forward deck flow

Bill Bernstruch,one of the videographers who has attended Bonneville and El Mirage events put a VHS together long ago which included a 914 at El Mirage.
As the car makes it's pass you can clearly see the dust from the lakebed coming up and forward over the rear deck,completely filling the void all the way to the roofline,and within it,you can see a tranverse vortex circulating above the cooling inlet slamming dirt through the hole.
A K&N wouldn't last 2-seconds inside there.
I suspect that this could be witnessed on any Beetle,Ghia,912,and 911,and it's an intentional design criteria for the air-cooled engines.
