Not sure if you remember from my 350z build thread, but will refresh this here.
To eliminate the belt slipping, a famous mechanical engineer in USA did the "TimRod Radius Rod", which is basically a stiffener bracket that eliminates the flexing of the supercharger mounting plate. I had this fitted on my car and eliminated any belt slipping on the dyno and afterwards on the road. Here are some photos with the brackets in both variants, DE and RevUp, but also fitted on my car:

Final fitting:

I recommend this to any of the guys going Vortech SC. The Radius Rod will support the SC mounting plate at the far end on the blower side, stopping any mounting plate flex, that will contribute to belt slip. There are lots of threads in the US forums, most of the Vortech guys have this fitted on their cars.
TimRods car is featured on Vortech's site here: http://www.vortechsuperchargers.com/page.php?id=42331 you can see the bracket fitted in the photo with his engine bay. TimRod holds the record for the fastest untouched stock engine with Vortech SC, 10.903 @ 130.30 mph.
I've spoken to him again, after bringing this to UK for a few members in here back in 2013 and I will be importing a few more now.
