I bought my raptor in Oct of 18 and it came with everything it currently has on it. Including a phase 1 roush supercharger. I love the power it has but feel like there could be more. In a couple of weeks I have a custom dyno tune scheduled with my local shop. Seeing as it's the phase 1 I'm not expecting huge numbers but I also noticed that the only difference between the phase 1 and phase 2 is the pulley. And I know they use to offer an upgrade kit for phase 1 to phase 2. But I cannot find it now available anywhere. Does anyone know of a site that sells it? Or know where I can buy the 75 mm pulley?
