We actually had this discussion over on the s2ki forums. Someone drew up an autocad design showing the airflow over the vents. Now I'm no expert but this was how it was explained to me. The airflow over the vents would be considered negative pressure. So unless you had some sort of scoop say ala STi or a dip on the hood itself, the vents wont be as efficient in dissipating heat at higher speeds. Again this was how it was explained to me. I hope you're right in this instance
