Nitrogen is NOT FLAMMABLE. It is an inert gas, which means that it does not react to anything. Not fire, not temperature, and not any other chemical.

When nitrous oxide is injected into a running engine, the heat of the combustion causes the nitrous oxide molecules to split into two nitrogen atoms and one oxygen atom. This extra oxygen (which is extremely flammable), when mixed with additional fuel, causes a hotter combustion cycle. The two nitrogen atoms go out with the exhaust, totally unburnt. The flames that are associated with nitrous have nothing to do with it at all. They usually happen because you suddenly let off the throttle, which turns off the nitrous instantly, but not the extra fuel, which will still be injected into the engine for a split second. This extra fuel causes a sudden rich condition and sends a lot of raw fuel into the hot exhaust, which then ignites, causing a flame to shoot out of the exhaust.

Yeah, what he said

yup Murcielago659 ur right bout the whole thing (which is y i said an oxygenator) if memory serves propane can be added to ur fuel (like nitrous is added) and that adds more fuel to the combustion.

in autos we learned how leaed fuel has a high octane (resistance to knocking, useful for high boost/ nitrous applicatinos) and was cheaper than current gas... what im trying to do is locate a leaded gasoline source.. and to the tree huggers, screw the enviorment its damned weather i pollute or not

and finally with the whole flame and exhaust thingy, i honetly would install nitrous or an agressive cam to acheive flame, but if they occur thats fine

Or you could get a Mazda Rotary powered vehicle and remove the cats and install straight thru mufflers.
