Hucho devotes an entire chapter to heat rejection.His books are invaluable to eco-modders.
My truck has a half-bulbous nose,as per Paul Jaray's 1922 design,as well as a permutation of his cooling system of the same year.It requires a 50-sq-inch opening to cool a 150-bhp engine at 75-mph in the Texas summer heat.
In the fall and winter it can be reduced to 25-sq-inches.
