Yeah been looking at the Jackson racing, but the better option is the Comptech Charger (CT engineering)
It using the same supercharger unit but the nose bracket that has the output shaft is extended giving better support than on the Jackson unit which is prone to snapping.
The tensioner is a far better design on the CT using a twin roller system. CT have redesigned the axel supports to offer more support.
The CT kit is a direct fitment. No cutting or modifying of other parts unlike the Jackson that requires you to trim the thermostat housing and bend an aircon pipe. The CT kit does come with a spacer for the aircon line to extend it which is a nice addition but it does mean you need to break the pipes so a re-gas is required.
The CT kit runs at 10PSI as well wheras the Jackson runs at 9PSI with similar mods.
The actual chargers are the same design made by Magnusson and have proven very reliable but its the little extra bits that make the difference but its is a good proven system.
It also comes with a pretty cool carbon cover:
