Which Dodge engine has the most horsepower?
The Dodge engine with the most horsepower ever produced is the 6.2-liter supercharged Hemi V8 used in the Challenger SRT Demon, rated at 840 horsepower (SAE net 808 hp) when running on high-octane fuel. For currently available production models, the peak is about 807 horsepower in the Challenger SRT Jailbreak variant, with the Hellcat lineup reaching up to around 797 horsepower in Redeye configurations.
All-time horsepower leader and current production peak
Below is a concise look at Dodge’s most powerful engines, spanning the brand’s modern era and limited-run performance cars. The numbers reflect Dodge’s official horsepower ratings and vary with octane fuel and testing standards.
- Dodge Challenger SRT Demon — 6.2L Hemi V8 Supercharged — 840 hp (SAE net 808 hp) with 100+ octane fuel; torque around 770 lb-ft; limited to 3,300 units produced in 2018.
- Dodge Challenger SRT Hellcat Redeye Widebody — 6.2L Hemi V8 Supercharged — 797 hp (SAE net); standard Hellcat variants deliver 707 hp; introduced as the high-performance Redeye option in 2019.
- Dodge Challenger SRT Jailbreak — 6.2L Hemi V8 Supercharged — up to 807 hp (SAE net) with 93-octane fuel; limited-production option offered around 2022–2023.
These figures illustrate the range from the Demon’s extreme, limited-run horsepower to the top-end numbers Dodge has offered in street-legal, mass-produced variants in recent years. The Demon remains the benchmark for peak horsepower, though it is no longer in regular production.
How horsepower is rated and what it means for Dodge engines
Horsepower figures for these Dodge engines are typically SAE net ratings, which account for standard accessory loads and real-world conditions. The Demon’s 840 hp label is often cited with 100-octane race fuel, while the SAE net rating sits at 808 hp. The Jailbreak and Redeye figures reflect high-performance tuning under specific octane conditions. In short, the Demon represents Dodge’s all-time horsepower high, while the Jailbreak and Redeye models represent the contemporary production ceiling.
Context and implications for buyers and enthusiasts
For enthusiasts shopping today, the practical takeaway is that Dodge’s modern lineup tops out around 797–807 hp in the Hellcat family, with the Demon serving as a historic outlier that achieved 840 hp under restricted, limited-run conditions. Real-world performance also depends on gearing, traction, weight, and fuel quality, not horsepower alone.
Summary
In summary, the highest horsepower ever produced by a Dodge engine is the 6.2L supercharged Hemi V8 in the Challenger SRT Demon at 840 hp (SAE net 808 hp). Among current production models, the strongest official rating is up to 807 hp in the Jailbreak variant, with the Hellcat Redeye capable of about 797 hp. These figures reflect Dodge’s performance-focused approach, balancing extreme power with drivability and track capability.

Is a 392 the same as a 5.7 HEMI?
No, a 5.7L HEMI is not a 392; a 392 is a larger 6.4L HEMI engine. The "392" refers to the 392 cubic inches of displacement, while the 5.7L engine is approximately 345 cubic inches (5.7×61.024=347.85.7 cross 61.024 equals 347.85.7×61.024=347.8 cubic inches).
- 5.7L HEMI: This engine displaces approximately 345 cubic inches and is a common V8 found in many trucks and cars.
- 392 HEMI: This is a larger, more powerful 6.4L engine that displaces 392 cubic inches and is used in performance models like the SRT 392 and Scat Pack.
What's the difference between a Dodge 440 and a 440 Magnum?
There ultimately is very little difference between the Mopar 440 and the Mopar 440 Magnum. The Magnum designation simply meant that it was the high-performance version of the V8 engine. An important note is that this also meant it was in a Dodge vehicle.
