Turn your car into a weapon of war!!

Maybe it's just me, but I can't believe any responsible person would:

a) Buy one of these
b) Install one

SWEET. That's actually a new concept to an old upgrade, with the way it supposedly burns the unburnt fuel already going through your exhaust. The old systems actually used fuel from your primary or a secondary gas tank to provide the flames.

I thought that with catalytic converters, we can no longer use these on our (newer) cars?

That's a good point. The cat should significantly reduce the availibility of unburned combustables. Flame throwers whether commercial or home made depend on lots of unspent gas in the exhaust.

I want one on my motorcycle. Tail-gaters BEWARE!!! LOL

Yeah batmans one of them

Oh ya...............the first time I saw one I was 16 (21 years ago). I used to cruise my car in Dallas and this guy had one on his old Apache Truck............I thought it was the coolest thing ever...............

Thanks for jarring that memory centennialman!!!

saw a flame kit on a turbo CTS. when he hit it the flame was gas stove blue, about 3 inchs long. looked like the afterburner on a fighter jet, very classy,very cool.

he was using it at the drag strip during his runs, made the car seem that much faster than the 12 sec. slips it was turning in.

i would do it to my classic if i could get the same effect

My biggest gripe with these systems (they are awesome to see though) is that the ignition gets killed at high RMPs dumping raw fuel through the motor. Can we say cylinder wash anyone? These systems are notorious for causing premature engine failure and as of late it seems that is the last thing Aurora lovers need. Don't get me wrong though, I would love to have one on an old unsuspecting beater.

How does it work? I just assumed it was completely external to the motor.

Typically a spark plug (2 for duals) is mounted in the tailpipe about 3-6 inches back. An extra coil or two is mounted close by. A switch and relay are installed to kill power to the coil(s) running the engine and divert it to the coil(s) in the rear. You rev the motor up to high RPM's and push the button/flip the switch. The unburnt gasoline passes into the exhaust system where it is ignited at the tailpipe instead of inside the combustion chamber (meanwhile raw gasoline is washing all the oil from your cylinder walls/rings). You simply let go of the button/flip the switch before the motor stops turning to get it running again. The result is a wicked flame shooting out the tailpipe and a motor left wondering "now why the hell would this moron do this, I thought he/she loved me". I was thinking about this last night and thought why not just mount a fuel injector you could command on when you wanted to shoot flames. With some ingenuity you could build a pulse generator to cycle the injector and the separate coil as a standalone and still leave the motor running. No unburnt gas in the combustion chamber or catalytic converter sounds like a winner to me. Plus you would have constant pressure pushing out the tailpipe that would cause the flames to shoot much further than expected and not burn up a plastic bumper. Just my .02

Most of the kits now use a fuel injector near the tailpipe rather then killing the ignition. The modern catalytic converter would commit suicide in no time it if the system was used more then a few times. The only thing from keeping the flames getting really big is the lack of oxygen in the exhaust.

In theory a well managed system would add a few horsepower by pulling a vacuum on the exhaust. That is my theory at least.
