Hennessey isn’t just about creating uber-sexy vehicles like the Venom GT. In fact, a lot of their projects entail tuning up existing models and then slapping on an HPE title coupled with the appropriate horsepower number. The latest vehicle to be blessed with the alphanumeric title is the 2009-2011 Dodge Ram and its new HPE500 designation. >
The Ram HPE500 is powered by a 5.7L Hemi that has been geeked up with a TVS2300 Supercharger System and an HPE Air Induction System to help cool the beast down.
This setup can produce 505 HP at 5,400rpm when fueled with 93 Octane. Broken down, it gives the driver 422 HP at the rear wheels with a 20% boost providing the 505 HP at the engine. For comparison’s sake, the Ram SRT10 powered by the Viper’s V10 engine gets 410 HP at the rear wheels and 505 HP at the engine.
