Seems to me that people are posting actual numbers and not guesstimates. I think that we all agree that engine temps have a lot to say performance-wise

I guess I'd assume whatever a stock vette runs is pretty close to ideal? GM engineers could set the car to run at basically whatever temp they want when they designed it so I bet the numbers it runs at stock are about ideal, for our blown cars I'd guess maybe 10* cooler on the coolant temps than stock is ideal perhaps to keep cylinder head temps down. So my car seems to run ~180-185 on freeway and 190-200 in traffic, not sure what ideal is but my car comes up to 165 very quickly when started cold but then just stays 165-185. I'd think oil temps are more critical than coolant temps, and I wouldnt like to see oil temps >250ish for any extended time
