By this I mean hard data (numbers) like Cd, lift, drag etc. vs. speed and aero configuration.
Thanks,

As a start there is AI:
The drag coefficient (\(C_{d}\)) for a Shelby Cobra coupe is estimated to be around 0.28, which is a significant improvement over the roadster's estimated \(C_{d}\) of approximately 0.5. This lower drag coefficient is what allowed the coupe to reach much higher top speeds.
"Estimated" I have done wind tunnel work on motorcycles in the Wichita aircraft model tunnel and in the Modine (truck) cooling tunnel, where we built a venturi to get the airspeed to 120MPH.
I have reviewed the Penske "rolling road" tunnel in Mooresville NC where they test scale models, mostly for NASCAR teams. A very expensive process.
As a DIY project I would do models.
