Torqueflights that actually explode are caused by having the sprag fail & the front drum free spinning to the point of failure... That typically happens when the drum exceeds 9-10K.. Engine RPM would be less but still likely 6500 rpms.. When doing burnouts I doubt my engine ever sees 5000 rpms...
The burnout that will get ya is holding first gear coming out of the water & the tires hook.... And the trans blows not during the burnout but when you leave the line...
Since there's no water involved in any of my burnouts there's no sudden change in grip so laying the sprag over isn't an issue...
I think you need another glass of milk....
