The 2008 Lexus IS F marked a turning point for Lexus, showcasing their commitment to performance. But what if you crave even more power? After rigorous testing and development, RR Racing proudly presents a supercharger kit designed to elevate your 2008 Lexus F Sport to supercar levels of performance while maintaining everyday drivability and reliability.
RR780 Supercharger Kit: Power and Refinement for Your Lexus
This comprehensive kit transforms your IS F, delivering exhilarating power and a refined driving experience. Here’s a detailed look at what sets the RR780 apart:
Unrivaled Power Gains
The base kit boosts your 2008 Lexus F Sport to approximately 530-550 wheel horsepower (whp) on a Dynojet dyno with standard PPE headers and a 2.5″ dual exhaust. This translates to roughly 625 horsepower at the crank, achieved with a peak boost pressure of 7 psi on 93 octane pump gas.
For those seeking even more, the Stage 1 kit and tune bump power up to 570 whp (approximately 670 hp). The ultimate upgrade, Stage 4 “RR780”, unleashes a staggering 714 whp (860 hp), setting a new benchmark for IS F performance. (For detailed Stage 4 information, explore the IS F Power Upgrades category.)
Precision Tuning and Key Components
-
Tuned ECU: Forget piggyback systems. RR Racing meticulously developed a custom ECU tune, optimizing hundreds of maps and enhancing the fueling system to support up to 550 whp without requiring fuel system modifications. This ensures seamless integration and optimal performance.
-
Rotrex C38R Supercharger: This cutting-edge supercharger utilizes a planetary drive system, similar to a turbocharger, delivering exceptional efficiency and quiet operation.
-
Independent Oiling and Drive Systems: A dedicated dry sump oiling system with an oil cooler ensures optimal lubrication without impacting the engine’s cooling system. A separate drive system maintains proper belt tension for reliable supercharger operation without stressing other engine components.
-
Engine Reliability Enhancements: A custom harmonic crank damper, developed in collaboration with ATI Performance, safeguards engine reliability at high horsepower levels. A billet tensioner system, Gates Racing Kevlar drive belts, and double bearing billet idler pulleys further enhance durability.
-
Enhanced Responsiveness and Cooling: Dual Turbosmart “Big Bubba” blow-off valves ensure optimal responsiveness and drivability. A large Bell Intercoolers air-to-air intercooler keeps intake temperatures in check.
-
Premium Materials: Genuine carbon fiber intake tubing not only looks fantastic but also improves airflow.
Important Considerations for Your 2008 Lexus F Sport
While this kit dramatically enhances performance, a few considerations are essential:
- Boost Gauge: Monitoring boost pressure is crucial. RR Racing offers a comprehensive boost gauge kit.
- Air/Oil Separator (AOS): Although not mandatory, an AOS is recommended.
- Bumper Rail Modification: Intercooler installation requires removing or modifying the bumper rail.
Ordering and Disclaimer
Previous purchasers of RR Racing’s OBD tune are eligible for a recalibration credit. When ordering, specify your IS F’s model year.
Disclaimer: This modification may void manufacturer warranties. RR Racing provides no warranty for the engine or drivetrain and recommends a thorough engine inspection before installation.
