SC upgrades available are to get a port job, replaced pulley with a smaller overdrive pulley (the smallest need the snout machined), and replacing the rotor impellers with ones that have more helical twist. There used to be an internal gearing swap to get more rotations per pulley revolution (snakebite kit) but I'm not sure that is still available. A larger throttle body can be added to reduce some restriction going into the SC.
