I'm running the '9 psi' pulley and at 7500 engine RPM the impeller is spinning at just a hair over 56000. Do you know the diameter of your input pulley?
Their impeller is balanced to within .006g/inch at 60,000 RPM. So it will obviously be spinning faster but I don't think it will be enough to cause concern. Im going to start with a new combination and go from there. The 9 psi pulley, 2.85" supercharger pulley, and 3.47" jackshaft pulley. We might be bumping my redline up a little as well.
