Run electric fans all the time?

Run electric fans all the time?

I asked CVF Racing about their aluminum pulleys and this is what they said:

With aluminum pulleys you can only make the water pump pulley neck down to about 6.9" before it comes in contact with the bolts that hold the pump into the housing. With that being said, now you can only make the crank about 6.4" before it becomes too big and touches the water pump pulley. So the best ratio you're probably going to find is about 0.92:1. And we only do that combination with a two groove crank. Our single groove crank stuff is all underdriven because they are typically high horsepower race applications and aren't concerned with cooling or charging.

I looked at the stamped steel pulleys on there now, and the two rims are just about touching. The outer groove is for PS pump which I don't have. So the (inner) crank pulley would have to get bigger at the same time the water pump pulley gets smaller... Not only that, the water pump pulley can't get very much smaller either before hitting the pump bolts on its
ID.
Now what? :realcrazy:
