Now that the new 2020 Shelby GT500 is finally here it's time to start modding. Since the new GT500 is supercharged like the previous Shelby's going to a smaller supercharger pulley yields great gains in horsepower and torque. The stock pulley on the new Shelby GT500 measures 3.08" so going to a smaller pulley increases rpms spinning the supercharger at a higher rpm creating the increased boost. A custom tune is typically required when going to a smaller pulley so make sure to check out all of the custom tuning options we offer here at Lethal Performance's Tune Shop.
