John;
If I remember correctly, NACA ducts depend on laminar flow to work
efficiently and by the time airflow over a sports or comp coupe gets to the
rear it's pretty turbulent.
I don't know if NACA ducts are reciprocal-- that is, if they work "in
reverse."

Speaking of experience...
Has anyone ever run reverse NACA ducts...say 2 - 3"er's on the rear deck
of a sports or comp coupe to try and create a low pressure area under
the rear of the vehicle?
