I searched but can't find anything about this. Can the pulley on the blower (not the alternator) be removed without having to remove the supercharger itself from the car? I wanted to get the 3.5" pulley but wanted to make sure about that. Thanks.

 

move the power steering reservoir and you may be able to.

 

can be done without moving anything, just take the nut off and find a thin enough wrench to pry the pulley off. Might have to push the resovoir over a little, but there's room to loosen it without any problem.
