Vortex presence
On You-Tube, there is footage of the Bramos Racing Team's 'winged,' Porsche 911 in the A2 Wind Tunnel, undergoing smoke-flow visualization.
You can clearly discern the longitudinal vorticity, off the C-pillars, attacking the rear wing, and surviving beyond the wing, in spite of the wing's capping plates, which are conventionally understood to 'kill' tip vortices.
Hucho has stated that pseudo-Jaray 'fastback' vortices are the strongest, and longest lived, among all body types.
