Witnessing the introduction of a groundbreaking, drag strip-conquering Dodge Demon might evoke a sense of déjà vu. In 2017, Dodge revealed the original Demon, which flaunted 808 horsepower from its monstrous supercharged V8 engine and numerous production car drag strip accolades. Now, enters the new Dodge Demon 170, appearing to mirror its predecessor’s achievements. So, what sets this fresh model apart mechanically from its predecessor?
In essence, it retains the essence of the former Demon but in a more heightened manner. It remains a meticulously tuned Challenger boasting mind-boggling figures and asterisks galore. The key dissimilarity lies in the Demon 170’s even more astounding statistics when compared to its forerunner. Here’s a glimpse of the standout numbers: 1,025 horsepower, 945 pound-feet of peak torque (on an E85 ethanol blend), 0-60 mph in a blazing 1.66 seconds, and a quarter-mile sprint certified by NHRA in 8.91 seconds at 151.17 mph. Truly mind-blowing figures.
Despite the familiar 6.2-liter displacement, the new Demon 170’s V8 engine shares more similarities with the Hellephant crate engine than its predecessor’s V8. Virtually every significant engine component in the Demon 170 has been revamped, with only the camshaft remaining as a major carryover part.
The 3.0-liter supercharger underwent modifications, including a 105mm throttle body and a 3.02-inch diameter pulley. It now features nitride-coated intake valves with upgraded valve guides, copper-lead main and rod bearings, reinforced connecting rods, high-strength steel cylinder head studs of aerospace grade that boost clamp load by 38%, and a cylinder pressure 32% higher compared to the Hellcat Redeye Widebody’s.
One of the most remarkable upgrades to the Demon 170’s powerplant is its fuel injectors. The new high-flow fuel injectors can deliver a staggering 164 gallons per hour, surpassing the flow rate of a typical U.S. shower head. To optimize combustion of the ethanol-rich fuel, new spark plugs with a lower heat range were introduced. The engine’s software can detect ethanol levels in the fuel, and when it reaches 65% or more, the fuel gauge icon on the dashboard turns blue, indicating the full 1,025 hp is ready. If ethanol levels drop below 20%, the gas icon turns white, limiting power to a “mere” 900 hp and 810 lb-ft.

However, Dodge didn’t focus solely on upgrading the engine. The driveshaft is now 30% more durable than before, while the rear axle housing is bolstered by 53% with aerospace-grade materials. Produced using HIP (Hot Isostatic Pressing) to enhance strength and reduce porosity compared to casting, the rear axle features a 240mm ring and pinion, a fresh input flange, and a larger CV joint. The rear axle half shafts were also reinforced, with increased shaft diameters and larger joint splines.
The rear suspension camber was adjusted to enhance tire contact patches. Speaking of tires, the rear wheels are 17×11 inches shod with Mickey Thompson P315/50R17 ET Street R drag radials, while the front wheels are 18×8 inches fitted with Mickey Thompson 245/55R18 ET Street tires. These wheels are Lacks Enterprises two-piece carbon fiber wheels, contributing to a total weight reduction of 157 pounds in the Demon 170 compared to the Hellcat Redeye.
These remarkable specifications culminate in extraordinary numbers, albeit with some caveats. Achieving those insane times—1.66 seconds to 60 mph and 8.91 seconds in the quarter-mile—demands non-street legal drag radials on a specially prepped surface. Thus, as impressive as its performance may be, it’s tailored for the drag strip ambiance.
However, that detail is inconsequential, isn’t it? The Demon 170 embodies the peak of internal combustion eccentricity, captivating all with its awe-inspiring presence.
