    Thumbs up Tasking the SN Knowledge

    I just took delivery of an SN 92 that is seized. I need any and all info for parts and diagrams for me to open her up and see if I can rebuild her. Looking for only 6 psi out of this, so not interested in impeller upgrades. Thanx in advance.

    The subjects of parts and assembly diagrams has been repeatedly discussed constantly on this forum.

    Use the Search function or browse around - you'll find all the information you need.

    Sorry, I'm kinda new to the centrifugal type of superchareger. Didn't know if thee was a difference between the models of the SN series. Just looking for exact info. Thanx.

    There's no need to apologize. You haven't asked a "bad" or naive question. It's just one that has been asked and answered several times. The search function will probably serve you much better than waiting for someone to compile all the information you're looking for.

    There are a few differences between the different SN superchargers, but ultimately the SN can be grouped into two versions: early SNs and later SNs. The early SNs (the SN60 and SN89) had slightly different internal design with respect to the oil pump/bearings assembly and the flange mounting design when compared to the later SNs (SN92, SN2000, and GSS). The operation of all SNs was the same, and the flow rate and boost was the same for all (except the GSS which came standard with the H.O. impeller); most of the design changes were made for life longevity and reliability.

    Again, all of these topics (and the differences between the SNs) have been discussed here on the forum.
