Why do you think nitrous is so cold. Its the process of expansion into a gas that creates the endotermic effect.
So bottom line its physics nitrous will flow as a gas trough your intake period. Its flow charactheristics should be very similar to air and quite different from fluid.

True true the nitrous changes from a liquid to a gas at 20*c about 70-75*F. But it does not change at -88.44*C it changes at 20*C.
Here is some info from NX

The "dry" system uses the factory fuel injection to enrich the nitrous introduced into the engine. The flaw with this technology is that no matter how much nitrous arrives at a certain intake port it always gets the same preset amount of fuel, or if a fuel injector becomes clogged engine damage will result. The "Wet" technology introduces a precise amount of fuel and nitrous through a high tech mixing nozzle that atomizes the fuel to microscopic proportions. This allows every cylinder to receive a precise, homogenous mixture of fuel and nitrous, thus insuring a safe, powerful increase.

Nitrous backfires can be caused by two situations. 1. A nitrous system that is two rich or a system that atomizes the fuel poorly, thus causing pooling or puddling of fuel in the intake manifold. 2. A system that is operated too lean.

This is what I was originally talking about, the wet kits are no more dangerous than a dry kit and if anything safer in the hands of a person that can be reasonable while using it. This is just my opinon and no matter what anybody tells me I will never use a dry kit.
Also one thing I forgot to mention was that the dry kits produce less hp than the wet kits. I tried to find it but there is a dyno test between a NX system and a ZEX system and both were jetted for 50hp. The test car was a civic SI or civic SOHC, and the results were the ZEX kit produced 38whp extra and the NX kit produced 51whp extra. I am pretty sure about the numbers, its been a while sense I have seen it but I do know that the ZEX was in the upper 30 whp range and the NX was either 51 or 52 whp.
