Last winter I had the engine rebuilt and also upgraded from a P1SC to a D1SC. My next step is to upgrade the fuel and maf to handle the additional power. Question is what size pulley should I go to?

Found this calculator:
Procharger Pulley Boost Calculator - Zero2Sixty Motorsports

If correct then my pulley size would need to be 3.85" for 59636 blower rpms (3.7 would max it out at 62054)

Hoping someone with a similar set up can confirm/deny these results.
