For me it would be extended high speed road run's lasting 30-60min or more.
1) Separate the two cooling systems to keep the engine coolant from heat soaking the IC coolant.
2) Incorporate isolation valves so the IS coolant will bypass the HE during these runs.
3) Create a IC coolant tank that "refrigerates" and keeps the coolant temps to around 35*F - 45*F
4) Make the refrigeration system "electrical" so not to rob crank-horsepower.
Now that's a "chilling" idea....
