[DeTomaso] Pantera Aerodynamics

[Tomas Gunnarsson]

Regarding pressures over the front end of the car, check this out:

Scroll down a little and a couple of pictures showing cars with front end side profiles not all that different from a Pantera will appear. The pressure profile along the roof is also interesting even though the back of the car is not like on ours.

The top of the hood is shaped exactly like an airplane wing, and probably generates an enormous amount of lift all by itself; the trunk isn't strong enough to resist deformation at those speeds.  You could try adding material to the front trunk weatherstripping (that is, adding another layer of stick-on weatherstripping on the top to ensure a good seal with the hood) and see what happens?Some vendor's carbon fiber units are often much, much worse in this regard.  Even vented carbon fiber hoods aren't strong enough, and will bow enough to pop open above 100 mph.  Geoff Peters threw one or two of them away before buying one from Sigbjorn in Norway that was properly made.
