Full Powertrain Spec Sheet For Challenger SRT Demon Revealed, We Compare It To The Hellcat
Pinning a few numbers to the new drag race kingby Jonathan Lopez, on
When Dodge pulled the sheets on the utterly insane Challenger SRT Demon back in April at the 2017 New York International Auto Show, months of speculation finally collided with reality, and the result was one of the most badass factory drag racers ever unleashed. The headline specs on the Demon beg belief, with nearly 850 horsepower and 770 pound-feet of torque sent to the rear axle thanks to a supercharged 6.2-liter V-8. Stuffing the engine is a 2.7-liter supercharger producing 14.5 psi of boost, which prompts at 2.3-second sprint in the 60-mph benchmark. Keep your foot down, and you’ll see the quarter mile blitzed in 9.65 seconds at 140 mph. Insanity. Now, Dodge has a full rundown on hard numbers to document that craziness with the release of the Demon’s powertrain spec sheet.
You can check out the attached press release for all the nitty gritty details, but in the meantime, here are a few highlights. For starters, Dodge says the V-8 engine manages to swallow as much as 173 cubic feet of air during a full-throttle quarter-mile run, which is roughly the same volume as the lung capacity of 816 humans. During a hard launch, the Nitto cheater slicks produce upwards of 1.8 g’s of forward acceleration, enough to lift the nose of the car off the ground for a fronts-up wheelie off the line. There’s plenty of other details as well, so read on if you wanna get nerdy with it as we compare it the “standard” Hellcat.

Demon Vs. Hellcat?
Note: Hellcat on the left, Demon on the right.
When I first heard about the Demon, my initial reaction went something like this – “Wait, they’re building a faster Hellcat?” Truth be told, that’s exactly what’s offered here, so to give you a better handle on what the Demon brings to the party over the “standard” Hellcat, we’ve set up a little comparison.
For starters, the Demon carries a price tag of $84,995, which is a massive $22,500 more than the $62,495 Hellcat. However, for the money, buyers get a ton of extras, including a long list of $1 options that includes a front passenger seat (the Demon comes with just a driver’s seat from the factory), a rear bench (either cloth or leather upholstery), and a carpet kit for the trunk. Dodge is also offering a personalized “Demon Crate” for $1, which throws in a powertrain module for high-octane race fuel, a new air filter, skinny front wheels, a passenger mirror block-off plate, a hydraulic jack, cordless impact wrench, tire pressure gauge, and more.

Speaking of the engine, the Demon’s spec sheet kicks off with a breakdown on the engine upgrades. With a full tank of race fuel (100 octane minimum), peak output is rated at 840 horsepower at 6,300 rpm and 770 pound-feet of torque at 4,500 rpm. Go for the pump gas (91 octane), and output is still a very healthy 808 horsepower at 6,300 rpm and 717 pound-feet of torque at 4,500 rpm. Compared to the Hellcat’s 707 horsepower at 6,000 rpm and 650 pound-feet of torque at 4,000 rpm, that’s a pretty sizable jump, with an extra 133 horses and 120 pound-feet at max. All that newfound muscle comes by way of increased boost, with the Demon producing as much as 14.5 psi compared to the Hellcat’s 11.6 psi.

|Top Speed||190 MPH (est)||200 MPH|
Of course, power gains are meaningless unless they translate into more speed, and the Demon delivers with faster acceleration all around. The 0-to-60 mph time drops from 3.5 seconds in the Hellcat to just 2.3 seconds in the Demon, while the quarter miles drops from 11.2 seconds at 125 mph (10.8 seconds at 126 mph on drag radials) in the Hellcat to 9.65 seconds at 140 mph in the Demon. That also makes the Demon quicker in the 1320 than such heavy hitters as the McLaren P1 (9.8 seconds at 149 mph), The Porsche 918 Spyder (9.9 seconds at 146 mph), and Bugatti Veyron Super Sport (9.9 seconds at 146 mph).
That said, we’re still waiting on final numbers on the Demon’s top speed. We did a little speculation as to what that number might be, and long story short, we think that with the right conditions and proper tires, the Demon could achieve 190 mph flat out.
Sharper readers out there will point out how that makes the Demon about 10 mph slower than the less-powerful Hellcat, which is rated at about 200 mph in the top end. So what gives?
Sharper readers out there will point out that the Demon is about 10 mph slower than the less-powerful Hellcat.
The answer starts with the Demon’s rear end, which receives shorter gearing at 3.09, as compared to the Hellcat’s 2.62 final ratio. Throw in differences in tire size, redline, and most importantly, aero, and even an extra 133 horsepower won’t be enough to topple the Hellcat in a test of v-max.
Dodge focused entirely on making the Demon the king of the strip, and as such, included the “largest functional hood scoop opening” ever on a production car.
But that’s okay – the Demon is made to live a quarter mile at a time, so losing 10 mph off the top doesn’t really matter. Indeed, Dodge focused entirely on making the Demon the king of the strip, and as such, included the “largest functional hood scoop opening” ever on a production car. Which makes sense, given the Demon’s tendency to swallow atmosphere. Force feeding the blower is a 45.2 square inch hood scoop, while the triple-inlet air box is rated at 903.1 cubic inches. As a result, the airflow rate clocks in at a sizable 1,150 cubic feet per minute.
We can’t stop reading all the awesome tidbits Dodge is throwing our way with this powertrain spec sheet. Which numbers stand out to you? And more importantly, is the Demon worth an extra $20K over the “standard” Hellcat? Let us know in the comments section below.
