600+ Rear Wheel SOHO A2A 370Z On Pump!

If you leave the filter off and run the 8lb pulley, you preserve the longevity of the supercharger by not spinning it faster (i.e. 9lb pulley) at the risk of engine damage from debris.

If you put a filter on and run the 9lb pulley, you save the engine from the debris, but run the risk of quicker degradation of the Supercharger due to the faster speed.

Per Vortech's impeller speed calculator. You can still use it even though it says "cog teeth" since it's just looking for a ratio. https://vortechsuperchargers.com/pag...eed-calculator



The Si version of the V3 is rated to 52k RPM

The Sci version of the V3 is rated at 53k RPM
