Intake tracts don't just flow air, remember. They flow an air/fuel mixture, whose behaviour is quite different from plain air.

Gotta respectfully call you out on that. That was true with carburetors and TBI systems, but not port injection. The fuel is spraying right at the backside of the intake valve, the intake tract is only passing air (and crankcase fumes when the PCV is open) (and exhaust when the EGR is open).
