Unleash Beastly Lexus RCF HP with the RR780 Supercharger Kit

The Lexus RCF is a masterpiece of engineering, blending luxury with exhilarating performance. But for those who crave even more power, the untapped potential of the 2UR-GSE engine is ripe for the taking. After rigorous development and testing spanning over a year, including punishing track days and desert trials, we at cardiagnosticnearme.com are thrilled to introduce the RR780 Supercharger Kit for Lexus RCF and GSF. Our mission was clear: to amplify the Lexus Rcf Hp to supercar levels without compromising the refined drivability and rock-solid reliability you expect.

RR780 Supercharger Kit: Elevating Lexus RCF HP to New Heights

This isn’t just about adding raw power; it’s about crafting a seamless and breathtaking surge of performance that complements the Lexus RCF’s inherent character. The RR780 kit is meticulously engineered to deliver a substantial increase in Lexus RCF HP, transforming your already impressive machine into a true powerhouse.

Power and Performance Specifications

The heart of the RR780 kit lies in its ability to dramatically increase Lexus RCF HP. Here’s a breakdown of what you can expect:

Base RR780 Kit: Expect a formidable 670 horsepower at the crank, translating to an impressive 560-570 wheel horsepower (whp) on a Dynojet dyno (SAE corrected). This is achieved at a conservative 6psi peak boost pressure, running on readily available 93 pump gas, and assumes the vehicle is equipped with standard PPE Headers and a high-flow dual exhaust system. (See dyno result chart below and in the product photos gallery for visual confirmation of these gains.)

Stage 1 Upgrade (Ethanol or Water/Methanol Injection): For enthusiasts seeking even greater Lexus RCF HP, the Stage 1 upgrade unlocks approximately 630whp. This translates to an astounding 750 horsepower at the crank! This upgrade can be achieved through either:
- Ethanol Blend: Requires blending approximately 30% ethanol fuel. An ethanol content gauge is included in the kit for precise fuel mixture management.
- Water/Methanol Injection: Provides similar Stage 1 power output as the ethanol blend option.
Stage 4 Upgrade (100% Ethanol or Water/Methanol Injection): For the ultimate pursuit of Lexus RCF HP, the Stage 4 upgrade, running on 100% ethanol, delivers around 700 whp. This comprehensive upgrade includes:
- Smaller supercharger pulley for increased boost.
- Stage 4 ECU tune optimized for high-ethanol fuel.
- Ethanol kit for seamless ethanol fuel delivery.
- Upgraded port fuel injectors to handle the increased fuel demand.
- Upgraded in-tank fuel pump to ensure consistent fuel supply.
A water-methanol injection variant of the Stage 4 upgrade is also available, delivering approximately 650 whp.

Advanced Supercharger System

At the core of the RR780 kit is the state-of-the-art Rotrex Supercharger, specifically the C38R model. Rotrex superchargers are renowned for their exceptional efficiency and quiet operation, thanks to their innovative planetary drive system, a design principle similar to turbochargers. This advanced supercharger technology is crucial for delivering smooth, linear power and maximizing Lexus RCF HP gains.

Dedicated Drive and Harmonic Damper

Dedicated Drive System: Unlike less sophisticated kits that rely on the accessory belt, our RR780 kit features a dedicated drive system. This meticulously engineered system ensures optimal belt tension for reliable supercharger operation without imposing undue stress on the alternator, water pump, and AC bearings. This dedicated system is paramount for long-term reliability and consistent Lexus RCF HP delivery.
Custom Harmonic Crank Damper: We understand the critical role of harmonic damping in high-performance engines. Rejecting the shortcut of replacing the factory damper with a simple aluminum pulley (as seen in some overpriced kits), we collaborated with ATI Performance to develop a custom-tuned harmonic damper. This ATI damper is specifically engineered to mitigate the harmonic vibrations of the 2UR-GSE engine at elevated horsepower levels, ensuring unparalleled engine reliability and longevity while pushing the boundaries of Lexus RCF HP.

Enhanced Components for Uncompromising Performance

Billet Tensioner System: While many supercharger kits utilize off-the-shelf OEM belt tensioners, we’ve gone above and beyond by developing a billet belt tensioner. This robust tensioner provides superior reliability and applies significantly higher belt tension compared to conventional tensioners. For added durability, we incorporate Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys, ensuring maximum power transfer and minimizing belt slip, crucial for consistent Lexus RCF HP.
Dual “Big Bubba” Billet Blow Off Valves: To ensure optimal supercharger responsiveness, reliability, and drivability, the RR780 kit employs two Turbosmart “Big Bubba” 2″ blow off valves. This dual-valve setup provides ample venting capacity, critical for maintaining boost pressure and preventing compressor surge, especially during rapid throttle changes when maximizing Lexus RCF HP.
Custom Air/Air Intercooler: Managing intake air temperature is paramount for maximizing power and engine longevity. The RR780 kit features a large, high-efficiency 4.5″x12″x10″ air-to-air intercooler core. These premium intercoolers are proudly manufactured in the USA by Bell Intercoolers, ensuring exceptional quality and cooling performance, vital for sustained high Lexus RCF HP output.
Genuine Carbon Fiber Intake Tubing: Beyond performance, aesthetics matter. All visible intake tubing in the RR780 kit is crafted from genuine twill weave carbon fiber. This not only provides a stunning visual upgrade under the hood but also offers functional benefits with its lightweight and heat-insulating properties.

Important Considerations

Boost Gauge Recommendation: To monitor your system’s performance, we highly recommend installing a boost gauge. 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 necessary for the supercharger system itself, we recommend considering our Air/Oil Separator (AOS) for enhanced engine health and reduced oil consumption, particularly under high-performance driving conditions associated with increased Lexus RCF HP.
Spark Plug Upgrade: Depending on your specific vehicle and driving style, a spark plug upgrade may be necessary. We recommend our Brisk Silver spark plugs for optimal performance and reliability with all our supercharger kits.
ECU Compatibility (Model Years 2017+): Please note that for model years 2017 and newer, a 2016 ECU exchange may be required for compatibility, incurring an additional charge. Currently, the 2019+ models with Launch Control Option are not compatible.
