What is the specs of the LX 570 supercharger?
There is no factory LX 570 supercharger. The LX 570 uses a naturally aspirated 5.7-liter V8 that outputs about 383 horsepower and 403 lb-ft of torque in most US-spec models. Any supercharger for the LX 570 comes from aftermarket suppliers, and its exact specifications depend on the kit and tune chosen.
As of today, Lexus discontinued the LX 570 in favor of the LX 600 in many markets, shifting the lineup away from the old V8 toward a newer powertrain. This article explains what “LX 570 supercharger” means in practice, what a typical aftermarket kit includes, the kind of performance gains you can expect, and the considerations involved in such a modification.
Factory status and engine basics
The LX 570 is powered by a 5.7-liter V8 paired with an automatic transmission. In most model years, it delivers roughly 383 horsepower and 403 lb-ft of torque in standard trim. There is no official Lexus-supplied supercharger option for the LX 570, meaning any forced induction is performed through third-party aftermarket kits rather than a factory specification from Toyota/Lexus.
Aftermarket supercharger options for the LX 570
What a typical LX 570 supercharger kit includes varies by supplier and model year, but most complete systems share several core components and supporting upgrades:
- Blower unit (Roots- or screw-type positive-displacement or centrifugal design) sized for a 5.7L V8
- Intercooler or aftercooler to reduce intake air temperature
- New intake plumbing and blower-specific throttle-body or intake manifold
- Drive belt, pulleys, and tensioning hardware
- Fuel system upgrades (higher-flow injectors, a higher-capacity/in-tank fuel pump, and possibly a fuel pressure regulator)
- Engine management recalibration (ECU/OCU tune) to accommodate boost and altered fueling
- Upgraded cooling components (radiator, and often an auxiliary oil or transmission cooler)
- Optional exhaust enhancements to complement increased airflow
Conclusion: Kits differ by vendor, year, and intended use (daily driver vs. performance-focused). Always verify compatibility with your LX 570’s specific model year and transmission, and consult a qualified technician before purchasing or installing a system.
Performance expectations and considerations
Understanding what a supercharger does for an LX 570 requires recognizing that gains depend on the kit, tune, and supporting hardware. Here is a general guide to what owners can expect and what to consider before moving ahead:
- Boost pressure typically targets a modest level for daily driving, commonly in the 6–8 psi range, though some setups push higher with upgraded intercooling and cooling capacity.
- Estimated crank horsepower gains generally run in the ballpark of 100–150+ hp, with torque increases often in the 100–200 lb-ft range—again, highly kit-dependent.
- Fuel system requirements: upgraded injectors and a stronger fuel pump are common to maintain safe air/fuel ratios under boost; high-octane fuel is often recommended.
- Cooling and reliability: enhanced intercooling and oil/engine cooling are important to maintain performance and prevent heat-related issues on a boosted V8.
- Drivetrain and transmission considerations: power gains must be matched with compatible transmission tuning and, in some cases, reinforcing components or software changes to handle higher torque and altered shift points.
- Warranty, legality, and insurance: aftermarket forced induction can affect warranty coverage and may require emissions or registration considerations depending on the region.
- Installation and cost: projects are typically multi-day installs by specialists, with kit costs plus professional labor often running into several thousand dollars.
Conclusion: Real-world results vary widely. A carefully selected kit with proper tuning and supporting upgrades can deliver meaningful performance increases, but buyers should weigh cost, reliability, warranty, and emissions considerations.
Summary
The LX 570 did not come with a factory supercharger; any supercharger setup is aftermarket and year/model dependent. The stock SUV runs a 5.7L V8 with roughly 383 hp and 403 lb-ft of torque. Aftermarket kits provide a blower, intercooler, fuel and ECU upgrades, and cooling enhancements, with typical gains of about 100–150 hp and 100–200 lb-ft of torque—subject to the kit, tuning, and supporting hardware. If pursuing forced induction, work with a qualified tuner, verify compatibility for your specific LX 570 year, and consider warranty, emissions, and long-term reliability.
