Hit the Dyno: Hennessey Performance Hellcat


This is the Hennessey Charger SRT Hellcat: finely tuned. This ride cranks out 805 horsepower thanks to some tweaks done by John Hennessey and his team.  Check out what makes the HPE800 Charger Hellcat tick:

  • new ECU with upgraded tuning software
  • less-restrictive air filter
  • upgraded lower pulley to increase boost by 1-2 psi
  • port-matched throttle body

If the HPE800 doesn’t do it for you, upgrade to the HPE850. Either way, you’re feeling the power.
