I have some experience with this . . . You're moving into the serious mod territory. You will definitely need to install a high volume (SL55 type) fuel pump, an unrestricted fuel filter and a separate adjustable fuel pressure regulator. The stock SRT6 fuel pump will NOT provide enough fuel for the demands created by the 61.9mm supercharger pulley. You're generating more boost and without feeding more fuel you risk serious damage to your engine.
