributer and it was crazy.
