In this video, the LMR crew dynos one of the best Mustangs to ever roll off of the assembly line - a 2013 Shelby GT500! This Grabber Blue GT500 is an exceptional example of a low-mile, stock car. We provide info on two different dyno runs: a heat-soaked run and what we call a "hero" run. A "hero" run means the car is brought to operating temperature and then run on the dyno. The supercharger and surrounding components don't have time to heat soak. The result is more power and torque at the rear wheels. However, when you're driving around on the street, the "hero" run doesn't mean squat! That's why we provided a heat soak run to prove that what you see on the Internet is usually always the "hero" run. Enjoy the video!
