It is time to pay another visit to the forced induction wizards at Fathouse Fabrications. They managed to squeeze over 200 extra wheel horsepower of a brand new 2020 Shelby GT500 by installing their 900R performance package. While the stock modern Mustang pushes 679whp, after the 900R package was installed and the Stallion was tuned on E85, it showed 897 wheel horsepower on the dyno. You will also see a 60-130mph acceleration at the end of the video. So turn up the volume and enjoy the sound of this rowdy 2020 Shelby GT500.
