    This video is proof that "there's always someone faster." A Hellcat (that runs mid to low 10s) races a modified 5.0 supercharged Mustang (with 20 lbs. of boost) and the results were not good.

    Besides the Mustang's performance mods, you have to consider that it is a much lighter car than the Challenger.

    An illustration of how weight can affect performance can be found in the October 2018 issue of Motor Trend, where 1/4 mile times were compared between a Jeep Grand Cherokee Trailhawk (707 hp.) and a Mercedes AMG GLC 63 S (503 hp.). Despite a 203 hp. disadvantage, the Mercedes produced an identical ET of 11.7 sec. @116 mph. How? The Jeep weighed almost a half of a ton more (945 lbs- 5,448 to 4,505 lbs.).

    As a side note, there is a 1/4 estimator on line that is fairly accurate. You can play around with weighs and horsepower to see the affect each has on ETs. For example, if you plug the numbers in for the Trailhawk and Mercedes, you get the following:

    Trailhawk- 11.2 sec. @118.4 mph
    Mercedes- 11.8 sec. @112.7 mph

    Yeah...With the Mustang being in the neighborhood of 600 lbs. lighter, I found it strange that he was making reference to seat removal.
