Porsche 911 Ducktail - Study/Alternate

Waiting for the snow to melt so I can take some field measurements of a building, so I cut up a business card and compared a Ducktail to an alternate location a bit higher.

Would be made of clear Polycarbonate or Acrylic.

Not sure yet what would happen with the flow/vortex and pressure level above the engine cooling inlet.








This is a side-by-side comparison, would not double Duck, although I guess one could.

As I understand it, the Ducktail, Teatray, and Whaletail all try to correct the approximately 30 degree roof angle to mimic an approximate 20 degree slope (almost like a louver - steps).
