I did a quick search of the forum and didn't find a definitive thread where somebody dyno'd their engine, pulled the pan, and then re-dyno'd. Probably because it's such a nuisance to pull the pan if it's not a two-piece. All the threads quote the dogma that the pan tends to hurt more than it helps, but none cite any real tests or evidence, just the usual "all the engine builders say that blah, blah...."

I would think that you'd have to find a way to provide a temp differential to see the true worth pf the pan. There will likely be a drop in power with the pan on vs. off - the question is does the cool air it alleges to provide overcome the loss in power due to theoretical restricted flow? I don''t know how one would test for that. A fen on the nose of the car in an ambient room isn't likely to provide the the temperature differential between the underhood area and the inside of the pan that a car under power on the open road would probably have.
