Elliot has been doing that with water/meth injection for a while

Nitrous removes about an order of magnitude more heat than evaoprating water does.

What if you injected it before the turbo, so it makes the air denser before it even gets toi the compressor? That'd be like having a much larger turbo, for "free".

Cooler air is denser air, but has less volume. The heat energy is actually a big part in helping you spool.

I wouldnt inject n20 into my turbo. Fuel, maybe...not N20. You can potentially have an explosive situation if/when unburned fuel hits the right a/f ratio.

Cooler air is denser, and while it is true that for a given volume of air, a decrease in temperature will result in a decrease in volume, we are not dealing with bernoulli's principle here. The volume, for all practical purposes, is infinity. Therefore, cooler air is denser air, period. The turbo will pull in a given volume of air, and cooler air will be more dense. Therefore, the cooler the air is, the more air mass the turbo will be pulling in for a constant volume.

The heat energy only matters on the turbine side of the turbo. The more heat you keep in the exhaust stream, the more energy is available to drive the turbine. It has nothing to do with the compressor side of the turbo.

Nitrous oxide is an inert gas until it reaches combustion temperatures. It is no more reactive than the air your engine normally inhales, other than having twice as many oxygen molecules per atom. Nitrous will not burn by itself, and neither will air. Nitrous does nothing more than allow you to burn more fuel. Fuel = power. Air only matters when you have too much or too little.

LOL, Disreguard my last post. I misread Heretic's post and thought he meant injecting N2O into the turbine housing.

at high enough pressures and temperatures, air is flammable! that is how oxides of nitrogen (pollution) is formed. too lean, combustion pressure spike from too much advance or compression = NOx.
