Default Aerodynamics

I noticed that the factory 5 car.....(the "racer") on "Bitten By the Snake" shows marked inflection of the hood at higher speeds. In other words, the hood was raising markedly in the center near the windshield and let air escape at higher speeds. At first I thought...........Geez. Flimsy fiberglass........but given the discussion regarding air getting trapped under the hood, does it make sense to set your hood up so there is some play? For example, if you didnt latch it down, and there was excess "trapped" air......it would simply exit in front of the windshield.........that is what appears to happen on the Factory 5 car in the video. Presumably at any speed, the hood would find its own balance point. Oh. Yea........I dont do that much racing....guess that could be a little unwieldly in a spin, huh......so it would have to have a safety catch to limit lift........

Anybody know what Dick Smith's car had? I am sure it had a front spoiler. I am very curious about the aerodynamic issues. Anything that could be done to get these things glued to the road would be a huge plus. Louvers could be placed along the inside the the front......basically in front of the radiator........under the chassis??



It would be very interesting to see some testing on one of these to see where the problems arose and where drag and lift were created.
