I have a used 3.1 Magna charger Radix Keyed Supercharger Pulley.
I was able to make 9lbs. of Boost with it.
I also have an ECS Roots Style Tensioner.
This Tensioner stopped my belt from jumping under load.
It also increased the boost by helping to eliminate belt slip.
It has about 8,000 miles of use on them.
I'm asking for $250 for both plus shipping.
