Just got the NEW ///RRM Crank pulley installed!
I think he meant what are the benefits of upgrading the stock pulley to the RRM lightened pulley.
The RRM pulley weighs about 1/3 the stock pulley. You know how you lose about 15% of your engine power at the wheels, well that power is spent in spinning the pulleys and what not. The heavier the object to turn, the more energy is needed to turn it. Reduce the mass, reduce the amount of power needed. So by using RRMs pulley, you reduce the spinning mass, thereby freeing up more power and allow that power to make it to the wheels.
