Da bekommt man doch gleich Pipi in den Augen, Hennessey Performance stellet den SRT600 vor, welcher auf dem Challenger SRT8 basiert. Neben ihm sind auch noch andere Schmankerl für den 6.1L HEMI V8 von Chrysler veröffentlicht worden, welche die Leistung von 575 PS – bis hin zu Kompressor und Turbo Umbauten, welche dann eine Leistung von 725 PS erzielen soll. Besonders sticht dabei natürlich der SRT600 heraus, welcher auf der viertel Meile jetzt eine Zeit von 11,9 Sekunden bei 121 mph erzielte. Neben dem Leistungsupgrade wurden Veränderungen an Fahrwerk und den Bremsen vorgenommen, ebenso spezielle Drag Racing Reifen montiert. Der SRT600, welches auch auf den Namen HPE600 Turbo Paket hört, wird insgesamt 74.950 Dollar betragen (ein SRT8 sollte allerdings vorhanden sein).

PRESS RELEASE

620 HP Hennessey Challenger Hits the Streets with Eleven Second Quarter Mile Force

SEALY, Texas – Hennessey Performance Engineering (HPE) is well known for its ability to take fast Mopars-such as the Dodge Viper-and make them go faster. The all-new Challenger SRT8 has just hit the streets with its 6.1L Hemi V-8 and in traditional fashion HPE already has performance upgrade packages available. Despite packing 425 hp, HPE knew that many Dodge Challenger SRT8 buyers would want improved power and performance to make their new hot rods even hotter. Now Challenger owners can have Viper and ZR1-like power in the form of 620 hp and 650 lb-ft of torque.

HPE offers numerous packages for the new Challenger including naturally-aspirated versions with 500, 530 and 575 horsepower or forced induction applications (either turbocharged or supercharged) producing 600 to 725 horsepower. The most popular package is expected to be the Hennessey HPE600 SC that is now available directly from HPE as well as from its growing dealer network, including Ringgold Dodge of Ringgold, GA.

While HPE set out to improve the all-new Challengers’ straight line acceleration, the company also developed track tested upgrades to help improve the car’s handling and braking. “The Challenger does a lot of things very well and the factory SRT8 is a great car to start with,” said company founder, John Hennessey. “Unfortunately, it’s a big car weighing over 4,000 lbs. So, while we can’t remove 800 lbs from the car, we can add another 195 hp.”

In early testing a Hennessey Challenger HPE600 Turbo recorded a quarter mile time of 11.9-seconds @ 121 mph on optional Nitto Drag Radial tires with a conservative launch. In addition, the HPE600 also spent time on the Carolina Motorsports Park road course where HPE’s suspension upgrades (including KW adjustable coil-over shocks/springs, larger anti-roll bars, and unique bushings) were track tuned. With the significant increase in power and handling, HPE also has available for the Challenger a set of vehicle specific StopTech brakes replete with lightweight rotors.
