Wow - great reference! I wish that I had this sort of info when I purchased my first turbo over 10 years ago! Heck, I wish I would have had this when I purchased my last turbo a couple months ago.
It would be nice if you would have footnoted all (not just some) of the references.
For ionstance, some of the references to the same compressor yield different cfm/lb-min ratings, when in fact they should be the same ) barring any mods).
