    In testing you will not gain the increase in RPM or boost like you are thinking. It is minimal at best. The SC, if you talk to Eaton, will only produce so much and that is it. This is not like the other types where the faster you turn them the more boost you make. You can get your RPMs up through other methods such as tuning, nozzle sizes, and impeller but even then before you go through purchasing and installing a pulley, you will see there is not much of an increase if any.

    If I put a new SC, can I obtained more RPM and boost, if change the pulleys? What else can I make to increase speed.

    Acceleration will be a lot better if you can get your prop dialed in. Top speeds hard to come by
