Just found some info on my supercharger. Guess it is really a NOVI-GSS.
The GSS (it's full name is Novi-GSS) came after the SN2000. It was a limited production run, produced as a sort of 'swan-song' for the old ball-drive superchargers. It was the culmination of all the material/design improvements that went into the SN superchargers through each iteration. The name itself is derived from two sources: Novi is from Novi, Michigan and the Novi Indy race cars campaigned by the Granatelli family (then owners of Paxton Superchargers) in the 60's, and GSS stands for Granatelli Signature Series.
Still no idea on boost levels.
