Under drive pulleys

Any1 out there heard of a manufacturer that can supply under drive pulleys. These are pulleys that replace standard items on the end of ur crank (aircon alternator), what they do is increase the power output of ur engine to the wheels because they are made from light weight alloy so reduce the drag on the engine. They are really big in america. U can get them for fords (sorry 4 swearing) and have seen somewhere on the net that a focus fitted with one received an extra 5bhp? Don't know if this is true. All the kids in america (uh-oh) are fitting them on their Hondas and the such. I realise that u probably won't be able to get off the shelf units 4 Alfas but someone somewhere may know a friendly engineering firm with a cnc machine that will be able to copy the originals and make up some new ones in Alloy. Any ideas or comments???
