I knew some people would be upset when I suggested that flat underbodies don't really work that well (if at all), but considering people were killed and exiled for figuring out the world was round, I think I can take some unwarranted hate myself. =P
As far as the hood vents, if you wanted to make them effective and not ruin the cooling intake, you could design them (point them) in a vector/line toward the sides of the car so the warm air could roll over a minimal area of the intake at the windshield.
I don't intend to anger people, just put what I know out there (teaching, sharing info... same thing or not? I don't know).
Sorry for seeming 'arrogant' or 'claiming to be smarter than everyone' or 'not taking credible sources seriously' or whatever. Hucho got a bunch of stuff right, but he isn't the only guy out there with some good knowledge on how this stuff works.
As I've said many times before, I'm just letting you guys know some stuff I know. Believe it or not, that's up to you, but you probably aren't going to change my mind on what I said in the first post. mcrews, would you like to contribute something useful to this forum? Don't bother us if you have nothing useful to say.
There's a reason Formula 1 requires a flat section under the car: it lowers top speeds because of the huge amount of drag it creates. In no way shape or form would the F1 engineers choose to put that flat surface there on purpose.
