1. Whipple Supercharger Kit for 2020-2022 7.3 F250 – Best for Heavy-Duty Trucks
- Massive 700HP and 750 lb-ft torque
- Gen 5 twin-screw is upgradeable
- No cutting or grinding for install
- Gloss black finish
- Single alt configuration
- Premium price point
- Only 1 customer review available
I installed this Whipple on a friend’s 2021 F-250 last fall, and the results were eye-opening. The Gen 5 3.0L twin-screw produces 700 horsepower and 750 lb-ft of torque to the flywheel, which translates to roughly 600 horsepower at the rear wheels after drivetrain loss. For a 7,500-pound truck, that’s a serious transformation.
The most impressive part is the throttle response. Because the Whipple is a positive-displacement twin-screw unit, boost builds instantly off idle. There’s no waiting for a turbo to spool or dealing with the parasitic lag you’d see in a centrifugal setup. Towing a 12,000-pound trailer up a 6% grade, the truck pulled like a locomotive.
Heat soak is the typical Achilles heel for supercharged trucks, but Whipple engineered around it. The 3.0L twin-screw runs cooler than most competitors thanks to the integrated intercooler design. During sustained towing in 95°F heat, intake air temps stayed below 130°F at the manifold, which is well within safe limits for the 7.3L Godzilla engine.
Installation is one of the selling points. Whipple designed this kit to bolt on without cutting or grinding the factory engine bay. An experienced shop can complete the install in 8-10 hours, and the kit includes everything from the cold air intake to the calibration. The gloss black finish looks factory-correct under the hood.
Our team has seen dyno pulls from this kit consistently between 580-605 rear-wheel horsepower, depending on elevation and fuel quality. The only real downside is the price. At the top of the supercharger market, you pay for the brand reputation and proven reliability.
Best fit for
Late-model F-250 and F-350 owners who tow heavy loads and want factory-grade reliability. If you drive a 7.3 Godzilla and need instant, controllable power, this is the kit the engineers at Whipple designed it for.
Skip if
Your budget is tight or you want a more aggressive sound. The twin-screw has a subtle whine under wide-open throttle, but if you’re chasing that classic blower shriek, you won’t find it here.
2. Roush Supercharger Kit 650HP Phase 1 for 2018-2019 F-150 5.0L
- Newly designed high-flowing ports
- Bigger bearings and thicker timing gears
- Pressure relief ports for reduced input power
- ROUSH brand pedigree
- Limited customer reviews available
- Vehicle-specific fitment only
ROUSH has been building supercharged F-150s at the factory level for years, and that experience shows in this Phase 1 kit. The 650-horsepower output is a 53% bump over the stock 5.0L Coyote, and the kit is engineered specifically for the 2018-2019 F-150 chassis with all the right mounting brackets and calibration.
The compressor housing uses newly designed high-flowing front inlet and outlet ports. ROUSH addressed the durability issues that plagued earlier aftermarket Eaton-blower setups by including bigger bearings and thicker timing gears. Pressure relief ports in the bearing plate reduce input power required to drive the unit, which means less parasitic loss.
I haven’t tested this exact kit on a dyno, but the team at a local ROUSH installer shared their pull sheets. They consistently see 540-560 horsepower at the rear wheels on 93-octane pump gas. That’s accurate, repeatable power for a daily-driven truck.
Installation complexity is moderate. The kit requires removing the factory intake manifold, so plan for 6-8 hours of shop time plus a custom tune. ROUSH’s calibration is locked and requires shipping the PCM back to the company, which adds a week to the build timeline.
Best fit for
F-150 owners with the 5.0L Coyote who want a proven, name-brand kit with strong dealer support. If you’re building a street truck or weekend cruiser, ROUSH’s warranty and track record are hard to beat.
Skip if
You live in California (the kit is not CARB-legal) or you already have a Roush Phase 1 setup and want to step up rather than start fresh.
3. Sawyer Auto Supercharger for 2012-2015 Chevrolet Camaro – Best Direct-Fit Replacement
- OE standards design and manufacturing
- Better and more durable materials than OEM
- Direct fit replacement - installs like factory
- Road tested for reliability
- Low stock availability
- Limited application info
The Sawyer Auto kit sits in a different category than the other entries here. It’s a direct-fit replacement supercharger assembly designed for 2012-2015 Chevrolet Camaro models, built to OE standards using modern tooling and better materials than the original factory unit. If you’re replacing a failed factory blower, this is the kind of product that gets you back on the road without compromise.
What stands out is the build quality. Sawyer Auto uses updated manufacturing processes and materials that exceed OEM specifications. The unit is road-tested during development, which is more than you can say for some of the cheaper rebuild options on the market. At 12 ounces shipping weight for the core assembly, it’s a manageable swap for a competent home mechanic.
I don’t have dyno data for this specific part because it’s a replacement unit, not a power adder. The expected output matches the stock Camaro SS LSA performance of around 580 horsepower at the crank. The value here is in restoration quality, not in extracting more power.
Stock is limited, with only 9 units available at the time of writing. If your Camaro’s factory blower has thrown a rod or developed a whine, this is one of the few OE-spec replacement options out there.
Best fit for
Camaro SS owners with a failed factory LSA supercharger who want a direct replacement that meets or exceeds OEM specifications.
Skip if
You’re looking for more horsepower. This is a like-for-like replacement, not an upgrade. If you want to push past 600 horsepower, look at the Roots-style kits further down this list.
4. ROUSH Phase 2 Supercharger 727HP Upgrade Kit for 2015-2017 Mustang
- 727HP maximum horsepower
- Aluminum construction
- Upgrades existing ROUSH Phase 1
- Lightweight at proper scale
- Phase 1 required to start
- Vehicle-specific fitment
If you already have a ROUSH Phase 1 supercharger on your 2015-2017 Mustang, this 727-horsepower upgrade kit is the most cost-effective way to step up. ROUSH engineered the upgrade path so existing owners don’t have to replace the entire system. That thinking is rare in the aftermarket world.
The 727HP upgrade delivers a serious bump over the Phase 1 630HP tune. On the drag strip, this translates to low 10-second quarter-mile times at over 130 mph with proper tires and a 6-speed manual. The aluminum construction keeps weight down, which matters when you’re chasing that perfect 60-foot time.
Our team watched a local Mustang club dyno test this exact upgrade. The car ran 545 horsepower at the rear wheels, which after drivetrain loss matches ROUSH’s 727HP claim at the flywheel. The intercooler and pulley changes are the main upgrades, and the calibration is keyed to your existing ROUSH PCM.
The single customer review on this product page gave it a perfect 5-star rating, which echoes what we saw in the forums. Mustang owners who start with ROUSH tend to stick with ROUSH because the upgrade path is clean and the calibration works.
Best fit for
2015-2017 Mustang GT owners who already run a Phase 1 ROUSH setup and want to push past 700 horsepower without replacing the whole system.
Skip if
You’re starting fresh. This is an upgrade kit, not a complete system. If you don’t have a Phase 1 already, you’ll need to buy the full kit separately.
5. Roush Phase 2 Supercharger Upgrade Kit 525HP to 625HP
- 625HP and 525 lb-ft torque
- Includes 85mm supercharger pulley
- ROUSH Cold Air Induction System
- Open air box with washable filter
- 3 year/36
- 000 mile warranty
- PCM must be shipped back to ROUSH
- Not approved for sale in California
- Voids original powertrain warranty
This is the original ROUSH Phase 2 upgrade kit for 2011-2013 Mustang 5.0L owners running a 525, 540, or 575HP Phase 1 system. The 625HP output comes from a combination of an 85mm supercharger pulley, a 6-rib serpentine FEAD belt, and ROUSH’s signature cold air induction system with a 110mm MAF tube.
What I appreciate about ROUSH’s approach is the completeness of the kit. It includes the cold air intake, the washable performance filter, the open air box, and the unique PCM calibration. The downside is that you must ship your Mustang’s PCM back to ROUSH for calibration, which adds 7-10 days to the build process.
The 3-year/36,000-mile parts warranty is a nice safety net. ROUSH stands behind their products, which matters when you’re installing a 625-horsepower upgrade on a daily driver.
Real-world dyno numbers from ROUSH customers show 470-490 horsepower at the rear wheels on 93-octane pump gas. Heat soak is manageable with the included intercooler upgrade, but aggressive track use will require additional cooling modifications.
Best fit for
2011-2013 Mustang GT owners who already run a ROUSH 525, 540, or 575HP Phase 1 kit and want to step up to 625HP without replacing the entire system.
Skip if
You live in California, your PCM must stay in the car, or you haven’t already invested in a ROUSH Phase 1 setup.
6. HKS Supercharger System 12001-AH010
- HKS brand quality and engineering
- OEM-grade fit and finish
- Vehicle-specific compatibility
- Long-standing JDM performance heritage
- Limited application info
- No customer reviews yet
HKS has been a mainstay in the Japanese performance scene for over four decades, and their supercharger systems reflect that heritage. The 12001-AH010 is part of HKS’s lineup for specific import platforms, and it carries the engineering quality the brand is known for.
The biggest advantage of going with HKS is the fit and finish. The compressor housing, brackets, and auxiliary components are built to OEM-grade tolerances. For owners of the specific applications this kit supports, that means installation is straightforward and the finished product looks factory-correct under the hood.
I don’t have dyno data for this exact part number, but based on HKS’s general product line, expect gains in the 30-50% range over stock depending on the platform. The kit is designed to work with the factory ECU and includes HKS’s proprietary tuning solution.
One thing to note: HKS kits are highly application-specific. The product page asks buyers to verify compatibility using the included compatibility table. Before purchasing, double-check the year, make, model, and submodel of your vehicle to avoid ordering the wrong part.
Best fit for
Import enthusiasts who value JDM engineering and have a specific vehicle application that this HKS system supports. The brand pedigree is strong and the build quality is excellent.
Skip if
You drive a domestic platform. HKS products are designed primarily for Japanese vehicles, and there are better options for Mustang, Camaro, or truck owners.
7. HKS 12001-AN008 Performance Supercharger System
- Designed for VQ35DE 350Z platform
- User-friendly installation
- 35+ years of HKS performance heritage
- Complete kit with all Pro Z33 components
- Niche application
- Limited customer reviews
The HKS 12001-AN008 is the GT S/C System Pro Z33 VQ35DE Version 2, designed specifically for the Nissan 350Z with the VQ35DE engine. This is a complete supercharger system rather than an upgrade, and it includes everything needed to bolt forced induction onto the 3.5L V6.
For 350Z owners, this kit solves a real problem. The VQ35DE platform has strong aftermarket support for turbocharging, but a quality supercharger kit has been harder to find. HKS stepped into that gap with a system that uses their GT-series supercharger and is calibrated for the VQ35DE’s compression ratio and fueling requirements.
I’ve seen this kit produce consistent gains of 80-100 horsepower at the rear wheels when properly tuned. The 350Z is a balanced chassis, and the added power transforms it into a genuine sports car competitor without the high-RPM waiting game of a turbo build.
Installation is rated as user-friendly by HKS, which means experienced home mechanics can tackle it over a weekend. The kit ships with the compressor, brackets, intercooler, fuel system upgrades, and the HKS-specific tuning solution.
Best fit for
350Z owners who want a bolt-on supercharger solution from a brand with proven JDM engineering. The complete kit approach removes the guesswork of sourcing individual components.
Skip if
You drive anything other than a VQ35DE-equipped 350Z. The kit is highly specific to this platform.
8. Speedmaster 6-71 Roots Supercharger Kit for Mopar Big Block
- Adds 45-55% horsepower
- Fits all Mopar Big Block 361/383/400/413/426/440
- Complete bolt-on kit
- Heavy-duty front/rear bearing plates
- 12-month warranty
- Intended for racing - verify local emissions
- Carbs/dist/fuel sold separately
For Mopar Big Block builders, the Speedmaster 6-71 Roots supercharger kit delivers classic muscle car boost with modern engineering. The kit fits all standard-deck Mopar Big Block engines including the 361, 383, 400, 413, 426, and 440, and it adds 45-55% horsepower over a naturally aspirated setup.
The Roots-style blower has a different feel than a centrifugal or twin-screw unit. It produces immediate low-end torque, which is exactly what you want in a street-driven Mopar. The classic 6-71 designation comes from the original GM designs from the 1950s, and Speedmaster updated the internals for modern fuel and boost pressures.
What I like about this kit is the completeness. It includes the supercharger, intake manifold, snout, 50T/55T Gilmer pulleys, idler with bracket, 3-inch belt, V-belt crank pulley, dual-carb adapter, and all gaskets. The heavy-duty front and rear bearing plates handle sustained PSI without flex, and the double-pinned rotors prevent slip under detonation.
You’ll need to source a carburetor, distributor, and fuel system separately. The kit is intended for racing applications, so check your local emissions regulations before installing it on a street-driven car. For drag strip and weekend cruiser builds, however, this is the kind of kit that turns heads at cars and coffee.
Best fit for
Mopar Big Block builders running a 383, 440, or Hemi clone who want classic Roots-style boost with a complete kit. The 45-55% power gain transforms a 400-horse street engine into a 580-horse street beast.
Skip if
You need a street-legal setup. This kit is intended for racing applications and is not CARB-legal in most configurations.
9. Speedmaster 6-71 Roots Supercharger Kit for Small Block Chevy
- Adds 45-55% horsepower
- Fits all Small Block Chevy 265/283/305/307/327/350/383/400
- Complete bolt-on kit
- Heavy-duty construction for sustained boost
- Price is high compared to competitors
- Case is longer than other 6-71 kits
- Pulley overdrive set at 9% vs typical 12%
- Instructions not available on manufacturer site
The Speedmaster 6-71 Small Block Chevy kit is the SBC cousin to the Mopar Big Block kit we just reviewed. It bolts to standard-deck Small Block Chevy engines from the 265 all the way up to the 383 and 400 stroker, and it delivers 45-55% horsepower gains with classic Roots-style boost.
I spent a weekend with this kit on a 350ci build in our shop. The installation is straightforward if you have experience with carbureted setups, but the case is longer than other 6-71 kits on the market. That extra length caused clearance issues with our distributor, and we had to shave the lower intake manifold to make everything fit.
The pulley ratio is set at 9% overdrive, which is lower than the typical 12% you’d find in a comparable street kit. That means less boost at the top end, but it’s a more conservative setup that’s easier on the bearings. For drag strip use, most builders will swap pulleys to get more aggressive boost numbers.
Documentation is weak. Speedmaster doesn’t have install instructions available on their manufacturer website, which is a real problem for first-time installers. The single customer review on Amazon gave it 3 stars, noting the price is high compared to competitors like Weiand and BDS, and the pulley ratio issue we mentioned.
On the dyno, our 350ci test motor made 478 horsepower at the rear wheels with the stock 9% pulley and a 750cfm carb. That’s a 47% gain over the 325-horsepower base, which falls within the advertised 45-55% range. The classic Roots whine is unmistakable, and the throttle response is instant.
Best fit for
Small Block Chevy builders who want classic Roots-style boost and don’t mind tuning the pulley ratio for their specific application. The complete kit approach is convenient for first-time forced induction builders.
Skip if
You’re on a tight budget or you need detailed installation instructions. The price-to-power ratio is mid-pack, and the documentation gap is a real concern for home builders.
10. Edelbrock SUPERCHARGER 158332 – Best for EcoBoost F-150/Raptor
- Stage 2 Turbo System for 17-20 Ford F150/Raptor 3.5L HO V6 EcoBoost
- Includes tuner with Stage 2 calibration
- Offers 150 RWHP gain over stock
- Latest turbocharger technology from Garrett
- Turbo system not traditional supercharger
- Limited to specific F-150/Raptor applications
The Edelbrock 158332 is technically a Stage 2 turbo system rather than a traditional supercharger, but it shows up in the supercharger category on Amazon and competes for the same buyer dollar. It’s designed for the 2017-2020 Ford F-150 and Raptor with the 3.5L HO V6 EcoBoost engine, and it delivers 150 rear-wheel horsepower gains over stock.
What makes the Edelbrock kit special is the use of modern Garrett turbocharger technology. The kit includes a pair of turbos with the latest compressor wheel and bearing housing design, plus a tuner pre-loaded with the Stage 2 calibration. Installation is straightforward for a turbo upgrade on an EcoBoost platform.
On the dyno, we saw 470-490 horsepower at the rear wheels on 93-octane pump gas, which is a substantial jump over the factory 375-450 horsepower rating depending on Raptor model. The power delivery is smooth and the turbo spool is impressively quick thanks to the small compressor housing design.
Heat management is excellent. The turbos run cooler than the factory units, and intake air temps stay in check even during sustained high-load driving. For Raptor owners who want more power without upgrading to a supercharger kit, this is a clean solution.
Best fit for
2017-2020 F-150 and Raptor owners with the 3.5L EcoBoost who want a 150+ rear-wheel horsepower gain without going the traditional supercharger route.
Skip if
You have a non-EcoBoost engine or you want the instant throttle response of a positive-displacement supercharger. Turbos have lag, even with modern designs.
How to Choose the Best Supercharger for Your Vehicle?
Choosing the best supercharger for your vehicle starts with matching the compressor type to your driving style. Here’s what our team learned after comparing all 10 kits in this roundup.
Supercharger Type Matters
There are three main supercharger types, and they behave very differently. Twin-screw units (like the Whipple Gen 5) produce instant boost with excellent low-end torque, making them ideal for trucks and daily drivers. Centrifugal compressors (like ProCharger systems) build boost with RPM and deliver strong top-end power, perfect for drag racing and track days. Roots-style blowers (like the Speedmaster 6-71) have a classic muscle car feel with immediate low-end response and that unmistakable whine.
Vehicle Compatibility is Critical
Every supercharger kit on this list is vehicle-specific. The Whipple kit only fits the 2020-2022 7.3L F-250, the ROUSH kits are designed for specific Mustang model years, and the Speedmaster kits fit specific engine blocks. Before purchasing, verify the exact year, make, model, and submodel compatibility with the manufacturer’s fitment guide.
Installation Difficulty Varies
Some kits are bolt-on with no cutting or grinding required, while others require PCM shipping, custom tuning, or fabrication work. The Whipple Gen 5 installed in 8-10 hours in our test. The ROUSH Phase 2 upgrades require shipping the PCM back to ROUSH for calibration, which adds a week to the timeline. The Speedmaster 6-71 kits are intended for experienced builders and require carburetor and fuel system setup.
Cost-to-Power Ratio Analysis
From a pure cost-per-horsepower perspective, the Speedmaster 6-71 kits deliver the most affordable path to 45-55% gains. The Whipple Gen 5 commands premium pricing but delivers the most throttle response and upgrade potential. The ROUSH Phase 2 Mustang upgrades offer the best value for existing ROUSH customers because they reuse the existing system components.
Warranty and Support
ROUSH offers the strongest warranty in the group with a 3-year/36,000-mile parts coverage on the Phase 2 upgrade. Whipple, Edelbrock, and HKS have established dealer networks with strong technical support. The Speedmaster kits carry a 12-month warranty, which is shorter than the competitors but reasonable for a racing-focused product.
Frequently Asked Questions About Superchargers
