For those of you who dont know wtf im talking about, or know its better but not why..

Cold air is more dense, more compressed. By using Cold Air Induction, your allowing more air to be burnt at the same time, and more air = good (nos is basicly pure air with nitrogen as an ignitor). Hot engine bay air, is less dense, therefor, the hotter the air, the shitter tha air/feul mix will be.
hope this helps any of you.

-Cold air is not more 'compressed' then warm air - if you compress cold air, it becomes warm
-Air isn't burned in a reaction - it merely provides oxygen for combustion of fuel.
-NOS (nitrous oxide) is an entirely different compound to either molecular nitrogen and oxygen (air)
-The nitrogen released when NOS breaks down acts to prevent detonation - it's oxygen radicals that supply the 'energy'

Other than that, a really useful post

nitrous oxide is pure air with nitrogen as an ignitor

erm what are we breathing in then as nitreogen accounts for roughly 79% of air, while the remaining 21% is made up of other elements such as oxygen and carbon dioxide. Now nitrous oxide formula is NO2 IIRC, and therefore is unlikely to pure air my friend

Actually nitrous oxide is N2O, but yes, you're right - I'd like to see our friend breathe pure nitrous oxide and survive for more than a few seconds...

Is it a diesel engine?

Oil floats on water.... so i'm guessing he isn;t using the water and its sitting at the bottom of his fuel tank....!!! not great.

nos is 33 percent oxygen as normal air is 20.8 percent oxygen

You'd make a poor scientist, NOS is N2O with two nitrogen atoms to one oxygen, but the nitrogen an oxygen atoms dont have the same mass. Nitrogen is 14 while oxygen is 16. So not 33% oxygen but 36.36%
