why do you want to spin the water pump faster???????
don't you just want to get the impeller closer to the timing cover(More effective) and turn it slower...........
I guess a street car with a fan blade attached to it.....it would be helpful.../?
In my opinion without the whirling blade of death as I call it on there it's not robbing much horsepower at all. I'm a huge fan of electric fans. I'm tired of that death blade in my engine..
