The 5.7-liter Hemi V8 has been a staple of Chrysler, Dodge, and Ram vehicles for nearly two decades, earning a loyal following among enthusiasts who appreciate its combination of displacement, torque, and surprising fuel efficiency. From the Dodge Charger R/T to the Ram 1500, this engine provides a robust foundation for performance upgrades. Whether you’re building a weekend drag car, a daily driver with extra grunt, or a tow rig that needs more low-end power, aftermarket components from trusted brands can transform the driving experience. In this guide, we explore three top-tier brands—Edelbrock, Mopar, and Ripp Performance—each offering distinct pathways to enhanced horsepower, torque, and reliability for your 5.7 Hemi.

Edelbrock: Over a Century of Airflow Expertise

Founded in 1938, Edelbrock has built a reputation for precision-engineered intake manifolds, cylinder heads, and fuel systems. Their 5.7 Hemi lineup focuses on improving volumetric efficiency—getting more air and fuel into the combustion chamber and expelling exhaust gases more freely. Edelbrock parts are known for bolt-on simplicity and dyno-proven gains, making them an excellent choice for DIY builders and professional shops alike.

Intake Manifolds

Edelbrock’s Performer RPM and Victor Series intake manifolds are specifically cast for the 5.7 Hemi’s cylinder head port geometry. These manifolds replace the factory plastic intake to reduce heat soak and increase plenum volume. The result is improved mid-range torque and throttle response, especially when paired with a free-flowing exhaust. Edelbrock also offers fuel rail kits and gaskets designed for a seamless installation.

Camshafts and Valvetrain

For those wanting a more aggressive power curve, Edelbrock supplies camshafts tailored to the 5.7 Hemi’s variable valve timing (VVT) system. Their cams increase lift and duration while maintaining proper overlap for emissions compliance in many states. Additionally, Edelbrock’s cylinder heads are available assembled with upgraded springs and retainers, ready for high-rpm use. These components work in tandem to unlock 40–70 horsepower over stock, depending on supporting modifications.

Fuel System Upgrades

Edelbrock’s fuel system components include high-flow injectors and in-tank pump modules that support up to 700 horsepower. Their EcoTEC electronic fuel injection (EFI) systems are also adaptable to the 5.7 Hemi, offering self-learning tuning for forced induction applications. Reliability is a key focus: all Edelbrock fuel parts undergo rigorous testing to ensure consistent fuel delivery under high engine loads.

Installation Considerations

Most Edelbrock upgrades are designed for bolt-on installation with standard hand tools. However, cam swaps require engine timing chain replacement and careful VVT phaser clocking. Edelbrock provides detailed instructions and technical support, and many enthusiasts choose to have professional tuning done after installation to fully optimize air/fuel ratios.

Mopar: Factory-Engineered Performance and Reliability

As Chrysler’s official performance parts division, Mopar offers upgrades that are engineered to integrate seamlessly with the 5.7 Hemi while maintaining factory durability and warranty compatibility. Mopar parts are often the first choice for owners who want a guaranteed fit, minimal downtime, and performance that doesn’t sacrifice everyday drivability.

Complete Performance Kits

Mopar’s Mopar Performance Kits combine intake, exhaust, and calibration upgrades into a single package. For example, the 5.7 Hemi “Stage 1” kit includes a cold air intake, cat-back exhaust system, and a performance engine controller calibration. These kits are EPA-compliant in all 50 states and can add 30–50 horsepower without voiding the vehicle’s powertrain warranty when installed by an authorized dealer.

Cold Air Intakes and Induction

Mopar’s cold air intake systems feature a sealed housing that draws cooler air from outside the engine bay, reducing intake air temperatures by up to 20°F. The high-flow filter is washable, and the intake tube maintains optimal mass airflow sensor readings. This upgrade not only increases horsepower but also improves fuel economy during normal driving.

Exhaust Systems

The Mopar cat-back exhaust uses mandrel-bent tubing and a free-flowing muffler to reduce backpressure. Sound levels are aggressive but refined—no drone at highway speeds. Mopar also offers stainless steel systems with polished tips that integrate into the factory exhaust hangers for a clean install. Pairing the exhaust with the cold air intake yields the most noticeable butt-dyno improvement.

Electronic Calibration and Tuning

Mopar’s performance calibration modules (PCM flash) adjust fuel maps, ignition timing, and throttle response. These modules are vehicle-specific and can be updated at dealerships. Unlike generic tuners, Mopar’s calibration is validated for smog legality and driveline protection. It’s the safest way to unlock hidden power while keeping engine stress within design limits.

Ripp Performance: Forced Induction Authority

For enthusiasts who want dramatic power gains—often doubling factory output—Ripp Performance has become the go-to source for supercharger systems and supporting components. Their expertise in positive-displacement and centrifugal superchargers yields reliable power that can exceed 600 wheel horsepower on a stock bottom 5.7 Hemi.

Supercharger Kits

Ripp’s Gen II and Gen III supercharger kits are designed specifically for the 5.7 Hemi’s VVT and are available for both LX/LC platform cars (Charger, Challenger, 300) and Jeep Grand Cherokee WK2. The kits include a cast-aluminum intake manifold, intercooler, fuel injectors, and a drive system with a premium cog belt. Boost levels range from 6 to 12 psi depending on the pulley used. With proper tuning, Ripp superchargers can add 150–250 horsepower to the wheels.

Tuning Solutions

Ripp provides engine management tuning through their proprietary Ripp Cable Tuning (RCT) system or via compatibility with DiabloSport and HP Tuners. They offer remote tuning support and base calibrations that allow the engine to start and idle smoothly. Advanced users can data-log and send logs for refinement. Ripp’s tuning calibrations include safeguards like knock control and fuel trims critical for forced induction.

Performance Accessories

To support the extra power, Ripp sells upgraded intercoolers, high-flow fuel rails, and billet aluminum throttle bodies. They also offer heavy-duty serpentine belt systems that prevent slip under high boost. For automatic transmission vehicles, Ripp recommends their torque converter upgrade and transmission cooler kits to handle the increased torque.

Labor costs vary by region; expect 8–12 hours for supercharger installation and 4–6 hours for cam swaps.

Horsepower Expectations

A naturally aspirated build with Edelbrock or Mopar parts (intake, exhaust, tune) typically yields 360–420 wheel horsepower (whp) from a stock 350–370 whp 5.7 Hemi. With a mild cam and supporting mods, you can reach 450–480 whp. Ripp’s supercharger kits push into the 500–650 whp range on pump gas, and with E85 fuel and upgraded internals, over 700 whp is achievable.

Installation Tips for 5.7 Hemi Upgrades

Regardless of brand choice, several best practices apply:

  1. Check VVT Compatibility – Many 2009+ 5.7 Hemis use variable valve timing. Aftermarket cams and cylinder heads must be VVT-ready or you’ll need a phaser lockout kit (which loses variable timing).
  2. Upgrade Fuel System Early – Forced induction or aggressive cam profiles often exceed the capacity of the factory fuel pump and injectors. Install a 525–550 lph fuel pump and 50–80 lb/hr injectors to stay safe.
  3. Use a High-Quality Tuner – Even “plug-and-play” kits benefit from professional calibration. Remote tuning services are available from Hemi specialists who can dial in idle, cold starts, and wide-open-throttle fuel mapping.
  4. Consider Transmission Support – The ZF 8-speed or NAG1 automatic transmissions may need a torque converter upgrade and transmission cooler if your power goal exceeds 500 ft-lb of torque at the wheels.
