Last week we fixed a host of previous installation and software faults on this gorgeous widebody facelifted C63 with a Magnusson Carb SC kit. She came in making nearly N/A C63 power and was shifting poorly. Most of this was due to the blower making a measly 2.5psi due to the belt routing spinning the blower counter clockwise (!). Also the belt routing completely bypassed the alternator. The SC bypass was being held open as well from a compromised vacuum line. 8.5psi later and a large amount of sorting she’s back on the road with a huge hp gain and drivability back. See video for one of the best sounding V8s ever made!
