Removed the stock Eaton supercharger from my 2005 Cooper S at 68,000 miles to make way for the Sprintex supercharger upgrade. The Sprintex past the test, so I'm keepin it Comes with everything seen here Craven Speed 15% pulley installed New water pump installed just 2 weeks prior to the removal of supercharger (Sprintex uses an electric water pump) I'll sell the complete rig as seen here for $800.
