I'll be doing some distance driving for Thanksgiving and will start calculating fuel consumption.

Here are some photos of the holes I plugged up.

I think that would work on a S-10 Blazer very well, but could look a little weird on my truck. I'll be thinking about it, thanks for the idea.



Does that data mention lift? The thesis I found talked about a lot of lift created which is typical of drag reducing devices.

Do you have anything on roof wings verses these flush plane spoilers?

I think my current state is acting as a wing, but I require more seat time to be sure.

Reduced lift was a side benefit of the drag reduction.I don't have the paper with me so I can't give you any particulars.
