I am also interested to see what happens when I put a large fan in front of the body. Nothing scientific..just intrested to see if downforce produced.

You not going to get good results but it will be fun to see.

The reason the results are not going to be accurate is because the air entering the wind tunnel needs to be flowing directly at the object and no turbulance. The fan is going to have air going in many directions. I have thought about this a lot and I think you would need to make a tunnel about 10ft long and maybe use small long cylinders for the air to go through before going over/under the object.

Also I think our bodies create a lot of drag which isn't always measured by scales.

I am still interested in your test. Please post your results.
