Video is 2 years old, but haven't seen much of Nelson Performance lately. Just a crazy setup, with TWIN gt4088 turbos, on a 3.6l motor.

Edit: their current setup is supposedly 1600awhp, and their new setup should be 1900awhp..dont quote me on it, just what I have seen in a couple forums. They're switching to a single gt55 on a 4.5L motor (6g75 I think I remember reading). They keep all their info kinda secret, which sucks.
