Well, I just can tell you what I know for sure. At least in my car, the dyno and the data log reads 13-14 lb. and I've been using this pulley for a while. That was something I was questioning lately, because I read of other members about 18 lb. and unless my pulley has the wrong number on it I don't understand. And a smaller pulley I don't think is possible because of the heat soak.
