I'll have just as much fun sitting in the passenger seat nagging than doing all the driving.

What diameter pulleys are you guys using on the crank and water pump?

I had underdriven, but switched to overdriven to spin the pump faster. Can measure tonight.

Awesome! Text me or post the results here. Vince (Vince_GTO) loaned me an aluminum flow cooler pump with the pretty blue impeller last night! Did you keep your electric fan(s) hooked up or go to a fan off the pump?

I'm running the 6.25 dia. crank and water pump pulleys. I had a larger crank pulley before....don't remember the size. After I switched from the overdrive pulley set-up it cools better but I also changed the fan clutch at the same time so who knows what did what. I don't see any need to overdrive my water pump when most of my crusing rpm is 2500-3500.
