Are these underdrives?
Well I pretty much know my water pump pulley is aftermarket, anyone have any ideas on what brand it is? its 6.5 inches across
here are the other pulleys... can anyone tell if they are stock or not? Mainly I ask because if the crank pulley is smaller it will mess with my boost..

Crank pulley does not look stock. PWR steering is stock, and the water pump pulley looks like a Steeda pulley.
If the supercharger runs off of the serpentine belt then it will effect your boost. It'd be increasing your impeller speed if the crank pulley is smaller. You could get more boost, but you also could over-spin it at high rpm

if the crank is smaller it will slow the speed of the charger... thats what i'm worried about.. I dont want it to make like 4 lb of boost because of this..
thanks for the info guys... anyone else have an opinion of the crank pulley?
