Ford Ranger wind tunnel test

[Big Dave]

Hey, Corey. I have a prototype (crude but effective) that I’d drive to your tunnel for some testing.

Our wind tunnel in the past had one of the companies producing a type of gator net come in to try and validate their "10%" fuel mileage improvement their marketing department had out. Yeah well it was more like 10% decrease in fuel mileage. Needless to say they left the test not so happy. Just a little bit of knowledge for you.

Hi. I have a '96 Ranger Super, and am interested in the tonneau cover/air dam combo you used. Do you have specs, picture or model?

Clev: follow the link in the original post.

There's an image of the truck in the tunnel - you can see the front air dam - looks like roughly 6 inch depth. Tonneau cover looks pretty standard - what you can buy anywhere.
