flame thrower kit

[phatG-A]

ok i wanna know what everyone thinks about the flame thrower kits that you see on ebay motors. not bad. no way or to much like a rice burner. pardon the pun

[ccarr8705]

I would like one but not a regular orange flame. I would like a blue or red flame outta each of my exhaust pipes.

I was thinking about doing this on my next car,but i was thinking about using propane for it. I'm just not exactly sure how i'll do it yet though. :P

[VanishingImage]

just do it like ppl did in my dads era,put spark plugs in your tail pipes(mostly cut a hole and point the ignitor part inside) and hook up a wire to your battery or a switch that is hooked up to your battery and so on,got some flames.Thats pretty much the kit you get in those Flame Thrower kits,just a couple spark plugs and some wires.

You've still got the problem of making a fi engine run rich enough to push the proper amount of ignitible gas fumes out the exhaust. It wasn't much of a problem back then w/ a carb. engine but fi/ that's a whole different story.

well, that was on the old motors w/out fuel injetion... where it was easy to make it run rich, because you have to make it run rich to do this, just putting a spark plug n your exhaust aint gonna do jack, basicly ya gotta take everything out, cat, mufflers.. ect... got to have alot of flow, but if ya do run rich, you burn more gas of course and have to change your oil every 1500 instead of 3000, so an external sourse would be best, but propane will burn yellow, u would need an pure N20 spray... but anyways, yeah!

[VanishingImage]

ahh,very true,i forgot about that....So yea,youd have to find something to spray into the exhaust or purposley run rich all the time to get flames.

[Ghostgt]

How expensive would the N20 be and what color does it burn? i am definently thinking about doing this on my next car! It would be like the ultimate tailgater revenge tool! :lol:

[VanishingImage]

depends on how much of you want/need.If im not mistaken i think you can buy small canasters,like the ones you use on air guns and stuff.I belive it burns blue,not 100% but about 95%.

[Ghostgt]

Ok so here's my idea on how to do this. Drill a hole in your exhaust pipe and have a nut welded onto the hole to screw the spark plug in to.Then take a coil and run a plug wire from the coil to the plug.Next you'd rig up a system that would spray in the N20 into the exhaust piping and you'd have the bottle secured in the trunk like a nitrous bottle(maybe you could even use one).All this would be done at a flip of a switch like nitrous would be. What do you think?:roll2:

[VanishingImage]

yea that sounds like a good setup to me.....The only time i would do it is if there was a civic behind me with a huge wing on it.Which would mean about half of the cars that are around where i live.Even my friends neon with his alum drag spoiler wing.

You can purchase flamethrower kits, IIRC GodfatherCustoms sells them.

But here is a basic setup that works for ANY vehicle, espeically if you remove the catalytic convertor.

Install a spark plug about 6"s in the end of your tail pipe. Run teh plug wire to a seperate coil. Wire the coil to a relay that is activated by a switch. The same switch should activate another relay hooked to the factory ignition so when the button is depressed the it will cut off the factory ignition.

Now when the vehicle is running crack the throttle to WOT just before you press the button. Then the button is press it removes the power from the stock ignition causing the enriched fuel to flow out the engine though the exhaust. Whent eh switch inturupts the stock ignition it also activates the coil for the spark plug in the tip. Once the rich fuel passes the plug you'll get a nice flame out of the back of your car.

You only hold the button for a few seconds and once you let go your vehicles engine should still be rotating and continue to run.

Yes you can us propane but it's more expensive and harder to install.

wow that is one LONG sentance...

Anyhow, what does Nitrous have anything to do with a flamethrower exhaust?

Nitrous is NOT flamable.

I stole this from Don in another thread but it applies here as well...
Notice the green label. 'Non-Flamable Gas'

john - the kits are sold by Auto-Loc

flame throwers are great, if you like rebuilding your motor every year :thumbup2:

Thanks buddy. :) I knew they were made, just didn't know who made them as I have no interest in them. The GN used to blow a sharp blue flame out it's pipe under WOT on it's own. :)

then hows it make your car get hella more HP? i though it was flamabule, it made a flamuabole air mixute then mixes w/ gas and boom, ya fuc kin torch somebody... i guess i dont see how it make more HP w/out being flamable... ?!?!?!!?!!?!?

To get fire, you need heat, fuel and oxygen. N2O provides more oxygen. You add more fuel and you get more power.

To expand upon that, consider that given the volume of air your cylinders draw in, there is a specific amount of fuel that can be burnt. If you go above that limit, you will not be able to burn it and in fact, you will lose power because the fuel unable to be burnt will act as a heat soak. I have literally flooded out a running engine because more fuel than can be burnt is in the cylinder.

Now.. Here is where nitrous oxide works its magic. The air we breathe is 21% oxygen. Nitrous oxide is 33% oxygen and the higher percentage of oxygen is what allows more fuel to be burnt. You have obviously noticed that you can add bigger jets to increase HP levels. Well, consider when you spray, you are merely blending nitrous oxide with atmospheric air. A larger jet increases the nitrous to air ratio, thus allowing more fuel to be burnt and more power.

I see some old myths about the (nonexistant) flammability of nitrous oxide still continue to propogate. Therefore, when the weather gets nicer, I will have to film me opening my nitrous cylinder above into a fire. I guarantee that a big tongue of flame WILL NOT come shooting out of the valve.

So is it possible to make a flame thrower kit using N20 though? I think this would be the safest/best way because having raw fuel run through your exhaust can cause engine problems and you'd have to change your oil more often since it will get mixed with gas. Also the nitrous idea was that you would use the bottle to hold the N20 and that it would be wired up kinda like a nitrous system would be.Travis

No. Read above, Nitrous is NOT flamable.
Spray nitrous though your exhaust and try to light it nothing will happen.
Spray nitrous at a candle and it will blow it out.
Spray it at a blow tourch it might change the color of the flame a bit, but it will not ignite.
Nitrous Oxide is consists of 2 parts Nitrogen, 1 part Oxygen. It's a oxidizer not a fuel.

Using propane is that alternative to cutting the ignition and igniting enriched exhaust.

[Ghostgt]

Any ideas on other gases or a mixture of them that would work?

[Wallflower]

The Auto-Loc kits aren't the greatest to put on an FI car, granted they do work. The problems come after cutting the ignition, loading the cylinder with fuel in order to get it to work. First is the damage to the cat, cut and dried. Second, it will most likely give the ECU a coronary trying to compensate for the ignition cut and fuel overload. And finally a minor issue, loading the cylinder with all that unburnt fuel washes down the cylinder walls of the oil needed for lubrication.

Pick an rpm ... say 4500

4500rpm/60 seconds = 75 times each second that the piston makes a cycle without lubrication. How many seconds does it take to relube a cylinder wall with adequate oil? I dunno, but think about it.

The propane systems are far safer.
