As you well know, this pulley (and the patch of belt it is in contact with at any given instant) is trying to transfer 30-60 horsepower in order to compress the air (and subsequently burn the rubber off our tires )
However, some don't know how critical the pulley groove profile is to this .... hence my 2 cents

Cheers,
