P1SC to D1SC.... Is it worth sending my P1SC blower back to ATI to upgrade it to a D1SC? Since now i'm building a complete forged bottom end i want to up the boost. Does the D1SC start making boost at the same RPM as the P1SC?

Re: P1SC to D1SC.... I'm not sure the what the map looks like between the two (they never seem to publish that info). I do know that the d1 will make more boost up top with the same pulley. It's also a bit louder.
Re: P1SC to D1SC.... The D1 does produce more CFM and has a higher RPM limit. The CFM is important for larger CID motors and the higher RPM is important for making for boost.
