So, Carl from 928motorsports e-mailed me back with a response to the leak issue.
He told me to use his calculator on 928 website to find out how much I am actually spinning assuming no slip.

The calculator has 3 components:
(1) Size of Crank Pulley Diameter
(2) Size of Blower Pulley Diameter
(3) Internal Blower Setup Ratio for V3
(4) Max Engine RPM

Is the crank pulley the diameter of my ATI crank pulley that I had put in? 5.5"?

Is the blower pulley diameter .. I don't know? Isn't there 3 different pulleys on the supercharger belt? 2 SC pulleys and 1 idler pulley? I changed out one of the stock 3.2" SC pulleys for a 3.0" so would I put 3.0?

Max Engine RPM speed = 7.5k ish?

Anyone can help?


SOHO responded but didnt really answer my question, so Im not even going to post what they said.
