I've got some reading and thinking to do. Can this even be done on a bike? The P-51 Mustang example stated the Meredith Effect worked at 430 MPH duct speed.

Hoerner published the thrust for the cooling system on the Messerschmitt Me-109,I don't have that with me,but again,we're looking at a 500+ mph aircraft where compressibility effects are active,not so in low speed aerodynamics.
Also,imagine the maximum heat flux coming from a V-16 aero engine at max power setting.
