Interesting...... Wind does crazy things... But so hard to test at home. Almost need to make changes, then compare ET slips. MPH would be the huge indicator
Then you have to make sure conditions are the same between the runs/days. A light breeze and its direction would throw off the numbers, not to mention compensating for temp and humidity differences. Also have to consider the weight of any mods and what that takes away from any aerodynamic benefits they may provide.
Yea, aerodynamics does weird things. A good example is what the turbulence does in the bed of a pick-up.
I don't know what they were looking at or for, but here is an interesting example of what Chrysler did searching for aerodynamic advantages in the early '70's. They also drooped, chopped & channeled the front ends later trying to keep up with the smaller brand X cars. But you can probably find more tips that could be applicable from researching vehicles in Nascar, Bonneville Salt Flats, Can-Am, etc.
