You also have to take into account the fact that a turbocharger does not require any power to produce boost like a supercharger does. If an SRT engine were to be turbo'd with the same pressure as the supercharger produces, without having to expend the kind of energy turning it, it would produce a whole lot more power, guaranteed.
Half the boost, without the power loss to produce the boost equals pretty close performance.
You also have to factor in the different gear ratios of the limiteds vs the srts. Although slight, the better ratio will always equal slightly better performance in the acceleration race.
