OP -- Vortexes don't work that way.

What I'm curious about is your [proposed] wind tunnel. What scale will it work at? Most are 1/4th to 1/10th; but the horsepower requirement goes up*. There was a guy in Japan who had videos on Youtube showing his work at 1/24th, but I think they're gone. He had digital scales under each wheel and one to get pushed at the back. He couldn't derive absolute values, but could do A-B comparisons.

*There are losses involved, so a full scale wind tunnel will consume 1000s of horsepower.
