One of the local speed shops has a slightly used F3 Procharger for sale. I read through the Empire thread about running an F1 on a Power Stroke. It mentioned an F3 but never got in depth on it. I am by far no expert on 6.4's I was just wondering if this supercharger would be beneficial on a stock fuel factory compound truck ? Would it be similar to running a big atmosphere in front of the stock turbos with a better low end? Or would it eat up any power it made like the F1.
