wont going from hot to cold really fast or going form extremely hot to cold create condensation..which is water...which is bad for engine?

 

The Reason why it wont work is simple. With oxygen itself into the combustion chamber, it induces a hotter flame, but without anything to dampen this and compensate (fuel wise) you will not gain any power. you will gain tons of heat, and destroy your engine.

Nitrous oxide is better because not only does it provide the oxygen, it provides the buffer of cold temps, and nitrogen to dampen it. you usually just plump it right into the intake stream right where the plastic elbow is. You would most likely want a wet system as well because it injects fuel into the mixture as well.

Wet = with fuel
Dry = without fuel

btw, rotaries LOVE NITROUS. Put a good exhaust system on there, and a nice filter, run a stand alone, and run a wet nitrous system and you got a nice street setup that will spank allot of cars out on the road. NOX can be found at at ANY performance shop or dyno tuner place.
