An Extra 200 HP Goes a Long Way

Hennessey Performance recently took a customer’s 807-horsepower Dodge Challenger SRT^® Jailbreak to 1,000 HP! In the video below, Hennessey team members Alec and Mike take us for a ride in the modified Jailbreak and you can almost feel the power as you watch, with the loud purr in the background as they walk us through what went into this almost 200-horsepower boost. A final shakedown is important before delivery back to the customer, but we think these guys might have been having a little too much fun … if such a thing is possible. Watch below as this 1,000-horsepower Dodge Challenger SRT Jailbreak takes on the Pennzoil Proving Grounds. Let us know in the comments how you’d customize your Jailbreak!
