I note the grille on the AH 100-4 is higher than is the opening on a Cobra. In addition the leading edge of the hood is higher and the hood itself has less front to rear slope on it than a Cobra hood. I'm not an aerodynamics expert, nor do I have access to a wind tunnel, but I believe the combined effect of these differences is quite significant.
Yes, the windshield pressure wave will affect the rear of the hood, but there are other factors at play.
