well, at Nopi this past weekend I found out the lifespan of the pulley clutch, the hard way. I spent a while diagnosing the problem until it was very evident. 35,000 miles(on kit) for those of you who are wondering. I always left the switch at low, so you can greatly expand the life of the charger if you leave it off for normal driving.

Thanks for the heads up, just do what I did pin the pulley and no more clutch problems.
Plus now you will have boost all the time with no lag.
