Are you going to do A-B-A testing at the track to see if there is a difference?

I'd be suprised if your under hood temps are 200* while you're moving...you're still getting airflow. I can't see an outside air supply adding 65hp+ just based on air temps.

Somewhat unrelated...my Coronet was on a string of 10.50 passes one night at QC when the W023 scoop came off in the shutdown. Next pass, no scoop, just a carb and a big hole in the flat hood, car picks up .08 and 1-2 MPH. Only thing I can think is the carb pan sealing to the hood, and the size of the scoop, were creating a pocket of positive pressure and causing a ton of negative areo drag. No more air pan on the carb for me.
