LMAO Phil was never without hist trusty ciggie so a built in lighter was an obvious accessory

Nope it isn't nitrous, way too dangerous for that kind of stunt. it is a flame thrower that uses unburnt fuel in the pipes and ignites it with a small spark plug.
Billy Lane did one a while back that actually had a fuel line and injected raw fuel into the hot pipes to vaporise it and a plug to ignite it.
That threw 6 feet of flame out of the back lol.
I can build one into Black Beauty for you if you like mate
