Try co2.....just to cool your intake...

C02 would leave too much carbon in the engine. with RX7s that can be a problem anyway so i don't think c02 is any better than n2o. n2o is cold too since it is compressed gas, so the idea of co2 is the same thing as n2o except it doesn't buffer the engine explosions, it just coats the walls with carbon depositing.
clean your engine a lot!

If you want to inject something into your intake, inject water. No, it won't really give you power, but it will clean things out! not to mention helping with detonation! Well, it may help with power some due to evaporative cooling... but thats about it.

C02 does not burn, so it can be (and is) used for cooling. The problem with C02 is that it expands really fast (notice the bubbles in your coke when you open the can) so it would consume all the volume in your intake and inside the engine leaving little to no room for fuel and 02 which the engine needs to make power.

Umm, no.
CO2 is an incombustible gas found naturally in air. The effect of injecting it into the intake would come solely from the ideal gas law:
pV=nRT
R is a constant, and n is the number of molecules of CO2, also constant.
The CO2 would be stored at high pressures in a tank and then when released from the tank would rapidly drop pressure, thus causing Temprature to drop as well. This is also why nitrous comes out so cold (stored around 100 psi at 75 degrees and drops to -127 degrees when released).
As CO2 would not be part of the combustion, it could not result in the formation of carbon.

Carbon formation comes from the inefficient combustion of iso-octane (gasoline). It is 8 carbon atoms attached to 18 hydrogen atoms, so it should not be hard to tell where carbon deposits come from.

RIGHT...so the co2 would only be used to "cool" the air in your intake box. set up a sprayer into the cold air box on your car and just "fog" the box the co2 will cool the air entering your motor.....it would work... I am working on an external nitrogen intake cooler for the intake box and tubing right now....I know the c02 works because that is what i used to test before i spent the extra money on a small 2.5 tank of nitrogen....i'll post my final results and pics of how to.....Or the kits might be availible to buy if i can do them cheap enough and have enough interest...pm me for details...

Interesting, guess i was wrong lol, now that i think about it, something else must be the ignitable gas in those keyboard dusters.

i thought they were just compressed air, that wouldnt ignite
