He's right mate.
Nitrous is not akin to Water/Meth injection at all.
Nitrous makes power in two ways:
1) The decompressing gas lowers intake temperatures, causing higher densities in cylinder.
2) Nitrous is a moderately stable gas. It will not combust, nor react with any metal or rubber/plastic. However, at 400 degrees (Can never remember if that's in F or C) it decomposes into nitrogen and oxygen. The nitrogen is then just a waste gas, but the oxygen then can be used for combustion. You need extra fuel injected to prevent the combustion goinglean.
Water doesn't actually make any extra power, it just allows more power to be made.
Water has what is known as a high specific heat - it absorbs a fair bit of energy, before its temperature rises. So by injecting it into the cylinders, a lot of waste heat is removed, because the hot exahust gases pass off energy to the water, which does not rise in temperature by as much as the exhaust gasses fall.
By reducing waste heat, you lower the chance of auto-ignition. By lowering the chance of auto-ignition, you can increase boost or advance timing - that's where the power comes from.

That said.
Has anyone tried it to any success? I want to get an Aquamist installed, but the sole distributor in Australia (MRT), says I don't need one, and good tuning means I'd never need one.
I figure if the guys selling it warn me off it, it's gotta say something.

This would be true if i was talking about JUST water injection, but im talking about alcohol injection (with some water added) it also boosts the octane levels ( like nitro, but not as much) and if the water is mixed right it also is in an unflamible state (depending on the proof, up to a 50/50 mix is still not flamible with out high heat)
the alch will raise the octane as well as drasticaly lower the temp (even better than water due to its low boil point) So, it does "add power" in the octane sence. but also lets you increase timing & boost because it prevents detonation...
Aquamist is a very cute apllication, but i have seen the SMC one in action and it works very well
I guess these three solutions are it ?
