1997 7.3 Ford Powerstroke Flamethrowers - YouTube

Sorry if it's been posted before, I thought it was pretty sweet.

 

I saw that a few days ago. Kinda think its lame. One stack gets significantly less fuel and exhaust than the other.. They flames are unpredictable and unequal. Kinda seems pointless at that point. If you could control when they flare that would be great. He cannot.

 

I beat it would scare the crap out of that Prius lady from a couple of weeks ago

 

Propane piped to the stacks with a spark plug.
