Yes, that's it. I guess I could have read the links.

I was pretty sure the power requirement would be high.

there tends to be very fast laminar flow across a bare engine lead, this is helped a lot by the masssive intake of air into the engine compartment, the engine cooling fan is sucking 1000s of liters of air per sec into the grill. This flow need to be broken up in order to reduce lift.

Wind Tunnel Test: "43" 1971 Petty Superbird

Gary & Pam Beineke built this race version G-Series Superbird-stable mate to the K&K Daytona-a next generation, 'what-if' tribute to Petty and the '71 NASCAR season that never was.

They took the car to Mooresville NC "Race City USA" to test in the A2 Wind Tunnel. Although a full scale version was never built in 1971 Chrysler performed wind tunnel development on a 3/8 scale model until NASCAR made a rule change for the 71 season that would ban the wing cars from competition. Gary Romberg is the technical director at AeroDyn & A2, and also one of the original aerodynamicists that worked on the wing cars back when they were developed at Chrysler. Notes and data from the 3/8 model were donated to the Wing Warriors Car Club and the Beineke's built their car based off data results from those wind tunnel tests in the 70's. Romberg was on hand to see a project he worked on over 40 years ago get built into a full scale version.

It looks like there was no snow over much of the bed cover in the middle crown area.

And less than one inch everywhere else as it tapered to zero depth upward.

Very interesting.

Here are some snow pictures of mine, click the right arrow to see the sequence. Truck was parked, heavy snowfall with constant 35 mph winds going into the front of the vehicle during the storm.

Concave shapes are not supposed to support air flow/adhesion, that first photo makes me wonder.

EDIT: Added a photo below to explain thoughts.
