Read:
Engine Cooling System with a Heat Load Averaging Capability
to see why it can.
Note that:
"
- Under typical driving conditions, an engine generates only about 30% of available power for 90% of the time.
- The remaining 10% generally [near peak output] is used for accelerating or climbing steep inclines.
"
So with a sympathetic driver at the wheel (who understands that he will be 'borrowing' heat capacity for an overtake, etc against driving with a light foot later) I would estimate that an 80% reduction in rad-size/grill-opening would not be unrealistic for anywhere but the most hot, arid environments.
