Supercharger bearings

1848 Views 6 Replies 5 Participants Last post by  Himmelkat
when installing a fixed 2.85 upper how long do the bearings last before they start to get noisy and need to be replaced with high speed bearings? From what I've read people have had problems with the oem bearings and also others not have any issues at all. Im going to be taking the supercharger off anyways so I figured id just upgrade the bearings now so I don't have to deal with them in the future or should I just run it and see?

It's gonna be hit or miss, one thing that will help is if you use a decoupling upper like factory.
