Kompressor/ Supercharger Pulley kit suitable for SLR models only:
The new 85mm Supercharger pulley is smaller than the standard Mercedes pulley and allows for the same amount of boost gain as the larger 172mm crankshaft pulley.
The pulley is a complete replacement of the original SLR pulley, and is supplied fully fitted with a new Nachi bearing as used in the original pulley by Mercedes. You simply use your original supercharger belt.
The typical performance gain is up to 42bhp and 50lb/ft torque. Boost increases to 13 PSI.
