My car nearly pegs 150 psi when stone cold, quickly drops to the 90 range,
then at full operating temp, runs at about 60 psi at speed, 15 or so at
idle.  Drops to around 45 psi if I head the oil up much past 220f or so,
and will go up above 60 if particularly cold outside.. your figures don't
sound too strange, other than 85 psi at 2k - if that's with a fully
warmed engine, that sounds too high.
