We have an 04 MCS with the JCW kit. Since I don't need to reduce the SC pulley, is there a benefit to changing to a 2% crank pulley? What are the risks/drawbacks?

Thanks

 

Yes there are beneifits to using a crank pulley. Basically whats happening is that by reducing the rotational mass, your are in turn increasing horsepower and torque. Also another benefit is since your using the 2% crank pulley you will up your boost a bit. So for example if you were using a 15% s/c pulley and then used this 2% crank pulley you would be actually using a 17% s/c pulley. Im not sure if I really explained this right but I gave it a shot.....In regards to the drawbacks, there are some people that say there is, but I dont think anything has been truely documented.
