Thanks for posting to this thread -- I'm building a 1/4 scale model of CarBEN and I'd like to build a wind tunnel to tuft test it. The model is 41" long at it's longest points, and 16 1/2" W x 16 1/2" H -- does this need to be 38 sq ft opening? That's a little more than 6' x 6' ... and then how long would it need to be?
