I "cleaned up" certain data out of this, but is the "exploding Tcase" datalog.

It blew up at 22:36, watch the speed jump as the tires spin. 4650 RPM shifting.

Launched at 3200 RPM, 30 PSIG boost:

Pat have you seen the atlas transfer cases? ORU converted a 2wd truck with one of these, They're supposed to be bullet proof.

Thanks!

That is a divorced Tcase for setups like SFA's.

I'm just going to drop another stocker in.

If that breaks too, then I will have to think of options like the Atlas.

Ya I noticed that and wasn't sure if it was something that you could make work and was worth it.:)
