After rigorous testing spanning six months, five track days, demanding desert trials, and over 9000 miles of intensive tuning and evaluation, we at cardiagnostictool.store are thrilled to introduce the revolutionary IS-F Supercharger kit. Our unwavering objective was to engineer a kit that not only elevates your Lexus IS-F to supercar power levels but also preserves the refined drivability and inherent reliability you expect from a luxury performance vehicle. Achieving seamless power delivery and unparalleled performance, all while leveraging the sophisticated 2ur gse stock ecu, has been at the heart of our development process.
RR780 Supercharger Kit: Precision Engineered for the 2UR-GSE Engine
This isn’t just about bolting on a supercharger; it’s about a holistic performance enhancement meticulously designed around the iconic 2UR-GSE engine and its factory ECU. Let’s delve into the specifications that define the RR780 Kit:
Power Redefined: Stage-Based Performance Upgrades
- Base Kit Performance: Expect a significant power jump to approximately 625 horsepower at the crank, translating to an impressive 530-550whp (wheel horsepower, Dynojet dyno, STD Smoothing 5). This is achieved at a conservative 7psi peak boost pressure on readily available 93 pump gas, assuming standard PPE headers and a 2.5” dual exhaust system.
- Stage 1 Upgrade: For enthusiasts craving even more, our Stage 1 kit and ECU recalibration pushes the boundaries further, delivering around 570whp, equating to approximately 670 horsepower at the engine. Consult the dyno chart in our product catalog for a visual representation of these gains.
- Stage 4 “RR780” Beast Mode: For the ultimate power enthusiast, the Stage 4 “RR780” upgrade unlocks a staggering 714whp, reaching an astounding 860 horsepower at the crank – a record-breaking achievement surpassing our previous 780hp benchmark! Detailed information on the Stage 4 upgrade is available under the ISF Power Upgrades category on our website.
Harnessing the 2UR-GSE Stock ECU for Superior Tuning
At RR Racing, we believe in maximizing the potential of the factory ECU. We’ve dedicated countless hours to perfecting our ECU tune specifically for the IS-F. This extensive development ensures not only exhilarating performance but also unwavering reliability and smooth drivability. Forget piggyback systems or unreliable workarounds. We delve deep into the 2ur gse stock ecu mapping, meticulously modifying hundreds of parameters and augmenting the fueling system’s capabilities. This allows us to reliably support up to 550whp without requiring any modifications to the stock fuel system in the base configuration. Our expertise in ECU tuning is paramount to seamlessly integrating this supercharger system with your vehicle’s existing electronics.
Key Components: Engineering Excellence in Every Detail
- Rotrex Supercharger (C38R): At the heart of our kit lies the Rotrex C38R supercharger, renowned for being the most advanced system in the Rotrex lineup. Rotrex superchargers are celebrated for their exceptional efficiency and remarkably quiet operation, attributes stemming from their sophisticated planetary drive system, a characteristic they share with turbochargers.
- Autonomous Dry Sump Supercharger Oiling System with Oil Cooler: Our kit incorporates a self-contained dry sump oiling system complete with its own dedicated oil cooler. This ingenious design eliminates the need to tap into the engine’s oil lines or introduce additional heat load into the engine’s cooling system, simplifying installation and enhancing thermal management.
- Dedicated Supercharger Drive System: Unlike systems that rely on the accessory belt, we engineered a dedicated drive system for the supercharger. This critical design choice allows us to achieve the precise belt tension required for reliable supercharger operation without imposing undue stress on the alternator, water pump, and AC bearings, ensuring long-term durability of all components.
- Custom Harmonic Crank Damper by ATI Performance: We reject the shortcut of replacing the factory harmonic damper with a simple aluminum pulley, a practice seen in some less sophisticated Japanese supercharger kits for the IS-F/RCF. Instead, we partnered with ATI Performance to develop a bespoke, tuned harmonic damper. This custom ATI damper is specifically engineered to effectively dampen the unique harmonics of the high-horsepower 2UR-GSE engine, providing unparalleled engine reliability and longevity.
- Billet Tensioner System: While many supercharger kits utilize off-the-shelf OEM belt tensioners, we go above and beyond with a custom-designed billet belt tensioner. This robust tensioner offers superior reliability and applies significantly higher belt tension compared to conventional options. For added assurance, we utilize Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys, ensuring maximum durability and performance under extreme conditions.
- Dual “Big Bubba” Billet Blow Off Valves by Turbosmart: To ensure optimal responsiveness, reliability, and drivability, we incorporate not one, but TWO Turbosmart “Big Bubba” 2″ blow off valves. Adequate venting is crucial for supercharged applications, and our dual valve system provides ample capacity for rapid pressure release.
- Custom Air-to-Air Intercooler by Bell Intercoolers: Cooling is paramount for maximizing power and efficiency. Our kit features a large 4.5″x12″x10″ intercooler core, meticulously manufactured in the USA by Bell Intercoolers, renowned for their exceptional quality and performance.
- Genuine Carbon Fiber Intake Tubing: Aesthetics matter. All visible intake tubing is crafted from genuine twill weave carbon fiber, delivering a stunning visual enhancement to your engine bay while maintaining functional performance.
Important Considerations Before Installation
- Boost Gauge Recommendation: We strongly recommend installing a boost gauge to monitor your supercharger system’s performance. We offer a complete boost gauge kit as an optional add-on, available in our Gauges category.
- Air/Oil Separator (AOS) Recommendation: While not strictly mandatory for the supercharger system itself, we highly recommend considering our Air/Oil Separator (AOS) for enhanced engine health and longevity. Please inform us if you do not have an AOS installed.
- Bumper Rail Modification: Installation necessitates the removal of the bumper rail to accommodate the intercooler. However, it is possible to retain portions of the rail on both sides, creating an opening specifically for the intercooler, preserving some structural integrity.
Ordering and ECU Recalibration
Customers who have previously purchased an OBD tune from us are eligible for a credit towards this supercharger kit. Please select the “Recalibration option” and indicate “Own Tune” during the ordering process. It is also essential to specify your IS-F model year by selecting the appropriate option to ensure correct ECU calibration files are provided.
