Ersin, I think you are saying the oxygen content is determined by the density not the pressure? Well I think I'm saying the same thing.
The quantity that is critical is the amount of oxygen in the cylinders, by mass. Since the volume of the engine is constant then talking about the density of the oxygen is the same thing as talking about quantity. Pressure affects performance indirectly as it affects density.

Yes, a smaller pulley will give you more boost, we all agree. I was just pointing out that some things that you said were confusing.


Cheers.
