Never the less when the springs are stretched too far and too often they will break.
More and more after market SC pulleys will fail, the dog bone springs and bearings are not as reliable as the OEM ones.
I understand what you are saying, the aftermarket pulley was always very close to the electromagnet, I'm just not sure if it is actually touching the electromagnet or not. Will have to slip belt off and see what is going on. If it is always spinning the S/C I may not have the protection needed if the secondary (intercooler) pump were to fail.
