Not necessarily, the sweet spot for Evans to reject heat is a little higher than a normal coolant, but once there you can load the engine pretty good and not see the same increase in temps from there. FYI with the below, but the link for this article is now dead.
Circle track racers: "Running higher coolant temperatures makes sense if you can control it, but what effect does the higher temperatures have on
oil temperatures? Evans' answer comes from his testing with Detroit's automakers. Evans said, "Chevrolet is now saying we should be running the
oil temperature at 220 to 240 degrees. If you're not, you are giving away horsepower. We have learned to stay below 260 to 270 degrees because the life of the
oil starts to fall off. The people who run 180 degrees need to know that it is not good for the bearings. The oil is too thick. The rings are plowing through it and the pump is pushing it, both of which rob horsepower."
