You already have 9psi pulley on serp side and a 3.47 pulley yeah?
If so, all you need is the 3 inch one since the 2.85 will overspin it xD

I replaced the stock 8psi pulley with the 9psi on the serpentine side. I haven't replaced any others.

Technically just the 9psi pulley alone slightly overspins the head unit unless you upgrade bearings.
