Talking Re: The truth about "ram air"
North American P-51 mustang was among the first planes that used LAMINAR wing shapes to assist the performance and flight range [ Berlin ]. Turbulance is lost power and not desired.

Some of the new lennox heat pumps that I deal with have SPECIAL shape blades and FLAT grill fins to reduce turbulence, I.E. Noise. Noise is a sign of turbulence and it is a selling point when the outdoor unit is not so noisy that you have to yell on your own back deck as it starts up.

THis is why I shaved the inlet of the throttle body and rounded the throttle plate as the air velocity is on the order of 175 MPH !!!!!!! Thats big if your having eddies or turbulence form at that point.
