yeah, all your accessories take hp to turn. the most power intensive are the waterpump, AC, and power steering.

the accessory drives were made for ALL vehicles ford produces, including minivans which take a LOT more AC power to cool, more weight over the front wheels, making more steering boost necessary, etc.

Switching to an underdriver slows down all the accessories, freeing up the hp, lengthening the life of the accessories, and giving you a boost in mpg, as well.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
