Digging for info - front drum explosion on 727s

^^^^ Dry hop with low band applied in 1st gear? Is that bad? Seems no different than launching the car???

Like you, I have a rmvb with low band apply (Griner valve body). Burnout starts in 1st, immediately to 2nd then 3rd, about 5500 rpm then let off throttle, roll out of box.
