I have been wondering how much benefit there is for a cobra running a windscreen vs one running a windshield at the track. I stumbled onto a neat java BHP absorbed co-efficent of drag calculator.

Any guesses to the Cd of a cobra? They list several cars here for comparisson. my guess would be .42?

Now how about frontal sq foot area of a cobra? How does 12 sound?
From that, it looks like on a fast track with a straight away speed of 150mph, the drag sucks almost 116 HP. Any guesses to the size of the windshield? How about 6 sq feet? Would it be logical then to say that a windshield robs about 60HP at 150mph?
your thoughts?
