@6pk2goDemon so your original combo was an A/C water pump(6blades) under driven with 1:1 aftermarket pulleys.
With the current set up, are you spinning the pump at a factory AC ratio, or non-AC ratio?
Original combo was a 6 blade AC water pump with a matched pair of 6 1/2" diameter billet aluminum pulleys, so yes 1:1
Current ratio is 1.26:1. Not sure if that's the factory AC ratio or not?? There is some info on that earlier in the thread posted by other members. All I know is it works.....:)
