Dusterhoff Racing 877HP Hellcat Performance Power Package for 2015-2023 Dodge Challenger & Charger

Get ready to feel the earth tremble beneath your Hellcat with our Max Effort Pump Gas Hellcat Power Package!

The DT877 Hellcat Power Package from Dusterhoff Racing is a proven performance solution designed for 2015-2023 Dodge Challenger Hellcat and Dodge Charger Hellcat owners looking to unlock the full potential of their supercharged 6.2L HEMI engine. Instead of piecing together individual upgrades and hoping they work well together, the DT877 package combines carefully selected performance components and custom calibration strategies into a complete horsepower package. Designed using years of real-world testing and experience with Gen 3 HEMI platforms, this package provides enthusiasts with a reliable path toward increased power, improved drivability, and enhanced overall performance. Whether you’re building a street car, weekend drag racer, or roll-racing machine, the DT877 package delivers the performance gains Hellcat owners are looking for.

One of the biggest advantages of the DT877 package is its balanced approach to performance. Making more horsepower requires more than simply increasing boost pressure. Airflow, fuel delivery, tuning, and supporting modifications must work together to safely maximize performance. The DT877 package is engineered around this philosophy, ensuring every component complements the others while helping maintain reliability and consistency. This allows owners to enjoy substantial horsepower and torque gains without sacrificing the drivability that makes the Hellcat platform so enjoyable on the street.

• • Dusterhoff Tuning Upper Pulley Kit
  • HD Belt
  • 180 Thermostat
  • Fuel Injectors
  • PCM Unlock Service
  • RTD with credits
  • Smart Access Cable

This package makes around 100hp over stock.

The supercharged 6.2L Hellcat engine responds exceptionally well to properly designed performance upgrades. The DT877 package helps improve airflow, optimize engine calibration, and maximize supercharger efficiency to deliver stronger acceleration throughout the RPM range. Owners typically experience quicker throttle response, improved mid-range power, harder top-end pulls, and a more aggressive driving experience compared to stock. Whether launching from a stoplight, making a pass at the drag strip, or accelerating on the highway, the additional power is immediately noticeable.

Unlike generic performance combinations, the DT877 package is backed by Dusterhoff Racing’s extensive experience with Challenger and Charger Hellcat platforms. Every component is selected with performance, reliability, and compatibility in mind. This removes much of the guesswork commonly associated with building a modified Hellcat and gives owners confidence knowing their upgrades are designed to work together as a complete system. The package also serves as an excellent foundation for future upgrades such as flex fuel conversions, upgraded throttle bodies, ported superchargers, fuel system enhancements, and additional drivetrain modifications.

For enthusiasts seeking a complete performance solution capable of transforming their Hellcat into a significantly faster and more responsive vehicle, the DT877 package offers an ideal balance of power, reliability, and value. Browse our Hellcat Power Packages category to explore additional upgrade options designed specifically for Challenger and Charger Hellcat applications.

We are seeing that with higher-mileage cars, you might need to replace your fuel pump. If you would like, you can add a dual drop-in system to address these potential issues.
