yes it distributes 50/50 power to the front and rear. also to dyno, all you would have to do is drop your transfer case and be good to go to dyno on a 2wd dyno. another thing you can get away with, lets say if you break an axle at the track you can limp home in 3wd mode. another option to look into is a spool, does the same thing, look into TRE's, its good stuff.
