And now for something completely different...

I just finished watching the '10 Dakar rally. I kept a lookout at all the cars for what they were using for air intakes. There was only ONE NACA style duct, and that was on top of the front fenders of the VW Race Touaregs. All the rest had scoops, and the Mitsubishi entries actually had scoops that looked almost identical to the scoops I've made, and in the same location, and they need to function at lower speeds in the desert, so I don't know that I'm too far off. I suspect the main advantage of the NACA is its decreased effect on aerodynamics and less to do with flow. I'm not going to be worrying about how many tenths I'll be able to shave, so I think the scoops might be a nice look. Again, I can always very easily convert to NACA later if I need to.
