I ran a Vortech V7 YSi centrifugal on my 480" FE for a while, ran Drag Week with it in 2007 too. The engine made 1030 HP on 17 psi boost, but the ribbed belt wouldn't hold the power required so in order to get past 11 pounds of boost I went to a toothed belt. Biggest issue I had was ducting air to the blower inlet in my Mustang, where the blower was positioned backed the inlet up towards the shock tower, so I had to use an elbow there and that really hurt performance, probably over 100 HP. I ended up cutting a hole through the inner fenderwell and putting a screen there, plus a block off plate. I removed the elbow and the block off plate to let air in through the inner fender at the track, and kept them in place on the street. I also ran a carb, which was a special from CSU Carbs just for blower applications. It worked better than any other carb I tried, but was extremely sensitive to jetting changes. I am repurposing that engine for my 68 Shelby, and will be going EFI to eliminate the carb problems.
