Meet the World’s Most Powerful 2018 Demon

Modified 2018 Dodge Challenger SRT Demon makes more than 1,000 wheel horsepower on dyno.

The 2018 Dodge Challenger SRT Demon offers 840 horsepower and 770 lb-ft of torque in stock form, but this supercharged Mopar muscle car has been modified by the crew at Forza Tuning and Performance. In this video from the YouTuber Michael Berenis, this Forza-tuned SRT Challenger works out on the dyno and it turns in some impressive numbers – setting a world record for the most powerful new Demon.

Forza Stage 4

The gorgeous Go Mango 2018 Dodge Challenger SRT Demon in this video has been modified by Forza Tuning and Performance with the Stage 4 and Stage 4R packages. Unfortunately, we don’t know exactly what those package entail, but we know that the car in the video above is running on 20 pounds of boost. That is well above the stock boost levels, so this Challenger likely has a smaller upper pulley and perhaps a new lower pulley, but we don’t know what else has been added to hit these numbers.

On their website, Forza states that their Stage 4 package delivers 1,100 horsepower on 93-octane pump and 1,150 horsepower on race gas while the Stage 4R package offers 1,200 horsepower on race gas. Those are not wheel-rated numbers, so to find out how much power this package makes at the wheels, Forza hit the Mustang Dyno at The Tuning School in Odessa.

The results are impressive. In fact, they are record-setting.

Dyno Demon 

In the video above, the supercharged Challenger makes a handful of blasts on the dyno and all of them are impressive. At first, the Demon is tested with the Forza Stage 4 package and 93 octane pump gas, and it lays down figures of 868 horsepower and 794 lb-ft of torque at the wheels. Considering that this Demon made 720 horsepower and 701 lb-ft of torque at the wheels in stock form, the increases of about 150 horsepower and almost 100 lb-ft of torque is solid.

When the VP Fuels MS109 goes into the new Challenger, that is when things really get interesting.

On the first run with race gas with the Stage 4 package, the blown Dodge makes 911 horsepower and 847 lb-ft of torque at the rear wheels. After some tuning adjustments, horsepower levels climbed to 926 hp while torque remained in the 846 range. Those numbers are recorded about 11 dyno runs on a 93-degree day in Florida, so the air was hot and the engine was hot, but the numbers were still very good.

Finally, after some adjustments that we believe come as part of the 4R package, this Go Mango Demon makes one more rip on the dyno and the team hits the desired record – over 1,000 wheel horsepower. To be exact, this Challenger maxed out at 1,038 horsepower and 952 lb-ft of torque at the rear wheels, so the final tuning adjustment made a massive difference.

Figure that with a conservative drivetrain loss factor of 18%, this Demon is making somewhere in the area of 1,265 horsepower and 1,161 lb-ft of torque. In any case, with 1,038 wheel horsepower, this 2018 Dodge Challenger SRT Demon is the most powerful of its kind.

"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.

"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.

"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.

"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.

"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.

"Being based on Detroit," says Rall, "I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit's Woodward Avenue with the best muscle car crowd in the world.
