Hey, don't sugar coat it!
A wind tunnel that runs at 85 mph is a great place to do a "cause and effect of a proposed membrane" test on a shape that holds several world records up to 84+ mph as a human powered vehicle (designed by an artist, not an engineer).
A NASCAR team might come in with a wax or silicone application and get a feel for any increase in speed. (Insert Skittle joke here). A race car that hits 200 can have the data scaled up to get an "expectation" of performance at speed. Without side winds.
Luckily, I'm not an expert in anything beyond concept formulation and project administration. I hire experts. The people who read technical essays from concepts that can generate money aren't interested in "opinions," either.
Field testing is the hot ticket. I hope 8080 gets the green light to compete.
