as most of u know, N2O has cooling effect when burned, meaning less chance of detonation
You said it cools when burned... it's not burning when it's coming out of the bottle.. its decompressing.

When nitrous is under pressure it has a cooling effect. I think it had to do with the chemical makeup of the compound. When i let nitrous out of my bottle it always freezes the area where it is coming out of.
Physically, it doesn't have anything to do with the chemical composition, it has everything to do with the fact that its compressed. When you compress a susbstance, you make the molecules closer together. Molecules that are closer together have less room to bounce around, and thus can hold less kinetic energy(heat)

When it reaches the cylinders, it's already expanded, so the cooling effect is probably minimal... Besides, when you ignite it you've got more fuel+air so you get a larger explosion (more HP) and thus more heat.

Completely no offense, but "nitrous is cold when it comes out of the bottle, therefore engine temperature is lower so there is less chance of detonation" sounds like an defense of n20 from someone who doesn't really understand whats going on inside the engine. That type of person is the type most likely to wind up with a toasted motor.
