cop cars actually have smaller pullies that increase the output at idle. the upgraded cop package of the 80s on fords became the mainstram parts in the 90s as ecus, nice radios, power windows etc used more juice and became more "standard equipment."

to see a real gain you either need to use the smallest alternator you can get away with, OR use a high power alternator that only runs when you are decellerating. i dont know how to take one apart (and get it back together) to put a switch to turn off the field. there is a thread about it and from what i see is they just remove the darn thing and run a bunch of deep cell batteries. If someone is a rebuilder they can probably do it. id pay a guy to put some sort of switch on there to operate it by choice.
