That's true enough for the engine failures, but the diff failures mentioned above can be directly attributed to 1/4 mile runs. Unless the car hooks up perfectly, there is a fair risk of causing impact damage to the diff,
especially if any wheelhop occurs. I've seen 1st hand (from testing we do) what impacting can cause - the diff may not necessarily granade on the spot, but hang on enough so that it fails later on, when you least expect it... The impact can cause cracks at bottom of the gear teeth, but may not fully break them off. Normal driving will then fatigue the weakened teeth until they eventually fail. Anyway, that's enough OT rambling...
