VF Supercharger Installed - Upper radiator hose
ESS TS2 has a similar problem with the supercharger drive pulley. Their solution was a new upper radiator hose that is essentially backwards and a bracket that keeps the hose away from the pulley.... It all came with the kit.
I would look into BP suggestion first. I never had to pull the radiator or the expansion tank to install my SC but every kit is different.
A pic of the bracket. Hard to see in a phone but if you zoom in to the power steering reservoir, you’ll see it attached at the bottom
