"Tuner", whatever his name is, posted a link to a research paper from the 1960s that a group of Japanese engineers did that covers extensive computer modeling vs test results from an experimental carburetor on... emulsion. The correlation between them was very good.

I have a hard copy, but will see if I can find the link and post it.
