Watch Hennessey's Deep Dive On The New Dodge SRT Demon 170

John Hennessey’s pursuit of ultimate American performance continues. John Hennessey, and even more so his eponymous Hennessey Performance, is known for an insatiable desire for and incredible ability to achieve amazing levels of automotive performance, whether it be through upgrading trucks or SUVs, tweaking the performance of America’s favorite performance cars, or by creating an unfathomable hypercar from the ground up. However, with the introduction of its celebratory SRT Demon 170, Dodge and SRT showed off its approach to American performance to the very best of its ability before the industry’s transition to electrification spells the end of muscle cars like this one as we know them. At long last, John Hennessey’s new SRT Demon 170 has been delivered, finished in the iconic Plum Crazy Purple paint color, and that’s just the beginning of what makes it special. It’s the most powerful SRT creation yet at 1,035 horsepower with 925 lb/ft of torque, and it broke records with a 1.66-second 0-60 time, all while being a supercharged V8-powered rear-wheel drive vehicle, unlike the electric vehicles that have been putting up similar acceleration times. As the swan song and grand finale of supercharged V8 SRT muscle cars, Hennessey is excited to put the new Dodge SRT Demon 170 to the test on its Pennzoil Proving Grounds in its Sealy, Texas headquarters facility. However, with the car in stunning delivery condition, what needs to come first is a close look at everything that makes the car what it is. With the incredible SRT muscle car ending and the Demon 170 being the finale, Hennessey celebrates one of the greatest achievements in American automotive performance yet.

Watch Hennessey Race The MAMMOTH 1000 TRX Against The For...

Hennessey matches up two performance pickup legends. As the automotive world transitions to electrification and perfects its approach to combustion engineering, electric and gasoline-powered performance vehicles make for interesting matchups. In the pickup truck world, two of the best in their respective realms are the all-electric Ford F-150 Lightning, and the Ram TRX equipped with Hennessey’s MAMMOTH 1000 upgrade package. With Hennessey’s upgrade package, the Ram TRX truck’s power is increased to an incredible 1,000 horsepower from a supercharged V8 engine. However, with its electric power, the Ford F-150 Lightning quietly delivers instant torque for a futuristically powerful drive when the accelerator is pressed to the floor. Hennessey put the two together to duke it out in a drag race at its Pennzoil Proving Grounds at its Sealy, Texas headquarters to see which would reign supreme. In the first run, despite being closely matched at the beginning, the 1,000 horsepower Hennessey masterpiece came out in front. A rolling race yielded similar results, with the F-150 Lightning delivering incredibly impressive performance, with the MAMMOTH 1000 TRX eventually pulling out ahead to finish the race. While both electric and gasoline-powered performance trucks are impressive, Hennessey’s engineering expertise managed to come out ahead of the Ford F-150 Lightning’s futuristic approach.

Hennessey GT500 vs Dodge Durango SRT Hellcat

V8 + Boost = Excitement The roar of superchargers can be heard in downtown Houston. That's because once John Hennessey and his team get their hands under your hood, brutal power will soon appear. On Monday Dodge announced that limiting the production of the Durango Hellcat was a mistake. The 2,000 reservations evaporated within minutes, so they told the plant to keep building them. We're happy because Hennessey has proven the ability to offer 1,000 horsepower at all wheels in a reliable (and tame) daily driver. This is done without even touching the camshaft because that is the realistic limit of the Hemi's bottom end. To see it in action, a GT 500 Mustang was used as the control at the Pennzoil proving grounds. This is another potent platform they can take to 1,000 horsepower should you have a need for speed, so click the button to see what Hennessey can do to your daily driver! Learn More

Hennessey Hellcat vs Demon

2018 Dodge SRT Demon vs. Hennessey HPE900 Hellcat Charger

Every automaker is on an electric push while Dodge has stuffed their supercharged Hemi into the Jeep Wrangler and the Ram TRX. To see how capable it truly is, let's watch a 2018 Dodge SRT Demon vs a new Hennessey HPE900 Hellcat Charger. For a quick refresher, the Demon was the most powerful muscle car in recent history. When the fuel tank sensed race fuel, it unlocked 840 horsepower and 770 lb-ft of torque. While this package was not offered on the 4-door Charger, they share the same architecture. While John Hennessey and his team have offered 1,000 horsepower examples for a decade, one lucky customer chose the HPE900 kit because it isn't as thirsty. Removing the upper and lower supercharger pulleys, their master technicians port the intake and fabricate an all-new stainless exhaust. Without removing the blower, heads, or touching the cam, the car receives a 200-mile shakedown along with a street-tune for the highest octane you can buy at the pump. This results in having 912 horsepower and 873 lb-ft of torque without having to spend big bucks on race fuel. Should the customer ever want to reach 1,000 horsepower, most of the hard work is already done. Tell us which car you would choose in the comments below and stay with us for all your Hennessey news.

Dodge Demon Feature

Hennessey 'Sets the Dodge Demon Free'

When Dodge first announced the new Challenger SRT Demon, one of their main talking points was that the car had been banned by the NHRA. While this is an impressive feat, it's an unfortunate turn of events for those that wanted to run a Demon at NHRA's 1/4 drag strips.Thankfully, there's Hennessey Performance.In a July 18, 2017 letter to Tim Kuniskis, Head of Passenger Car Brands at FCA US LLC, John Hennessey assured the company that new Demon owners will have a place to run their cars to their full potential: Hennessey's own Lonestar Motorsports Park 1/4 mile dragstrip. Hennessey's only requirement is that Demons owners will attend one day of drag racing school with their Demon so that they can become "familiar with burnouts, setting tire pressures and safley operating their vehicles in a dragstrip environment."So, those looking to run quarter-miles in 9.65 @ 140 mph with their Demon will be able to find solace in Hennessey Performance.
