Jim,

In my experience, when you have a glowing red turbo, the cooling system is working really hard, especially in a non-T44 car with already limited cooling capacity.  Turbo converted cars need upgraded cooling when driven hard, the turbo dumps a lot of heat into the coolant, and its gotta go somewhere.
