It would have been far better to have spent that money on a hotel in Arizona or Utah and done some decent testing on an empty road.
How about a textbook published by a seasoned professional like Hucho?
Everything I said comes from his chapter on wind tunnels.
And remember, I gave you caveats :
* only 'Streamlined' cars tested
* Tested at zero-yaw
* Curved or Adaptive walls ( A2 has an adaptive ceiling )
* With a blockage-ratio calibration model tested in a large tunnel.
All conditions were satisfied according to Hucho.
* Hucho read all the tech papers in preparation for publishing his book. I know of no revelations which have occurred since 1986, that would overturn his basic premise.
* I've done my testing either at the Chrysler Proving Grounds, Bonneville International Speedway, or DARKO.
