Yeah, tried it indoors racing TC 19/27t on carpet with foams. I had a 30mm hole in the front window and a 25mm hole in the rear window in line with the front on the left hand side of the car so the air flowed over the motor. The motor temps dropped about 1.5'c -2.0'c with the front or rear open, with both open it was about 5'c drop. Didnt look too bad and worked a treat, tried it on a mardave v12 as well with similar results.
