any body have one on there trucks? I've always thought it would be cool wth stacks. Could it be done with just a coil and spark plug or do i need to imject something in it?

 

iv done it on a muscle car how i did it is i wired a cutoff to the coil for the motor, and another coil hooked in that would come on when the other went off, i had spark plugs in each pipe that were wired to the aditional coil, so basicly what would happen is you would rev it up and it would cut ignition to the cylinders wich would cause it to pass all the fuel to pass threw the exaust and be ignited by the sparkplugs, i doubt it would work on a diesel, maby if you installed a auxilary small gasonline tank with a fuel pump and install an injector in the exaust and then you would need somthing that would create a quick on off pulse to fire the coil for the spark plug

 

i just hauled a flame thrower car 2 days ago it was a 68 bonneville called (bon evil)

 

Ya, it'd be tough... they do it on cars by cutting ignition. we ignite by compression. you'd have to have an auxillary injector in the tailpipe as well as a spark plug... wouldnt be easy, and im sure im missing a few things here.

 

What if you did it with propane? inject it right into the exhuast. I always wanted to to this. Hope you find a good way so you can tell us and we can do it lol good luck

 

Propane burns fast- you'd have to do it near the tip to see it!
That or dump a huge amount in!

 

Do it with propane.
easiest way to do it. YOu woudlnt' want to dump fuel into there, it would be a pain to get it to jet.
It would be super hard to do. but i'm sure its possible.

i'd probably dump it in behind where i ignite by 4 or 5 inches, maybe further to make sure it mixes with the exhaust and the exhast pushes it out, isntead of it being pulled out by passing air.
Then ignite it with a hot spark plug. As long as you dump propane it should go pretty good. *shrugs*
Propane is finicky.
