‪Light Weight AeroCap Wind Tunnel testing‬‏ - YouTube
Here is some of my wind tunnel tests...
more details are under success stories..and wind tunnel.
I think i'm getting 3mpg more on the highway, i need to get more data to validate this..it is less noisy. And it tilts up from the side for easy acces, tailgate is still usable too. It does get hot, i tried just using the double sided tape the window material came with, but the 100+ heat was to much. The edges need to be duct taped("clear style"). I may go to the boat shop this week and see how much it would be to shrink wrap it with the white stuff.
