Yep. Picture a big pulley connected to a small pulley with a belt. Each time the big pulley rotates once, the small one will be rotating several times.


Maybe a clutch or flex fan instead?

I went with a locally produced one from CVF Racing. Nice piece, and it's really helped reel in long idle temps so far --but that was my goal and may not be yours.
