Coolant the engine is discharging vs. radiator outlet temperature.

A resistor is a lot less than $200 and cant burn out.
If you spend $200 plus the cost of the pump which is in the $160 to $500 range the part about the mod being economical is long gone.
I am sticking with resistors.

Smaller engines don't have this, its called a bypass blocking thermostat. Smaller vehicles have a bypass that flows all the time and a thermostat that opens when the coolant gets hot. When the thermostat is open the bypass coolant is still going.
Even on vehicles with a bypass blocking thermostat they still have another bypass.
