Actually,your post reminded me that, in my original post, I was not quite correct. NA's will suffer significantly at higher altitudes, say over 11,000 feet as they will not aspirate enough oxygen for good combustion. It was this phenomenon that led to the developement of the supercharger on aircraft engines.
