My understanding is if the "dry hop" happens to be not-so-dry & You hit it, if the tires spin unloaded for a split second then hook, the stator sprag goes from freewheeling to locked in the juice wheel...like neutral dropping it..it may not explode, but could be damaged & just seize, and the converter is junk.
Also, depending on the condition of the surface (& I'm no Pro Drag Racer here), some have told Me the dry-hop messes up the surface of the slick. They state the best traction is rolling out & backing of before they can "bite", and the first "bite" is the best, a dry-hop wastes it. You Pro's here can chime in & correct Me (or argue, :p) if You have a different experience/opinion.
