I have a feeling that the opening angle of the floor register is too sharp and the incoming air becomes too turbulent, thus affecting its cooling capability.

Ford used angled grill bars on the original Fiesta. Their testing showed that at higher speeds the boundary layer would thicken between the bars and the air would skip right over for improved aerodynamics. I hope you find a workable solution. Something that would only open after the engine is up to temperature would be very beneficial in cold weather.
