Hey everyone, So the supercharger is on the car, the pulley plate is also on the car, the supercharger has a nice pulley, the assembly is almost completed. My questions to everyone is - why not use the OEM BMW INA bearings? They have a diameter that is slightly bigger (2.75" vs the 2.5" claimed by others here), and they are probably as sturdy as a bearing can be, or am I missing something major? Thanks! Artem |
