To get the full benefit of this system, (or even our factory setup - but more so with this type) you should wire your IC pump to be on all the time - otherwise when the fan comes on at lower speeds - (when the SC & IC pump are off) your coolant is no longer flowing and taking advantage of that extra airflow.
While the coolant in the radiator might get cool, the coolant that's trapped in the Intercooler only gets hotter.
I found running the IC pump all the time to be a huge advantage in keeping the IAT's in check.
Tech inspection, whats that? Oh you mean where those young guys take your slip and write a number on the window after walking around the car once.
All kidding aside, do you think the s/c coolant(separated from engine coolant) is going to get hot enough to need room for expansion?
Good point on the i/c pump, but mine is on soon as i start the car. Does it ever not run when the car is running? Are you suggesting to wire it to an accessory so that it stays on when the engine is off? Help me understand.
