If my interpretation of my limited reading is correct, a similar system (to Valvetronic) is used on the MINIs.

The wedge throttle sounds intriguing. The idea could be extended further, so that there is only one gap for air to go through at all times, instead of just at very low throttle openings. The slide valves used in some race cars would be one way to do that--the throttle plate slides out of the way instead of rotating out of the way. The intent in a race car, of course, was to eliminate the restriction from the open throttle plate, but it would give you only the one opening.

Perhaps an iris? That would be quite mechanically complex though.

Neat ideas to play with.

I look forward to seeing the results of your testing!
