I've always known that turning the belt takes power, without regard to the particular accessory being powered. But how much?

At its most simple, if you could replace everything but the crank pulley with an idler or a tensioner so that no load were being driven, how many horsepower would it take to turn the belt at X,000 RPM (pick a number).
