Because I have a dry sump, I have studied oil pressure extensively on the zetec. At idle spec is 28psi (min 18 max 40 constant), and about 7.5 additional per 1000 rpm.

I got numbers directly from ford, and some from ford UK too. I also have docs that should performance of the stock pump as well as some with aftermarket pumps.
