e9 is proud to announce our Auxiliary Drive Cog Pulley Conversion Kit for existing VF Engineering Stage 2 Supercharger kit owners.
Our auxiliary drive cog pulley conversion moves the V9 supercharger out away from the motor, adding an independent and dedicated cogged belt to drive the supercharger eliminating all belt slip. Consistent power is maintained on every shift through the rpm range while enhancing the drivability that supercharger owners have grown to love.
The conversion kit has been engineered to mount with the Fluidampr crank pulley for a number of reasons, notably the reduction of torsional vibration which equates to greater valve train and timing efficiency, plus reduces wear of critical engine components such as main bearings, oil pump and the crankshaft itself. A more efficient engine is a more powerful engine and independent dyno’s have proven gains of 3-15whp from installation of the Fluidampr alone. This is why we opted to fit our Auxiliary Cog Drive Pulley to something that will continue to become more effective as magnitude increases and help reduce parasitic loss.
e9 stands by its products and the products we choose to feature in our kits. Un-compromised quality is what we strive for and this is why all bracketry and pulleys are machined from T6061 aluminum and is either black anodized or black hard anodized respectively. Both stainless steel and high grade tempered hardware is used for all mounting points.

*Heavy duty supercharger bearings are recommended for use with any cog pulley system. Please contact us if you’re unsure what bearings you currently have installed or wish to upgrade*
**Kits were designed for 6500 RPM shift points. Operating above this RPM will shorten bearing life between rebuilds**
