Strange Overheating Problem
My FF water temperature is pretty much on target while I'm on the track. Typically around 190 degrees while driving it hard.
But, as soon as I pull into pit lane the temp rises rapidly to 250 degrees and the coolant system pushes coolant into the overflow tank and spews fluid out of the tank and through the radiator cap.
Any ideas on what is happening? Why are we seeing this when slowing down into pit lane?
A few things come to mind
The obvious difference between the two situations is decreased/no airflow at pit lane speed vs on track, and decreased/idle speed of water pump.
If your water pump impeller has broken/eroded/not so flashy, it might be pumping "good enough" at raised/on track rpm, but not pushing enough at idle.
The other thing is air flow through the rad - it might be enough at 100 mph, but can't get through the rad at slow speed - bent over fins, buildup of crud between fins, other type restriction(s)...
Hope that is of some assistance, GC

Would a small electric fan to turn on in pit lane be feasible ? Very low current draw. ..
