I can see how all of this can be relevant to a NA engine, but in the case of a turbo charged vehicle, where the air is pressurized and the engine is being force-fed air rather than just sucking it in, would the results be any different?

Remember, outside air has pressure. When the engine develops vacuum to draw in air, it moves because of the difference in pressure. If you apply boost to the intake, you can think of it as an artificial way to make a very, very high ambient air pressure. It flows because of the difference in pressure, only the difference is much greater.

there's another proponent of combustion chamber turbulence. a man by the name of somender singh. http://somender-singh.com primarily for otto cycle engines i don't know if we could even use these ideas. something to look at though.
