I wonder if I need a high volume water pump. I have ran two different bb's, 440 and 512 in my car and both experienced the normal 180 temp to rise quite a bit past 200 when idling in heavy traffic and uplining at the track. So far no overheating. Temp cools down when revving or getting up to speed. Two different radiators. First stock 3 row 26". Then alu 2 row with bigger tubes. No change. Run stock water pump, 7 blades I think. Tried different fan clutches. 7 blade oem fan, shroud with the fan about in the middle, 1" distance between clutch an radiator. Playing with timing and mixture makes no difference. What do you think? Any prefered pumps? Was looking at Milodon high volume pump with aluminum housing. Any experience with this pump?
Thanks
