Not having a throttle plate is not necessarily an advantage. It could also be replaced by a windmill. I'd really like to see an Eaton electric supercharger used as a generator as well. The numbers on my envelope are quite encouraging.

Production gasoline cars are running 14:1 compression ratios these days. That is getting pretty close to the 16.5:1 in my Jetta TDI. Also the higher the compression ratio the harder it is to meet emission standards. VW has been dropping the compression ratios in their diesels.
