i think that they are f ing sweet but how badly if at all do they mess up the car, and what is the danger factor.

[Siggy_Freud]

If you do them right, they wont mess up the car at all. There is always danger with fire bud. Cant really get around that one.

As long as its done right its safe. Like anything, stupid people make it dangerous.

If you value your engine don't do it.
The type I know interrupts the ignition so the raw air/fuel mixture floods the exhaust system where it is ignited at the tail pipe by a spark plug. So far so good. But what do you think the raw gas is doing to your cylinder walls? Its washing away all the oil, that's what. No lubrication spells big trouble very soon.

[Siggy_Freud]

lol true but thats not the right way of doing it. You can set it up so the gas (or whatever chemical you choose to use) is fogged into the pipes via fogger nozzles and solenoids.

Before attempting to do such a project, consult tutorials and as much info as you can. I have done this project before and it worked great and was as safe as could be made (I mean you are dealing with fire here).

HEY CAL; You might take a peek at your insurance. Some policies are null and void if car has flame throwers. We had a couple at our Downtown Cruise In one year and next day I got a call from local police wanting me to come in and show proof of insurance for public liability That was last of flaming boys DAVE

My $.02.

I think they're kind of dorky. When I see one, I think they rank up there with a continental tire and fender skirts on a dragster.

I think there pretty sweet too but wouldent it like melt your back bumber or leave black marks or sumthin like that

[Siggy_Freud]

It all depends on the setup. My pipes on my pickup stick out a few inches out the back and I only fire them at a higher rpm so the exhaust gasses have some velocity to them.

[Mightymouse]

Sweet.. about how big of a flame do u get on average??

[Siggy_Freud]

Depends on the velocity and amount of fuel being injected. At idle they are about a foot. At 2000 rpm 3 feet or so and above that you get into the 4+ foot range. It really depends on your setup, pipe sizes, amount of fuel being supplied, at what pressure, etc.
