i'm gettin' close to my exhaust install.i'm lookin' at flame throwers on the exhaust.i've seen the kits for sale using different combustables.i've been talkin' to the old-schoolers at the shop about this.the use of a spark plug and a switch came up.thread the plug into the pipe,hook a hotwire and a switch to it,build up the back pressure,hit the switch and FOOOOMM!! 8-) WAY KOOL.i don't know.do any of you?

You need one more thing... a gas line to the spark plug.

There's a reason those aren't street legal. They're dangerous! Have you ever seen what happens when you get too much gas flow and it doesn't spark right away? :bomb: :crazy: :onfire:

These things are only dangerous if you don't know how to use them. Right now I am working on selling these things. Currently I have one that kills the ignition so the motor pumps raw gas out to the tail where my spark plug lights the gas off. I have not developed an injected type set up but I do know to make one if someone were to fund the R&D. I have hooked these up on my Elky and I am getting some nice flames, I do have pictures of my car and a set on a '79 Trans Am I helped install. These are the only two examples I currently have. If anyone is interested just contact me and I will get with you.

BTW a switch with power to a spark plug does not work

BTW a switch with power to a spark plug does not work

running 12 v to the spark plug will not even come close to the amount of voltage it takes to jump the spark plug. Usually the safest way to build a flamethrower is set up a switch that kills the ignition. You will need a secondary coil to turn the energy to ac and ramp the volts up to around 40000 to jump the plug. In short, you have to set a secondary ignition up and kill the ignition for the motor after you are on the revvs. This dumps raw fuel/air mixture into the ehaust, add spark and you have flames.

the way with the 12v switch that ive heard of but never seen is that people will use a diesel glow plug. Im not sure of its effectivness though.

personally I prefer the 98% Nitro approach :-P http://www.ihra.com/gallery/IHRAArchives/shirley

But with that said, My friend is in a 50's car club with his 51 chopped and lowered flame throwing Merc...lots of fun!, looks really cool on the Saturday night cruises :)

Even using a coil and a switch will only produce 1 spark. You need a continuous spark and you caonnot flip a switch fast enough to get anywhere. This is why I have spent some considerable time develpoing a Secondary ignition to fire the plugs that can pull 40 amps and throw well over a 1 inch gap. In testing my associate got caught between the plug and ground and I have never seen anybody get hit that hard. He says that my system is more powerful than an HEI. He says it felt like 10 times more power than an HEI. 8O

Basically A switch to a coil and a plug cannot pull enough current to make a decent spark and you cannot flip the switch fast enough to get enough of a spark. My set-up is more durable than the cheap sets and puts out far more power. I have fried many of the cheap sets figuring out how they worked and finally arriving at the design I am currently offering. You can fry cheap sets and risk burning something up or use my really tough set-up that is trouble free and easy to install.

1982 SS,

1) hmmm, notice in my post where i said you have to set up a secondary ignition?

2) if your friend got hit by 40 amps and a spark that could jump a one inch gap (btw, where did you find a plug with a one inch gap?) im sure he would not know what system is more powerful. That kind of amperage (even in short bursts) would knock someone out clean almost instantly.

Furthermore, you can try to sell a flamethrower kit, however, i BELIEVE (therefore, it once again is my opinion) that you have stiff competition. Autolok, an extremely repuitable company already has a kit. http://www.autoloc.com/products/flame.lasso. that is only for starters. To further my arguement, there is not a huge market for hotrodders. For a company to make a descent profit, they usually selll products for every imaginable hotrod, or specialize (this is where you come in) in a few products and provide installation at a cost. Now, if you take into account the small hotrodding population (in comparison to other markets), figure there is an even smaller percent that want a flamethrower, and those who do probably already have one, leaving a huge saturation in this specific market, i doubt that there a a big profit in making a kit. Why dont you just tell people how to make one?

If you want to make a profit in the aftermarket auto industry, it usually intails machinery that not everyone can have readily available to them (for example, a lathe), and offering a service that require some kind of R&D (for example, cam grinding).

Now, my disclaimer. Im 18, write what i think, and shoot off at the mouth. Dont be offended because you think im calling you a lair. Im not. I just think you exaggerate.

robzkool2, look into this kit. http://www.autoloc.com/products/flame.lasso. thier products are generally good. have 1982 SS install it as professional installation is reccomended. :P

Okay here goes

1 To throw a 1" gap simply use an alligator clip to the tip of the ground on the plug. Now pull that plug away from the alligator clip. Presto, 1" gap

2 I should have said that he was holding the metal connector of a plug wire that did not have a rubber boot on the end. He had it in his hand and was not contacting ground anyplace else. That was his account of the amount of power. I have no way of proving that this is true or not and I sure don't want to try that myself.

3 I can pull 40 amps. after throwing a 1" gap I pulled it apart and the components were still quite warm to the touch 5 minutes later.

4 Making any money in this business is not easy. This whole thing was basically done as a "I think I can do this" and I did. I did this at the end of the show season so I did not have much of a chance to show off before winter came.

If you want to buy the Autoloc, by all means go for it, but mine will be less expensive. If you want to try to make your own, go for it. I can guarantee that you won't spend much less time figuring out what works and what doesn't. I have already done the R&D to have gotten this far. If you want big flames I can make an injected set-up that I know will work because I have seen it done with other kits. If you are a real maniac I could also induce a small amount of compressed air (not enough to reach the explosion point), but enough to make a more rocket like flame.

2 coils are my ignition.

I was going to leave this alone but couldn't resist. As stated in the last thread about the same thing these are illegal and unsafe...there is no way to make this a safe kit. How do I know, how about 20 years in the automotive technical field? I also have a little bit of LEO background, if I saw you lighting one of these anywhere near me I would have you arrested on the spot and your vehicle impounded. It is not fair that you would endanger the lives of innocent folks around to try and look cool. By the way, they are stupid, not cool. I have hundreds of car buddies, they all think they are lame.

After seeing a guy almost torch a couple of people at our local A&W on a saturday evening cruise with flamethrower exhaust i came to the conclusion that this setup should be outlawed and anyone using them arrested.You wanna see flames shooting out your exhaust?Try lighting farts.

what they said. I like running my alcohol and seeing the flames out of the straight headers.

Man...! Those flame thingies are dangerous ! Somebody should make them illegal allright! Boy, and everything else that is dangerous too!

It is logic like that, that is behind the belief that guns kill people. Guns don't kill people,... stupid people kill people. I would suggest that just because something has a "potential to be dangerous" it does not have to be made illegal ( that is the approach of the anti-car Clinton/Gore administration took ) Ooooh, cars are dangerous too when used improperly... maybe the same chicken littles should be worried about stopping the use of cars too.

The single thing here is a need to eliminate stupidity... not objects, tools or toys. Since we can not legislate brains, then I guess we have a dangerous world, today, tomorow and forever. Get used to it and quit trying to make anything you have no experience at illegal.

I would like to respectfully ask any one who can provide a real news paper clipping of a story involving a "Flameing Exhaust" causing damage, injury, etc. to post the clipping. Not antcidotal , second hand or it could-a-been -trouble stories I heard from my distant cousin 3 times removed. I would be interested in real stories or cases involving our friends in LEO places. ( pun alert! )

I am sure that the potential for diffculty exists. I also have enough faith in the motor head faithful that when anyone has gone through all the trouble to hook up a set of these flaming balls of fun that that they will have no difficulty recognizing when they should and should not use them.

Please, lets see all the hard evidence that I am sure must exist on these dangerous flame thingies and then the verdict will be rendered by the court of public opinion without the need to make another un-enforceable law like the bunch the Clinton administration passed that did not actually change anything.

Laws don't fix stupidity.

Have fun with your new flaming exhaust!

Diablo :evil: Doug

(PS : I have 3 sets and no problems with any of them ...
To experience is to know... To know is to appreciate ...
or you can fear what you don't know ...)

Doug, law is already in place. THEY ARE ILLEGAL in every state.

Guns are totally different, the holder of the firearm has complete control over over where that round is going to go.

The idiot shooting flames out of the rear of his vehicle has no idea what is going happen to that ball of fire.

Please.....real life evidence, the potetntial for a serious injury is plainly obvious. I don't need for a human being to actually be injured to see the logic in that.

Darwin in action.....

Flames .... Guns .... similar technologies .... similar problems.... both have a person responsible for the aiming, igniting and the subsequent result.

No one with sense fires a gun in a crowd... no one with sense fires flaming ehaust in a crowd or anywhere else that the trojectory is unsure. People handle fire arms responsibly , but occasionally there are exceptions. I take it that if you are a gun enthusiast and don't want to see government interference there because the safe users far out number the the unsafe users... then the same position applies elsewere.

And yes, the news papers have stories about gun related problems. If the problems get out of hand, public opinion will change largely based upon the media and its gory interest in injury and catastrophy because it sells papers. My personal assumption is that the news media would love to hype up a flaming exhaust catastrophy story. I am waiting for people to submit the stories that papers have printed related to trouble with flaming exhausts. I am confident that if there is a lack of stories, then there is a lack of problem. Much like the lack of stories the have any credibility about 1000 MPG carburators, ghosts and UFO's. A lack of identified events indicates that a potential problem area is just that ... a potential problem only and that people are treating things properly and therefore the potential is not an actual problem.

Please submit stories. I am interested and will not refute the evidence, nor will I gloat or rebuttle. If it is a real problem I will treat it with real respect... but if there is no evidence... then there is no problem.... I don't think we should try to fix what is not broken.

Thanks for the forum to chat in.

Your humble observer,

Diablo :evil: Doug

PUTTING ONE OF THOSE ON MY LIFTED RAM CHARGER


BIG BEAR

Hey nice to hear that big bear! love to see some pics.

Use your head and you won't have a problem.

I see there have been no real articles posted. Does that mean that there are only problems when used by stupid people doing stupid things?

I think the evidence speaks for itself.

Just because there is are no articles on concerns does not mean there are not issues with them. I am quite sure that if the same number of cars had flame throwers equipped as there are firearms the problem would be HUGE.

the bottom line is that they are ILLEGAL TO HAVE ON YOUR CAR, PERIOD!

I cannot continue to have a dsicussion with anyone who could somehow rationalize that shooting 4-6 foot flames out of the car is in any way "cool" or even remotely safe.

Question, if the idiots who actually have these things only use them away from others where it is "safe", what is the point in having them? you cannot see it from inside your car, so who are you impressing (not that anyone would be impressed anyway)?
... no one with sense fires flaming ehaust in a crowd or anywhere else that the trojectory is unsure just to refresh your memory.

Show me evidence.

Concerns are one thing, problems are another. People are "concerned" about racing even if it is done at the track. Just because you don't like it does not mean you have to make it tough on those that do. There are those that are anti-firearm and they try to make it tough on those that do it safely. Those who use them (firearms or otherwise) incorrectly deserve to feel the sting of reality. As far as I can tell, don't fix what isn't broken, and a lack of evidence indicates there is no real problem.

Are you really that dense or just have a hard time reading....I already stated that the reason you don't see that it's a problem is that at the most there might be 1 car per city with a system like that. If as many cars had flame throwers as people own firearms there would be a huge problem. You are comparing apples to steak...not even oranges.

I notice you haven’t mentioned the legality issue. I promise if I see one being lit, that vehicle will be impounded…I don’t care where it is or how crowded the area is.
