***6 Blade Water Pump vs 8 Blade??***

The factory installed 6 blade water pumps on the AC cars with a pulley ratio that would spin the pump/fan faster to get more air flow through the radiator at low speeds. The non-AC cars got the 8 blade pumps and different pulley ratios that would spin the water pump and fan slower then the AC cars. I run the flow kooler water pump with the non-AC pulley set up.
