You do realize it contradicts almost everything you posted in your last post about the P51.

Particularly:

Supersonic aerodynamics and compressibility were still pretty new and not well understood at the time the P51's radiator was designed. Therefore, they did not correctly slope the intake for normal shock formation. The slope was too steep and separation occurred.

That means high drag. This is confirmed in both later NACA wind tunnel testing and RAE flight testing. It is highly unlikely the P-51 series achieved any of its designers goals of laminar flow or Meredith effect. Interesting enough, the B-24 with the Davis wing in a complete accident of fate, did achieve laminar flow!
Hang on, why you're taking supersonic aerodynamics and compressibility into the equation? No plane of the era was designed to operate at such speeds.

My point was that if compared to other radiators of the era, the Mustang one was by far the more aerodynamically efficient, and surely superior to radial engines.

So you're now telling me that the Mustang wing is not a laminar design?
