I found a thread on wrist twisters about the idea of putting a turbo kit on a 919. Apparently there were a couple of guys in Colorado making turbo kits for about 2400.00. The thread has gone idle, though, since 2009. Has anyone tried a turbo kit on a 919, or know of someone who has? How did it go in the longer term? I definately find the potential "sleeper" effect attractive.
