The idea could be used in a normally aspirated car by just using the external air source (or a compressor for air suspension). It was to be manually actuated as I thought rigging it up to a pitot tube would be too ridiculous. Never ended up building it, but I did write it into one of my books, not that that's a proof of concept, but I can't see why it wouldn't work.
Yeah, I was thinking of all sorts of active grill blocks. I have at least one mechanism that I know will work (my Dad made it while helping me on an Energy Design project at UCLA), but it would be a lot of labor to make it work just right, and I didnt' want to run wires if I didn't have to. What I am trying to do is make it a "semi-active" system that uses the air pressure to my advantage.
