Not only do superchargers make a fast car even faster, their piercing whine is an unmistakable soundtrack that never gets old. Dodge is able to make 707 hp in their SRT Hellcat Challenger and Charger by using a 2.4-liter supercharger, but there is always room for improvement. Last week we showed you what John Hennessey is able to do with his new 2.9-liter blowers in the HPE 1000 CTS-V and HPE 650 Denali, and it’s easy to see how more boost translates into more power. It seems that bigger is better when it comes to forced induction, so watch what happens when a larger supercharger is tested on a new Hellcat Charger sedan by clicking the play button on the video below. Congrats to her and her crew for on their achievements. And if you're wondering what her car's packing, here's the list from the video's description:
  • Metco upper pulley (18psi)
  • ATI Lower Pulley
  • Catless mid-pipes
  • 3.09 Rear gear swap
  • Driveshaft Shop driveshaft
  • Diablosport CMR tune by HHP and HEMITUNER Performance
  • 902hp/866tq
