With the Vorcrap *cough*, Vortech unit for the Ford Contour, boost isnt seen until nearly 5,000 rpms and doesnt reach max boost redline. It provides only about a 45 ft-lb increase in torque. Its nothing but a dyno queen unit. Not to mention, 12 psi is about the max it makes since the pulley can only be made so small.

and btw, superchargers should have a bypass valve regardless of whether its intercooled or not.
