Blown mud truck

This video was taken while the truck was still under construction440 with 671 blower, dynoed 680 horse 6600 RPM. We decided to test out my transmission, the first run I think I accidently bumped it to neutral, second run was clean all the way through 3rd gear. Good thing I dont plan to shift in the mud anyway, its just nice to know things are working properly I need to upgrade to 70 shafts in the front before I lock it Heres a couple links to the videos of this in the mud:
