Introduction: Why Supercharge a 2024 Jeep Wrangler JL?
For 2024 Jeep Wrangler JL owners, the search for more power is often driven by larger tires, heavier armor, or the desire for highway passing confidence. The factory 3.6L Pentastar V6 – the most common engine in the JL – produces 285 horsepower and 260 lb-ft of torque. While adequate, adding a supercharger transforms the driving experience, especially for those who tow, overland, or simply want quicker acceleration. Supercharging provides instant, linear boost without the lag of a turbocharger, making it the go-to forced induction method for off-roaders who need predictable power at low RPMs.
Two aftermarket supercharger kits dominate the Wrangler JL market in 2024: RIPP Superchargers and Edelbrock Superchargers. Both are specifically engineered for the Jeep Wrangler JL (2018–present), but they take very different approaches to delivering boost. This expanded guide breaks down their engineering, real-world power gains, installation requirements, tuning, and overall value to help you choose the right system for your build.
Supercharging Basics for the Wrangler JL
The Jeep Wrangler JL’s Pentastar V6 is an all-aluminum engine with a robust bottom end, but it was not originally designed for forced induction. Both RIPP and Edelbrock kits address the specific needs of this engine: lower compression ratio via thicker head gaskets (included in some kits), improved fuel delivery, and dedicated intercooling. Understanding the differences between supercharger types helps clarify why each brand makes certain design choices.
Centrifugal vs. Twin-Screw Superchargers
RIPP uses a centrifugal supercharger, which resembles a turbocharger but is belt-driven. It builds boost progressively with engine RPM, delivering peak power at higher engine speeds. This characteristic is excellent for highway merging and top-end horsepower. In contrast, Edelbrock uses a twin-screw (Roots-type) supercharger. Twin-screw designs provide instant boost from idle, offering massive low-end torque that is ideal for rock crawling and daily driving. However, they can generate more heat under sustained high-rpm use, which is why intercooling efficiency becomes critical.
Intercooling Strategies
Both kits include intercoolers, but they work differently:
- RIPP: Air-to-water intercooler with a dedicated heat exchanger and electric pump. This system maintains consistent intake air temperatures even in stop-and-go traffic or extended off-road use. The water carries heat to a front-mounted radiator.
- Edelbrock: Air-to-water intercooler integrated into the intake manifold. The self-contained oiling system also helps cool the supercharger unit. The heat exchanger is typically mounted in front of the radiator.
Proper intercooling is essential for preventing detonation on 91-octane pump gas, and both kits are tuned for safe operation without requiring race fuel.
RIPP Superchargers: High-RPM Power and Modular Tuning
RIPP has been a staple in the Jeep supercharger market for over a decade. Their JL kit is designed for owners who want the highest peak horsepower numbers and are willing to rev the engine to fully exploit the centrifugal design.
Power Gains and Dyno Results
On a stock 3.6L Pentastar with 91-octane fuel, the RIPP kit typically produces 420–440 horsepower at the crank (approx. 100–120 HP gain) and 390–410 lb-ft of torque. On the dyno, the torque curve rises steadily from 3,000 RPM and peaks near 5,500 RPM, while horsepower continues climbing to redline. This makes the RIPP-equipped JL feel strong in the upper mid-range and top end – a boon for highway passing and acceleration runs.
RIPP offers optional “Stage 2” upgrades including a larger intercooler, higher-flow injectors, and a revised pulley for more boost (6–8 psi). These can push output over 500 HP, but require supporting fuel system upgrades and a custom tune.
Installation and Kit Contents
The RIPP kit is a direct bolt-on system: no drilling, cutting, or permanent modifications required. The supercharger bracket mounts using existing accessory bolt holes, and the belt routing does not require a shorter belt. The kit includes:
- Vortech V3 Si centrifugal supercharger
- Air-to-water intercooler with pump and heat exchanger
- High-flow intake with reusable filter
- Fuel pressure regulator and upgraded fuel lines
- Handheld tuner with pre-loaded RIPP calibration
- All necessary hardware and installation manual
Most DIY mechanics can complete the installation in 8–12 hours. RIPP also provides remote tuning support for those who want to customize the calibration.
Tuning and Reliability
RIPP supplies a handheld tuner (SCT or DiabloSport) with their base calibration. The tune adjusts fuel maps, spark timing, and throttle response to match the supercharger. Long-term reliability is strong when using the included head gasket spacer (which drops compression) and sticking to the recommended octane. RIPP offers a 1-year warranty on the supercharger unit and 90 days on electronics.

Edelbrock Superchargers: Low-End Grunt and Seamless Integration
Edelbrock’s E-Force supercharger system for the JL is built around a twin-screw (Lysholm-type) compressor. It prioritizes low-RPM torque and seamless integration, often described as “factory feel.” This makes Edelbrock a popular choice for daily drivers and off-roaders who want immediate throttle response without waiting for RPMs to build.
Power Gains and Low-End Character
Edelbrock’s kit delivers approximately 385–405 horsepower at the crank (85–105 HP gain) and 380–400 lb-ft of torque. The key difference is where the power arrives: the twin-screw design produces 80% of its maximum torque below 3,000 RPM. In real-world terms, the Jeep feels significantly stronger from idle, making tire spins easier on loose surfaces and reducing the need to downshift on hills.
The torque curve is flat, with peak torque holding from 2,500 to 5,000 RPM. Horsepower peaks around 5,500 RPM. This distribution is ideal for off-road crawling and towing where low-RPM grunt is essential.
Self-Contained Oiling System
One of Edelbrock’s standout features is its self-contained oiling system. Unlike centrifugal superchargers that draw oil from the engine – requiring an oil supply line and drain – Edelbrock’s unit has its own oil reservoir and pump. This reduces the risk of oil leaks and simplifies installation. The system requires periodic oil changes (every 30,000 miles) but eliminates the need for engine oil connections.
Installation and Compatibility
The Edelbrock kit bolts onto a stock engine using all factory accessory locations. The included intercooler is integrated into the intake manifold casting, which keeps the package low-profile. Installation time is similar to RIPP (10–14 hours for first-time installers). The kit includes:
- E-Force twin-screw supercharger unit
- Air-to-water intercooler integrated into manifold
- Heat exchanger with electric fan
- High-flow fuel injectors
- Edelbrock calibration via handheld tuner
- New pulleys and belt
Edelbrock explicitly states their kit does not require any permanent modifications to the hood (no scoop needed), preserving the factory appearance.
Tuning and Warranty
Edelbrock’s tune is conservative, prioritizing safety and drivability over peak numbers. The kit includes an SCT X4 tuner with locked calibration (cannot be adjusted without unlocking by Edelbrock). However, many users report that the calibration is spot-on for pump gas. Edelbrock offers a 3-year/36,000-mile warranty on the supercharger – the longest in the industry.

Real-World Performance Testing
Numbers on paper only tell part of the story. Here is how both kits perform in typical driving scenarios.
0–60 MPH and Quarter-Mile
A stock JL 3.6L runs 0–60 in about 6.5 seconds. With the RIPP kit, times drop to ~5.0–5.2 seconds. The Edelbrock kit achieves similar 0–60 times (~5.1–5.3 seconds) despite lower peak HP because the low-end torque helps launch harder. Quarter-mile trap speeds favor RIPP by 2–3 mph, typically reaching 108–110 mph vs. 105–107 mph for Edelbrock.
Off-Road and Rock Crawling
In low-range gearing, the Edelbrock’s instant torque makes it easier to crawl over obstacles without stalling. The throttle remains responsive even at 1,500 RPM. The RIPP kit, while providing excellent high-rpm power in the dunes or on fire roads, requires a more deliberate throttle input in technical terrain to keep the revs up. Many serious rock crawlers prefer Edelbrock for this reason.
Towing
Both kits improve towing performance (JL’s max is 3,500 lbs). The Edelbrock provides better pull-away from a stop, reducing the downshifting needed on inclines. The RIPP maintains speed better on highway grades due to its top-end power reserve. For towing heavy trailers over mountain passes, either kit is a significant upgrade over stock.

- Budget is slightly lower, and you don’t need the longer warranty.
Choose Edelbrock if:
- Low-end torque and instant throttle response are your top priorities (crawling, daily driving).
- You value a “factory” integration with no hood modifications and a self-contained oil system.
- You want the longest warranty and conservative tuning that prioritizes reliability.
- You do moderate towing or off-roading at varied speeds.
- You don’t plan to push power beyond the baseline kit.
Final Thoughts
The RIPP and Edelbrock superchargers are both exceptional products that transform the Jeep Wrangler JL into a genuinely quick vehicle. In 2024, the competition has forced both companies to refine their offerings: RIPP now includes a better intercooler and more robust tuning support, while Edelbrock has improved the packaging and warranty. There is no “wrong” choice here, only a choice that aligns with your specific performance needs.
Before purchasing, confirm compatibility with your JL’s engine (3.6L Pentastar only – not compatible with 2.0L turbo or 392) and any other modifications such as exhaust or cold-air intakes (both kits work with most aftermarket cat-back exhausts). Also factor in the cost of professional installation if you are not experienced with supercharger installs.
For the 2024 build season, both kits remain the gold standard. Whether you chase high-rpm horsepower or low-end torque, your Wrangler will feel like an entirely different machine.
