How much horsepower does a supercharged Charger have?

The peak factory horsepower for a Charger with a supercharged V8 sits at 807 horsepower in the 2023 SRT Hellcat Jailbreak, with 797 horsepower in the Hellcat Redeye and 707 horsepower in the standard Hellcat. Since Dodge ended Charger production after 2023, these figures represent the final and most powerful factory option for the model.

Official horsepower by Charger variant

Below are the primary factory horsepower ratings for Dodge Charger models equipped with the 6.2-liter supercharged Hemi V8. These figures reflect the main high-performance trims that defined the Charger lineup in its supercharged era.

• Charger SRT Hellcat — 707 horsepower (6.2L supercharged V8), available roughly 2015–2019 models.


• Charger SRT Hellcat Redeye — 797 horsepower (6.2L supercharged V8 with higher-output tune), available 2019–2023 models.


• Charger SRT Hellcat Jailbreak — 807 horsepower (6.2L supercharged V8 with calibration and exhaust upgrades), available 2023 models.

These figures capture the main factory ratings for the Charger’s supercharged lineup. Real-world output can vary by year, market, and configuration, but these are the official numbers Dodge published for each trim. The Charger line ceased production after the 2023 model year, marking the end of new supercharged Charger variants from the factory.

Context and performance implications

horsepower is only part of the story. Torque, weight, aerodynamics, traction, and gearing all influence actual acceleration and on-road performance. The Jailbreak variant offered the highest peak output, while the Redeye delivered substantial, more tractable all-around power for most drivers. The standard Hellcat provides a still-robust level of performance for enthusiasts seeking extreme speed from a factory Charger.

How horsepower is measured

Factory horsepower figures are typically quoted as engine crank horsepower. Real-world wheel horsepower can be lower due to drivetrain losses, tire choice, and testing conditions. The numbers above reflect Dodge’s official ratings for each trim.

Production status and history

Charger production ended after the 2023 model year. There have been no new factory supercharged Chargers released since then, making the 2023 Jailbreak the final peak in Dodge’s Charger horsepower lineup.

Summary

In summary, a supercharged Charger ranges from 707 horsepower in the base Hellcat to 807 horsepower in the final Jailbreak edition, with 797 horsepower in the Redeye variant. The Charger’s V8 supercharged era culminated in 2023, ending a notable chapter in American muscle.

How much HP would a supercharger add?

A supercharger can add anywhere from 50 to over 200 horsepower, with typical gains of 35% to 50% of a vehicle's stock output, depending on the specific engine, supercharger kit, and amount of boost pressure. Some kits are designed for significant increases, like adding over 150 horsepower to a Mustang GT or over 160 horsepower to a 5.7L HEMI engine. 

• Average gains: A general estimate is a 35% to 50% increase over the engine's stock horsepower. 
• Example applications:
  • A 5.7L HEMI engine can gain over 160 HP with a high-quality supercharger kit. 
  • A Mustang GT can potentially add over 200 horsepower. 
  • A Dodge Charger can see gains of 100 to over 200 horsepower. 
• Factors influencing gain: The exact horsepower increase depends on several factors, including the specific engine, the type of supercharger kit, the amount of boost pressure (psip s i𝑝𝑠𝑖), and whether an intercooler is used to cool the compressed air. 
• Engine and driveline stress: It's important to remember that increasing horsepower puts more stress on the engine and other components, so it is crucial to ensure the vehicle is built to handle the added power. 

Can I supercharge a 3.6 L V6?

Yes, you can supercharge a 3.6L V6 engine, with companies like RIPP and ProCharger offering complete bolt-on kits for popular models like the Dodge Challenger and Jeep Wrangler. These kits increase horsepower and torque, turning the V6 into a more powerful engine, sometimes with performance comparable to a V8.

What a supercharger does

• A supercharger is a form of forced induction that compresses more air into the engine's cylinders. 
• This allows more fuel to be burned, resulting in a significant increase in horsepower and torque. 
• Some kits can provide a 40% to 60% increase in horsepower. 

What's included in a kit

• Supercharger unit: The main component that compresses the air. 
• Intercooler: Helps cool the compressed air before it enters the engine, which increases density and power. 
• Charge piping: Connects the components of the system. 
• Engine management: This often includes a new tune and sometimes requires an unlocked PCM (Powertrain Control Module) to adjust for the increased performance. 
• Fuel injectors and sensors: Upgraded components to ensure the engine has the right amount of fuel for the increased air intake. 

Important considerations

• Professional installation: While some kits are designed for DIY installation, professional installation is often recommended to ensure everything is done correctly. 
• Tuning: Proper tuning is crucial for performance and engine health. Some kits include a tune, but professional dyno testing is often required to optimize the setup for your specific vehicle. 
• Vehicle compatibility: Kits are designed for specific models and model years, so make sure the kit you choose is compatible with your car or truck. 
• Cost: Kits can be a significant investment, with some base kits costing around $6,200, not including installation.

How much HP does a supercharged 5.0 have?

It brings it to 700 horsepower 590 lb feet of torque. Now all that power does go through a 10-speed transmission. And this engine is port and direct injection.

How much HP does a supercharged 5.7 Hemi make?

A supercharged 5.7 Hemi can produce anywhere from approximately 500 to over 600 horsepower, depending on the specific kit, boost levels, and other modifications. Bolt-on kits for a stock 5.7 Hemi can add around 140-160+ horsepower, leading to a total output in the 500-550 hp range, while more extreme setups can achieve even higher numbers.

Estimated horsepower gains by application

• Bolt-on kits: Adding around 140 to 160+ hp to a stock 5.7 Hemi, pushing the total to roughly 515 to 535 hp and beyond. 
• Custom builds: With more advanced setups, including forged components, cams, and higher boost, achieving over 500 wheel horsepower is achievable, which translates to approximately 600+ horsepower at the crank. 
• Specific kits:
  • Hamburger's Superchargers: Offers a Stage I kit that adds approximately 140 horsepower, resulting in a total of about 575 hp for the 2015-19 Dodge Ram. 
  • ProCharger: Advertises 160+ hp gains for the 5.7L Hemi with their systems. 
  • RIPP Supercharger: Has dyno-proven kits that can deliver around 528 wheel horsepower (whp) and 504 lb-ft of torque. 
• Important factors: The final output is heavily influenced by the specific supercharger kit, the boost pressure, the fuel used (e.g., 91 octane vs. E85), and other supporting modifications like the fuel system, intake manifold, and camshaft.
