But, that's not how a nitrous system works. Atmospheric air has about a 21% oxygen concentration. Nitrous Oxide, on the other hand, breaks down into 33% oxygen concentration.
Furthermore, when Nitrous Oxide decomposes, the reaction is exothermic. In other words, when (2)N2O decomposes into 2N2 + O2, it ADDS heat to the intake charge (technically already under compression in the cylinder, and igniting). You confuse spraying liquid N2O into the intake tract, which cools the intake charge from evaporation, the same way fuel injection does.
The reason N2O adds power, is because it displaces atmospheric air with a molecule of higher oxygen content, which can be readily broken down to O2, and then combusted with fuel.

Nos has a 1000 psi pushing it your not going to stop the cooling factor. And as we all learn in science class cold contracts heat expands. Nos is -127 degrees in a gas form. -127 degrees is super dense o2 with 2 molecules of nitric oxide per 1 of o2 (That's important). Im really trying here lol for example if I had a basket of laundry and I tried to pour the basket into my dresser drawer its not all going to fit. Now if I fold it it will all go in nice and neat. Unfolded being forced in to fit is a Supercharger, Folded is NOS. Its the same volume of clothes no matter how you get them in there. Think about a 1000psi and -127 degree working together entering the cylinder at 900psi. Compared to just sucking it in with a plain intake stroke. Then look at the product going into the cylinder super dense nos not hot o2. Think about the the explosion created in the cylinder.
Like a firecracker if you unwrap a firecracker it just fizzles if you compress the powder it will explode. The increased amount of oxygen & fuel in the combustion chamber results in the assorted molecules being more tightly packed than normal.
Does this help I don't know how else to explain that a more dense charge will (lack of a better word) weigh more than a less dense charge in the same volume.

its not just getting sucked in there its F/I
Either way you still have a chemical process that happens that
Atmospheric air has about a 21% oxygen concentration. Nitrous Oxide, on the other hand, breaks down into 33% oxygen concentration. Putting 33% of oxygen in the same volume as 21%( N/A) takes some type of F/I whether its chemical(NOS) or Mechanical(turbo-S/C) its F/I
that creates a tremendous force on the rods.
I know you've seen nos cars blow the intake right off from a back fire in a video or somewhere that's not because of a standard 21% o2 cylinder charge. know what I mean, Your getting there but your just not all the way there yet
