MMS Pulley

What gains do you get from installing a MMS pulley on a D1SC Procharger?

Thanks,
Justin

A larger crank pulley will increase boost. 1" larger crank pulley equals .5" smaller SC pulley. It will also reduce the belt slippage because u can run a larger SC pulley and make the same boost.

Ditto, but they are kinda hard to find as MMS is out of business . I think it's worth hunting one down , I have one with no noticable belt slip .

If u want an even larger crank pulley u can get the ATI 8 RIB crank pulley with the ATI Superdamper. Its 7.65" and u can upgrade up to 8.5" crank pulley. We are installing the 8.5" crank pulley as we speak and looking for 11-12psi.
