Stock Water Pump Pulley Vs Underdrive Kit Water Pump Pulley

[92GreenGT]

Hey guys, I bought a BBK Aluminum underdrive pulley kit awhile back. Then I bought the blower so I had to put the stock crank pulley on. I cant find my stock water pump pulley, so I just left the one that came with the kit on. I cant remember if its larger or smaller than the stock pulley. Which is better to have? I want the most flow from my waterpump, so which pulley would be better? Thanks

i would guess since the stock pulley is bigger it would turn the water pump faster and you would flow more. but there is no real way to tell try em both if it runs a little warmer then swap em back i plan to run a elec water pump.
