If it worked and it's ROAR legal you'd have even more interest!
The new Roar rule book does not have a section for this, but the old books said that if the real race car had it, have a picture of it in use and it was ok. I don't know if this still stands or not.
With a basic wind tunnel (made from a large box of straws and some cardboard,) it gennerated 5gms of additional wieght to the front tires on each side and 11 grams of weight at about 45mph wind (based on stihl backpack blower ratings) on each side of the rear. More with a stronger air flow and less with less air flow. (tested both ways, with and without aero package. 3-5% increase in downforce. HAS NOT BEEN TESTED ON TRACK IN A RACE CONDITION.) So, does it work,? Hoping to do some track testing this weekend if the rain holds out in Tampa.
