Sure there is,, All you have to do is get pulleys that are larger round or smaller round. I'm running a large on my crank and a very small on my waterpump. That way it increases the water pump speed at an idle. and since I was using this truck as an off road truck and doing a lot of slow speed (VERY SLOW BUT NOT ALWAYS) DESERT driving I needed to keep the water moving in the radiator. To save the horsepower do the opposite.
