Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???

I didn't catch what kind of engine and how much power it makes ----???
hi h.p.engines create a lot more heat than lower engines do...


Back then I was making around 400 hp. This time it will be 500.

They don’t make 1000 hp at idle so horsepower is a bad way to rate a cooling system.
