Seeking advice.
Today I thought for sure I would see an appreciable decrease in drag. My sample was only 15 miles but any improvement was negligible. I have a 4 sided box 66" long at 16 degrees. The entry cuff is curved HDPE at about 11 degrees. The top is 16 degrees. There are vortex generators on top & both sides.
The Zevo is 84" W. The WT doors 'aperture' @ 50"W.
I cannot do a tuft test because I do not have a partner/chase vehicle.
Included are 6 photos and a video. Thoughts?
