Custom Crank Pulley - Procharger

[S.A. GOAT]

Does anyone have a larger diameter crank pulley for their ATI charger? I've got a D1SC with the smallest pulley procharger recommends - 3.4 inch. I can only manage 10 psi, but would like 15 or so. My motor is forged, nice fuel system, and compression is lower, so she's ready to be pushed.

Or, has anyone heard of using a blower pulley smaller than 3.4 inches?

You can purchase a crank pulley and the use a larger blower pulley for better belt wrap.
