    • Mustang dynos always read low? Really? AMS Performance shows how to do dyno manipulation on their Mustang Dyno

      Dyno numbers. Oh how we all love dyno numbers. Used for bragging rights on automotive forums around the world and everyone wants those big numbers. Those big numbers should come with hard work, sweat, and, well, a bit of money. But some people mess up using dynographs as a comparison tool for the rest of us by inflating their numbers. That can't happen you say? Well, recently a '1300+' wheel horsepower M6 was a prime example of dyno manipulation and AMS essentially shows how it is done to perfection on their Mustang dyno in the video below.


      For comedic value AMS decided to use a Nissan Sentra. They set a weak baseline on the Mustang. Then a set of "upgrades" is claimed and some audio is changed and suddenly the Mustang reads out 410 at the wheels and 360 pound-feet of torque at the wheels. For the next run AMS states the motor is built, more boost, and they use an F1 or Indy soundtrack (nice touch guys!) while filming the stock engine bay.

      The result? 660 wheel horsepower. The exact same car set very different results simply by manipulating the software. From 160 wheel to 660 wheel by pressing a few buttons? Yep.

      The drag strip can not lie like this. It can be leveraged with good weather in certain locations, sure, but it won't blatantly lie. For those who say Mustang dynos always read low, that is not always the case depending on how the dyno is setup. Take those dyno numbers with a grain of salt.
