For a given viscosity, the engine RPM is going to be the biggest contributor to the oil temp rise from shearing inside the bearing. If the engine isn't revving at redline, it's probably much less than a 50-60 F rise. I'd say it's more long the lines of a 25-30 F rise (if that) if driving around normally.
This engine flashes to 4100 rpm coming off the line (snapping the throttle from 850 rpm idle), shifts 1-2 @ 5800 rpm falling down to 4800 rpm in 2nd, shifts 2-3 @ 5600 rpm falling to 4700 rpm, and crosses the 1/4 mile in 3rd at around 5300 rpm. Not crazy high rpm. I'm also somewhat worried about aeration since the viscosity is in the 30-50 cSt range for much of the run.
