yo, people have a look at this just getting one.

I had one, it's called "key banging" and it works so much better with the origional exhaust

but back to it, my friend made his own for his car and it was heaps mad and saved him that 100+ bucks

My first car was a '65 Plymouth Fury. We had great fun with a similar trick, only it was not a flame thrower, it was a fuel/air bomb. After the car was warmed up you would drive up to 40mph, turn off the key, let the car coast down to 35mph, then turn the key back on. BOOM!!!!! A fireball a couple of feet wide would shoot out the end of the exhaust accompanied with a very loud explosion.

Turning the key back on ignited the fuel air mixture that was filling the exhaust system. Doesn't work on the newer cars with idle cut solonoids or fuel injection.

A standard muffler was good for about 100 explosions before splitting wide open. When you were getting to the end of the usefull life of the muffler you could hear a whistling sound from normal driving as the seam in the muffler was starting to unroll...

i've got a BBQ starter, the little thing makes a spark, would that work?

therefore wont on datsun with regard to young bloke below

Quote:We pulled this stunt in a 1949 Ford Pilot [British postwar version of 1936 Ford V8] These had a dual exhaust as standard & we were coming past the Gaol in Parramatta.
Ignition off, madly pump throttle & pull out choke. Then choke in, throttle part open & ignition ON.

The resultant explosion split both mufflers wide open & gave it a throbbing exhaust note to be proud of. I have no idea what the reaction of the guards in the towers was as we didn't hang around to find out, but we had visions of finding bullet holes in the back of the car when we got home, but fortunately, ... no.

When we stoped laughing at the condition of the mufflers, we all chipped in & bought two more used ones from the wreckers, but stayed well clear of the Gaol in that car ever after.

What you have to do is hook up some spark plugs near the end of the exhaust and run power to them with a switch. Choke pull up the choke and and hold the switch for a second or 2.

There's a little more to it than that but meh, someone else can fill in the blanks

whats with the need to shoot flames out the back anyways??
get yer mate to hide in the boot with a lighter and a can of wax and grease remover.

Or just retard the ignition... Or buy a rotor

Yeh the old spark plug in the tail pipe is a old trick. I think you hook it up to a coil aswell and just have a switch to give the coil powah! Flick it on and off and you should be flaming like a true champion in no time

Hmm i have the welder at home and i have a spare coil in my shed... Flame throwing 720 bunky! It'll be good coz i think it had a fuel leak to
