Perfect weather, 2mph from the south. I selected a section of 288 that was almost perfectly North-South with a 5-6 mile run without overpasses. It was a Sunday night a week ago, so traffic was minimal. Still, when there was traffic, I didn't make a run until I thought that if I did catch the car in front that I'd still be at least 10 car lengths behind when I popped into neutral.
Made 3 coast downs north, and three south. Took the lid off and repeated that twice more. Put the lid back on and did the north/south runs once more.
Also, I did go thru and screenshot the before and after weather and there was no significant change in pressure or wind direction/speed. When I got out to take the lid off and replace it I can tell you there was no air movement at all both times. And each time I got out of the truck my glasses fogged over immediately.
And I really can't think of anything that could have changed the test parameters that much, which is really, really disappointing. The thing took 7 or 8 builds to get right; it's durable, safe (didn't rip off at over 100mph), and shows no signs of wear, warpage, or photodegredation. It kinda hurts to think that I can't get a test to show SOME positive results.
I even considered just ripping the damned thing off. I figured even a 5% drag reduction should show something, even accounting for the human (I can't hear, she can't see, and we both love to fight) error. Glad I didn't though, I think that San Antonio trip at least shows I'm on the right track. I guess I'm going to have to do the test again.
Oh, and thank you. That's a very kind thing to say considering my own kids think that it looks funny (the manky little heathens just don't understand art).
