I measured a couple of the pulleys that I could, the others I can't do while they're still on the car, at least not with a tape measure. Also sorry for not knowing the exact names of the pulleys, I'm still learning lol.
Serpentine side:
Top left (the one next to the main pulley that spins the supercharger belt): 2.875"
Top right (the one that spins the supercharger belt): 2.875"
Supercharger side:
Supercharger pulley (the one on the supercharge its self): 3.25"
The rest I either need to take off the car or maybe a caliper would do it
