That thing was way done, brother, a long time ago. It's carbed, so there's no fuel management, besides jetting and dyno tuning. Turbo'ing a carbed bike is a challenge, but once you know what's going on, it's pretty easy, and much better than a EFI turbo setup. There were electronics on it, for the shot delay (wet nitrous setup) and ignition timing, but that was minor. The wet-shot nitrous was triggered from a mechanical switch that let go when you hit WOT. You could be "mostly pinned" and be okay, but when you laid into it, you got some turbo-nitrous fury... :o 242 lbs, with a full 1 gal fuel cell. 150+ hp. Another finished pic on Wednesday. <thumbsup>
