Dead stock 8 3/4" with a used 3.23 gear (742 case). Can't blame it for not holding up!

TB release triggers the boost ramp to start. I had it set on this pass to go from 8psi to 20psi in 0.7s.

Sprag could definitely be hurt, that's why I didn't try to fix it at the track. I had a buddy coming sat. morning that could have brought a gear, but I didn't want to chance the trans.
