Typical values for a nice, tight engine seem to be about 40 psi or perhaps a tad more, warm at road speed. And perhaps as low as 25 at hot idle, but those I'm familiar with are more like 30 at hot idle.

Those observations certainly don't agree particularly well with the shop manual which says 35 psi at 30 mph.
