If it is dead center of the car it may be the water pump rather than the radiator. GM deliberately chose not to put in an upgraded rediator in the ZR-1 and designed the bypass system to protect it from the higher GPM that Lotus designed for the car. Lotus spected the pump to flow 25 gal per min per 100 hp which is close to 100 GPM.
