from rotrex's website the c38 has a 1:7.5 gear ratio with a max impeller speed of 90,000 now we need an accurate measurement of the O.E. pulley.

Edit: also due to the high speed nature of centrifugal superchargers the manufacturers redline is usually set a little lower than it's designed redline to CTA for warranty reasons.
