Powerhouse Press: Hennessey’s Dodge Challenger SRT Demon Packs 1,700HP Punch

Surpasses Rimac Nevera’s Quarter Mile Record in Record Time

Hennessey Performance Engineering is set to unveil a fresh branch, dubbed Hennessey Special Operations (HSO), and their inaugural undertaking will be the construction of a powerful 1,700-horsepower Dodge Challenger SRT Demon 170 package. The first vehicle to undergo this transformation will be John Hennessey’s own Demon 170, showcasing the capability of this thrilling upgrade.

The new release from Hennessey, the Demon 1700 Twin Turbo, is a highly limited edition with only 12 units available for purchase. Starting at a price of $200,000, this high-performance vehicle does not include the cost of the donor car. Unlike previous Hennessey models that simply enhance the supercharger, the Demon 1700 Twin Turbo takes a different approach. The original 1,025-hp engine is removed and carefully preserved while an exact replica is installed, along with detailed modifications to the transmission. This upgrade sees the addition of two Precision 7576 turbos, generating a whopping 1,700 horsepower when fueled by E85. According to Hennessey, this power will result in an impressive quarter-mile time of just 7.9 seconds at a speed of 175 mph. In comparison, the NHRA-certified stock Demon 170 takes a full second longer at 8.91 seconds and tops out at 151.17 mph. Even more impressive, the Demon 1700 Twin Turbo beats the Rimac Nevera’s quarter-mile sprint time of 8.25 seconds.


According to recent reports, the Demon 170’s 6.2-liter supercharged Hellephant C170 engine, which is also offered as a crate engine, has the potential for expansion. Hennessey has confirmed that the blueprinted engine will have an undisclosed displacement, but will feature enhanced internals, exclusive alloys, and advanced cooling systems inspired by motorsports technology.

HSO is the latest branch of John Hennessey’s company, joining its existing arms: HPE, known for creating impressive thousand-horsepower builds, and Hennessey Special Vehicles, which produces the renowned Venom F5 and its various iterations.

The establishment of the HSO department is making a grand entrance, however, it is important to note that new model unveilings will not be happening frequently. Merely 15-20 vehicles will be commissioned by HSO annually and interested customers must submit an application to have their cars modified by the carefully chosen group of technicians and constructors.

The automobiles they produce are unique with minimal availability and tremendous power.

Founder and CEO, John Hennessey, stated that “Demand for our powerful vehicles over the past several years has been so strong that we had to shift from being a high-volume tuning company to more of a factory with assembly lines and all of the logistics that go with delivering over 500 vehicles per year.” This statement highlights the immense success and popularity of our vehicles, which has necessitated a change in our approach to production.In order to keep up with the high demand, we have transformed into a factory-like operation, complete with assembly lines and all the necessary logistics. This shift has allowed us to deliver over 500 vehicles annually, a significant increase from our previous production levels. As a result, we have become more efficient and streamlined in our processes, ensuring that our customers receive their powerful vehicles in a timely manner.This transition from a tuning company to a factory has been a strategic move for us. It not only enables us to meet the demands of our customers, but also allows us to maintain the quality and precision that our brand is known for. We take great pride in delivering top-of-the-line vehicles, and this shift has only strengthened our commitment to excellence.The success of our powerful vehicles is a testament to the hard work and dedication of our team.

The absence of these extreme and powerful builds, which have been the trademark of the brand’s reputation, created a potential for HSO to cater to a particular niche in the market. As such, HSO is determined to step in and fulfill this demand.

Hennessey is pleased to reveal the establishment of a fresh division in our company, enabling us to manufacture high-performance vehicles in limited quantities. As stated by Hennessey himself, “We are happy to announce that we’ve created a new division within the company that allows us to build mega-powerful vehicles in small production runs.” This new development has allowed us to take our latest Dodge Demon 170 model, remove the blower, install a pair of turbos, and significantly boost its power from 1,025 to an impressive 1,700 horsepower. This has been a long-awaited project for our team, and we are delighted to finally make it a reality.

The first step to apply for the HSO program is to visit their designated website, although there has been no announcement regarding the expected delivery date. According to Hennessey, the initial vehicle to undergo the conversion will be John’s personal car and this process will take place “in the coming months.”

According to Hennessey, the production process will begin with customer cars and then move on to other products. However, all of these items will be manufactured in limited quantities. In an interview with CarBuzz, Hennessey revealed that there will also be “some one-off builds for clients who possess the necessary donor vehicle and financial means for an exceptional project.”

We eagerly anticipate Hennessey’s potential with an open budget and a willing purchaser.
