Dodge shook the automotive industry when they announced the Dodge SRT Demon’s performance numbers back in April of 2017. The stock Demon’s claim-to-fame was that the 840 horsepower Challenger with the race ECU would blow through the 1/4 mile in an eyebrow raising 9.65 seconds at 140 mph. To add to the list of impressive numbers, the stock Demon launches to 60 mph in a hyper car caliber, 2.3 seconds.


When everyone else in the industry was picking their jaw up off the ground from the Dodge press release, Hennessey Performance immediately went to work on R&D to come up with an upgrade that would shatter the factory Dodge Demon’s performance numbers. Several months later, Hennessey did just that. The Hennessey Performance HPE1000 Dodge Demon ran a 9.14 second 1/4 mile at 152 mph at Lonestar Motorsports Park on May 8, 2018. “The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car’s impressive track times to an industry leading level.” said president and company founder, John Hennessey. “Over the past several months we have worked to develop a low 9 second drag car that our customers can drive to the track, put on an impressive show with blistering 1/4 mile times, and then drive home in complete comfort.”


The HPE1000 upgrade for the Dodge Demon increases the factory 840 horsepower to a tire-shredding 1,035 horsepower and 948 lb-ft torque. That equates to approximately 880 horsepower at the rear wheels after the car’s automatic transmission drivetrain loss. The Hennessey HPE1000 upgrade also shaves the 0-60 mph time to an incomprehensible 1.9 seconds. The HPE1000 upgrade includes a massive 4.5L supercharger system that replaces the factory 2.7L system. The upgrade also includes stainless steel long tube headers, a high-flow air induction system, upgraded throttle body, upgraded fuel pump and fuel injectors, with the company’s custom engine management calibration. All said and done, HPE1000 customers will walk away with a 1 year / 12,000 mile limited warranty from Hennessey Performance.


With production of the Dodge Demon being limited to only 3,000 examples, Hennessey Performance will be offering only 50 units. Orders can be placed directly with Hennessey or through authorized Hennessey Chrysler Dodge Jeep dealers.
