Several years ago a friend tried adding the various ground affect devices used by NASCAR to increase his cars mpg. He found that the effects at 75 and 80 mph were far less than those claimed at 180 to 200 mph.
I am glad to see you are having results at lower speed.
Got me thinking... and testing more. Here is what I found:
Towing a box TT requires 60% MORE power at 80mph vs 60mph
Towing my optimized TT design at 80mph requires 15% LESS power than the box trailer at 60mph!!
I think I am on to something :)
