DEMON 1700 Twin turbo

Hennessey®, the Texas-based hypercar manufacturer and high-performance vehicle creator, has released a performance upgrade package for the 2023 Dodge Challenger Demon 170. Hennessey's boost in output for the 6.2-liter HEMI V8-powered engine takes power from the 700+ bhp factory level, to a wild 1,700+ bhp – transforming the performance driving dynamics of the Dodge Challenger Hellcat.

Testing for all Hennessey® Performance models begin at the company’s headquarters in Sealy, Texas. Under the guidance of our Research and Development team, each model line is subjected to hundreds of hours of research and development. This helps guarantee that Hennessey® Performance's 2023 Dodge Challenger Demon 170 performance parts enhance every aspect of the vehicle while retaining complete usability and manufacturer driving modes.

After lab-based evaluation, development moves to Hennessey® Performance’s various on-site dyno bays for live assessment. The final phase of tuning has development models of the Dodge Challenger Hellcat test at the Pennzoil Proving Ground at Hennessey® Performance’s headquarters. This final phase is performed to evaluate the 2023 Dodge Challenger Demon 170 H1700 tune upgrade in the real world. Even after each model line is signed-off, every customer vehicle undergoes its series of quality assurance tests, including a detailed test drive by Hennessey® Performance’s engineers.
