Need help with flame thrower kit

[Shag Wagon]

A friend give me this flame thrower kit and I dont have a wiring diagram for it. All I got was what the pic has plus 2 spark plugs. Im not sure what I wanna hook it up to but it just might be the wagon since it doesnt have a cat. So does anybody know how to hook this bastid up?

First let me start by explaining the theory behind the flamethrowers. I had one that worked one way and we installed one on my friend's 240sx that worked a different way.

First way is a sparkplug that is screwed into your exhaust tip, hooked up to a coil, which is hooked up to a monetary push-button switch. You push the button, sends 12v to the coil, presto you get a spark at the plug. Rev the engine to about 3-4k, push the button, rev again. Small flame at the exhaust tip. I was running header/test pipe/2.5" exhaust....the flame didn't occur everytime. If you have a catalytic converter, it won't work at all because the cat will burn up the unused gas.

Second way is similar to the first, sparkplug in the exhaust tip, hooked up to a coil, which is hooked up to a switch BUT unlike the above method, is also hooked into the ignition which will cause a delay, dumping more fuel into your engine "in theory" dumping more fuel into your exhaust. This extra fuel will give big flames. You rev the engine, push the button, rev again, shoots flames. Works better than the above method but you run the risk of engine damage from the rich condition.

Yes, they are illegal, that's why you don't do them while driving. Be in a parking lot or your driveway.


Now that I have that out of the way, let me tell you WHY it will NEVER work good on your car. These things work GREAT on turbocharged or nitrous-induced engines because of the A/F mixture. More fuel required to run a turbocharged engine means more fuel dumped into the exhaust....take out the cat and you have more flames than an N/A car. You can get it to run rich easier, which can STILL damage your engine. Nitrous....well, nitrous is highly flammable. You can see why this will work. Without either of these two, you will never shoot huge flames.

Another thing to consider is this....there are additional ways to hook the flamethrower up. Some include running an extra fuel line directly to the exhaust, you hit a button to send fuel down, the spark ignites it, you rev the engine and flames shoot out....big huge napalm-flamethrower like flames out of your exhaust. This is dangerous.

You can also hook a propane feed into your exhaust, ignite it at the tip, and nice propane flames. Wouldn't want to do this either because you run the risk of it back-feeding and your propane tank will go KABOOM and you'll be seriously injured or dead.

That concludes Flamethrowers 101. Hope I covered most of it.

Sweet....but I need a wiring diagram for that little black box.

lol, sarcasm eludes you my friend.

Yea I am that kind of person that needs a blueprint and breakdown as to how to wire something or put something together. Need to know what colors go where.....


BTW this isnt going on my wagon. I dont feel like melting my back bumper or getting sued for torching some guys civic. I might hook it up to my lawn mower or moped or something.
