It's not a kit. It is an Eaton Supercharger. I don't like centrifugals. It should be doing between 6 - 15 lbs boost, unless I use a smaller pulley. My primary concern, is what else do I need? Do I have to modify my fuel system? And do I have to make any changes to ignition (new plugs with different heat range?, different timing, etc)? Anyone have any ideas? Anyone here added a supercharger or turbo before?
