Does anyone know the crank pulley size??? Outside diameter where the belt sits, I’m trying to figure out what’s the smallest pulley I can run without going over the Superchargers max rpm.

I don't have your answer, but you need to run a larger crank pulley to spin a supercharger faster. The crank will always spin at the same RPM as the engine, so a larger pulley on the crank will make the belt travel farther in the same amount of time. This will make the supercharger pulley spin faster to keep up. I haven't looked at the block on the IS, but make sure there are no protrusions in your way to go larger.

Im not changing the size of the crank pulley im just need to know the size so I can do the math and figure whats the smallest pulley i can run on my C2 procharger.
