idk some of the muscle car guys say its best to run around 195-200 for the engine's sake. says that is when the oil is heated up the best to full lubercate.
this is what he had to say about it, it was for a turbo guy but same concept.
Detonation needs to be controlled with octane and proper fueling/timing. Running a block too cool can lesson ring seal and cause piston scuffing as the piston to cylinder wall clearance may not be tight enuff on a cold motor. 200 degs is good for the track. Hot oil also allows the turbo to spool faster...hot tranny fluid allows the converter to stall higher as well. If you arent running hot, work on keeping those IATs down.
i run the stock thermo right now and my car does not get all that hot.
