Some folks spend a lot of money to loose HP when they fight to run only 180 degrees or even worse yet 160 degrees of coolant temp! The big oval track guys run 200 degrees coolant temp or more because heat is power and the internal combustion engine runs on hot expanding Gases! Just look at the break down of it. 20% of all the heat generated gets radiated off the motor. 20% gets dumped into the cooling system. 25% goes out the Exh. 35% is left to spin the flywheel! Gee , Turbo charging looks like a great thing, no? Lol!
