(OP)
Does anyone have a good reference work for throttle body design? Things like blade geometry vs. airflow rate of change, how bore size and taper affect performance and IAP sensor readings, opening cam theory, etc.?

A throttle plate is not round if you lay it down on a surface. In the closed position it is tilted about 15 degrees so it has to be machined round in that position so it matches the bore.
That is the extent of my knowledge about throttle bodies. I hope there are some more replies.

Are you more interested in butterfly throttles, or other designs like barrel, roller, slide, shutter, etc.?
There is a good bit of information available from those who work with each design for racing use, but there is no "bible" of written work that I am aware of.
I have found a few tips and tricks using IR and plenum throttle bodies that make a good bit of difference. But each require a different approach. And what looks good on the flow bench or dyno may not always be best on the street or track.
Blair and assoc. had an article in Race Engine Technology Magazine on CFD of bellmouth design that is interesting. It is available zipped in pdf form at http:
