I doing a 2 speed intercooler pump setup. Run the pump powet through a resistor so that flow is slow and water stays a long time in the FMHE. I have vacuum switch that closes when there is a lack of vacuum which will bypassing the resistor giving the pump full power (14 volts)

I want the coolant flowing so that the line is cold right before the intercooler but I don't want my intercooler loop heating up.

When you get into boost your radiator and supply hose are cold.
