Yeah, it’s not gonna come out of AWD/4wd under load. The vacuum is simply applied and the interlocking friction will hold the hubs engaged until they finally are allowed to separate. Not good for the hubs. I get great numbers with mine in 4A. Don’t have recent Dragy #s, but the last actual drag strip runs match my Cobb AP data, so easy 12sec @ 108 1/4 mile, 1.8 60ft, etc, etc. 10Spds’ data looks good to me. Especially with trying to shift the hubs under load.
