i think you have the idea right, but under compression in a turbo charger and intercooler you have heating and cooling of air, it is hard to get a air tumbling under 1 bar of pressure. at the rate at which air is going into and out of an engine, all that matters is how quickly and efficiently you can get air into the engine.
sort of right....
smooth walls means air "doesnt" stick to them, air moves quicker against air, so having a slightly roughened surface is better for air flow.
its boring as a lesbian in a bad mood. i left to get a job.
more details then alot of people will comprehend, but yes +1 for that.
i suppose it is another reason why generally larger bore engine create more torque, is that the air can move more turbulent in the chamber, before igniting...i think.
