Magnuson supercharger

Just wondering, what kind of maintenance are required.
I had it on my 16 Pro for 2.5 years/20k and have not done a thing to it.

 

Nothing for about 100k mi from what I'm told. The oil system is self contained so no need to change it frequently. The Magnuson rep tole me if it ain't making any weird noises leave it alone. You may have to have the drive pulley and bearings rebuilt if it's making noises other than sounding like a vacuum when its spooling up.

 

Thx, was wondering how long the belt would last as well.

 

Like any other serpentine belt when you get more than 12 cracks per inch in the grooves or if it starts squeeling then change it and keep the old one as a spare.
