The 5th Generation Superchargers incorporate an innovative rotor coating that allows for tighter internal clearances compared to previous applications. These tighter clearances allow for increased supercharger efficiency and performance, resulting in improved horsepower and torque at lower engine RPMs.
SUPERIOR Gen V SUPERCHARGER
The heart of the supercharger is a new "high twist" rotor design developed by GM Powertrain, in conjunction with Eaton Corporation. This design is more efficient and provides more airflow than any other OEM helical roots-type supercharger. While the revised helical rotors are new.......
I have heard that the new coating is teflon.
