The gearsets aren't likely to strip at that power level! The mumm brothers are the only case I've heard about it. When you have completely solid mounts and massive final drive components then they might become the weaker links but I'm guessing it was driveline lash/shock that would crack them due to the solid mounts and stiffer components. The motor mounts really protect the components from the heavy, extremely fast rate of loading; even the urethane is flexible enough to provide some protection from this lash.
