Does'nt the Space Shuttle and NASA keep fuel cold for launches?
I have seen some drag cars use a canister with a coil of metal fuel line so they may fill it with dry ice to cool the fuel.

So the same principles do not apply correct?
Air:
Nitrogen N2 78.084%
Oxygen O2 20.947%
Argon Ar 0.934%
Carbon Dioxide CO2 0.033%
Neon Ne 18.2 parts per million
Helium He 5.2 parts per million
Krypton Kr 1.1 parts per million
Sulfur dioxide SO2 1.0 parts per million
Methane CH4 2.0 parts per million
Hydrogen H2 0.5 parts per million
Nitrous Oxide N2O 0.5 parts per million
Xenon Xe 0.09 parts per million
Ozone O3 0.07 parts per million
Nitrogen dioxide NO2 0.02 parts per million
Iodine I2 0.01 parts per million
Carbon monoxide CO trace
Ammonia NH3 trace
Rounding things out it's 80% N2 and 20% O2, and that was probably the basis of the original statement that people are picking nits over. If that's the case, then the statement wasn't really wrong at all and the objections are/were just a bit anal.

In the sense that fuel is burned, they're the same, but there also significant differences. In the case of a rocket using LOX, LOX is colder than the dry ice used to chill gasoline, and not only that, the LOX provides the oxigen for combustion, so the idea of cold air or fuel to increase charge density really doesn't fit into the equation. Rockets don't suck in air to make power so things are quite a bit different.

Do you own any WMD's hahaha?
I have been on B-52's that were loaded with nuclear weapons, but i never had the urge to take one of the things home.

Hahaha, I prefer something more precise and selective. WMD guys drive Hummers so they can run over anything that gets in their way; I drive an S2000.

but this is also why it's hilarious that people pay extra to put pure nitrogen in their tires instead of plain ol' air. driving around daytona or indy for 4 hours straight: yeah it makes a difference. driving down the block to get groceries and pick up your ankle biters: not so much.the statement we were picking nits over was
Almost one fifth of the air is Nitrogen

Thanks, Red MX5. I made a typo, and I got jumped on for it. I meant to say Air is almost 4/5ths Nitrogen. The rest of my post reinforces this. I'm not offended by the comments - when I realized my mistake I called myself a few names too.
The real benefit to cooler intake air is that the air is denser, therefore more oxygen enters the combustion chamber. This allows more fuel to be injected, therefore more HP.
