1. Vortech V-3 Si Trim Supercharger Kit: Best Overall
The Vortech V-3 Si Trim is a top-tier centrifugal supercharger that delivers impressive power gains without compromising reliability. Based on owner feedback and the spec sheets, this kit consistently produces over 600 wheel horsepower on a stock LS2 with a safe tune. The self-contained oil system is a major plus, as it eliminates the need to tap into the engine’s oil supply, reducing installation complexity and potential leak points.
However, the kit’s price point is on the higher side, and installation can be time-consuming for those without experience. It also requires a custom tune, which may add to the overall cost. If you’re looking for a simpler bolt-on solution, this might not be the best choice, but for enthusiasts seeking maximum power and reliability, it’s hard to beat.
- Proven 600+ hp on stock LS2 with safe tuning
- Self-contained oil system eliminates engine oil tapping
- Comprehensive kit includes intercooler, injectors, and tune
Pros: Excellent power gains with linear delivery; High-quality cast aluminum construction
Cons: Installation requires moderate mechanical skill
2. ProCharger P-1SC-1 Supercharger Kit: Best Value
The ProCharger P-1SC-1 offers an outstanding balance of performance and cost. We compared it against other kits in its class, and it delivers reliable power gains of around 500-550 wheel horsepower on a stock LS2. The self-contained oil system and helical gear design make it quieter and easier to install than many competitors. Owner feedback highlights its consistent performance and durability over time.
One limitation is that the base kit does not include an intercooler, which is recommended for sustained high-performance use. Adding an intercooler increases the overall cost but is a worthwhile investment for those planning to push the car hard. If you’re on a tighter budget and can live with an uncooled setup for occasional use, this is a solid choice.
- Excellent power-to-price ratio
- Self-contained oil system for easy installation
- Quiet operation with helical gears
Pros: Great value for the power output; Polished finish looks great under the hood
Cons: Intercooler not included in base kit
3. Magnuson TVS1900 Supercharger Kit: Best Roots-Type
The Magnuson TVS1900 is a roots-type supercharger that provides immediate boost and strong low-end torque, making it ideal for street-driven LS2 vehicles. We evaluated it based on manufacturer specs and owner reports, and it consistently delivers a fun, responsive driving experience. The integrated intercooler helps maintain intake air temperatures, and the CARB EO number ensures legality in all states.
However, the kit is heavier than centrifugal options, which can affect front-end weight distribution. It also generates more heat under sustained high-rpm use, though the intercooler mitigates this. If you primarily drag race or track your car, a centrifugal might be a better fit. For daily driving and street performance, this is a top contender.
- Instant throttle response with low-end torque
- Integrated intercooler for consistent performance
- CARB approved for street use in all 50 states
Pros: Excellent low-end torque for street driving; CARB legal, no smog issues
Cons: Heavier than centrifugal alternatives
4. Whipple W175AX Supercharger Kit: High Power Choice
The Whipple W175AX is designed for those who want the highest possible power output from their LS2. Based on our research and owner feedback, this kit can support over 700 wheel horsepower with proper supporting modifications. The large intercooler and included fuel system components make it a comprehensive package for serious builds. The twin-screw design provides strong mid-range torque and excellent throttle response.
That said, the kit is expensive and requires a significant financial investment. Installation is more complex due to the larger intercooler and fuel system upgrades. It’s also not ideal for stock engines, as the boost levels may exceed their safe limits. If you’re building a fully forged engine and chasing big numbers, this is an excellent choice; otherwise, it may be overkill.
- Capable of 700+ horsepower with supporting mods
- Large intercooler core for excellent heat management
- Includes high-flow injectors and fuel pump
Pros: Extreme power potential; High-quality construction and finish
Cons: Premium price point
5. Edelbrock E-Force Supercharger Kit: Easiest Install
The Edelbrock E-Force is the easiest supercharger kit to install on an LS2, based on our comparison of instructions and owner experiences. It comes pre-assembled and includes a custom tune and injectors, so you can install it in a weekend. The roots-type design provides good low-end torque, and the CARB approval makes it hassle-free for street use.
However, the power gains are conservative compared to other kits, typically around 450-500 wheel horsepower. This is due to the lower boost levels and smaller intercooler. If you’re looking for big power, this may not satisfy you. But for a daily driver that just wants a reliable boost in performance with minimal fuss, it’s an excellent option.
- Designed for easy DIY installation with clear instructions
- Includes a custom tune and injectors for plug-and-play
- CARB legal and 50-state smog compliant
Pros: Simplest installation of all kits reviewed; Comes complete with tune and injectors
Cons: Modest power gains compared to competitors
6. A&A Corvette Supercharger Kit: Corvette Specific
The A&A Corvette Supercharger Kit is tailored for LS2-powered Corvettes, ensuring a perfect fit and straightforward installation. We researched owner feedback and found that it delivers reliable power gains of around 550 wheel horsepower. The self-contained oil system and included brackets make it a clean install. It’s a popular choice among Corvette enthusiasts for its performance and ease of installation.
However, this kit is not designed for other LS2 applications like trucks or sedans, which limits its versatility. Additionally, the price is on the higher side for the power level. If you own a Corvette and want a proven, bolt-on solution, this is a great pick. For other vehicles, look elsewhere.
- Specifically designed for Corvette LS2 fitment
- Self-contained oil system for clean installation
- Includes all necessary brackets and hardware
Pros: Perfect fit for Corvette C6 LS2; Good power gains with linear delivery
Cons: Limited to Corvette applications
7. Lingenfelter LS2 Supercharger Kit: Premium Build
The Lingenfelter LS2 Supercharger Kit is a premium offering from a renowned builder. We compared it to other kits and found that its hand-assembled components and thorough testing result in a very reliable system. It includes an intercooler and fuel system upgrades, making it capable of supporting 600+ horsepower safely. Owner feedback praises the quality and the support from Lingenfelter.
However, this kit comes at a premium price that is significantly higher than comparable options. The power gains are not substantially better than more affordable kits. If you have a generous budget and value exclusivity and top-tier support, this is a solid choice. For most buyers, the cost is hard to justify given the availability of excellent alternatives.
- Hand-assembled and tested by Lingenfelter
- Includes intercooler and fuel system for reliability
- Known for high-quality components and support
Pros: Exceptional build quality and attention to detail; Excellent customer support from Lingenfelter
Cons: Very expensive, not for budget builds
Frequently Asked Questions
What is the best supercharger for a stock LS2 engine?
For a stock LS2, we recommend the Vortech V-3 Si Trim or the Edelbrock E-Force. The Vortech offers more power potential with safe tuning, while the Edelbrock is easier to install and CARB legal. Both are reliable choices that won’t exceed the engine’s limits.
Do I need to upgrade my fuel system with a supercharger?
Most supercharger kits include fuel system upgrades like larger injectors and a higher-flow fuel pump. For kits that don’t, such as the base ProCharger P-1SC-1, we recommend adding an upgraded fuel pump and injectors to ensure safe operation, especially at higher boost levels.
Can I install a supercharger myself?
Installation difficulty varies. Kits like the Edelbrock E-Force and Vortech V-3 are designed for DIY installation with clear instructions. More complex kits like the Whipple W175AX may require professional installation. We recommend having mechanical experience or a trusted shop for best results.
Are these supercharger kits CARB legal?
Only the Magnuson TVS1900 and Edelbrock E-Force have CARB EO numbers, making them legal in all 50 states. Other kits may not be smog-compliant in California and some other states. Always check local regulations before purchasing.
What is the maintenance required for a supercharger?
Centrifugal superchargers with self-contained oil systems require periodic oil changes (typically every 20,000-30,000 miles). Roots-type superchargers like the Magnuson and Edelbrock have sealed bearings and require no regular maintenance. Always follow the manufacturer’s recommendations.
Our Verdict
After researching and comparing these supercharger kits for the 6.0L LS2, our top pick is the Vortech V-3 Si Trim for its excellent power gains, reliability, and self-contained oil system. The runner-up is the ProCharger P-1SC-1, offering great value and performance for budget-conscious builders. Both are proven choices that will satisfy most enthusiasts.
