Trying to compare how much boost it produces at 7200rpm vs the 75mm pulley designed to spin the rotrex to 7800rpm on their base maps. To me it's sounding like the 70mm is the route to go, I do not want to rev anywhere close to 7800. I have a long history with Subaru oil pumps in regards to cavitation.

Why not go with the C38, and use a larger pulley? This will give you future room to upgrade to more power when you eventually want it, without over spinning the C30 SC.
