I'm intending on using a roots style blower for my build, and was going to purchase the Carb Legal XCharger kit until it appears ExplorerExpress went under. That's just what I've assumed from trying their 3 lines (disconnected/led to telephone surveys). Anybody know of another carb legal positive displacement kit for the 4.0? Unfortunately moddbox doesn't fit the bill. I'd imagine there's nothing out there, and as great as vortech can be, I'd like to go PD if possible. Thanks, any help is appreciated.
