How long will a supercharger last?
Depends on the how hard the vehicle is driven. 99% of all
factory supercharged vehicles are using eaton roots type
superchargers/Positive displacement. Eaton superchargers web site
states, "they are designed to last the life of the vehicle". The
only centrifugal (paxton,vortech,procharger,rotex type) factory
superchargered vehicles (that I know of) are the previous keonisegg
and the Alpina B7Centrifical superchargers. Eaton states that the
oil in the gear case is designed for the life of the
supercharger/doesn't need changing, but say if they are frequently
raced 20k miles cahanges are ok. I know centrifugal types have
problems with drive belt life, especially when pushing higher
boost. Prochargers recommend 6k mile oil changes for thier self
containted oiled superchargers.
