The impeller on water pumps can cause problems; loosen on the shaft, or corrode, reducing flow. Some pumps (not Saab) have plastic impellers that can deteriorate and crack, and some cheap aftermarket units are just poorly designed from the start.
My bet would be on your radiator. Don't overlook your hoses, though, suction in the cooling system at high speed can cause a hose to collapse and restrict coolant flow.
