For Lexus RCF owners craving unparalleled power without sacrificing daily driving comfort and reliability, the RR780 Supercharger Kit emerges as the definitive solution. After rigorous development and testing spanning over a year, encompassing track days, desert trials, and over 10,000 miles of demanding use and meticulous tuning, we at obd2global.com are proud to present this transformative upgrade. Our objective was clear: to amplify the Lexus RCF’s horsepower to supercar levels while preserving the smooth drivability and unwavering reliability that define this exceptional vehicle.
RR780 Supercharger Kit: Engineered for Unrivaled Lexus RCF Horsepower
The RR780 kit is meticulously engineered to deliver a significant boost in Lexus Rcf Hp, transforming your driving experience. Let’s delve into the specifications that make this kit a game-changer:
Base RR780 Kit: Power and Performance Metrics
The foundation of our performance enhancement, the base “RR780” kit, is designed to elevate your Lexus RCF HP to impressive figures. Expect to achieve approximately 670 horsepower at the crank, translating to a robust 560 to 570 wheel horsepower (whp). These figures are measured on a Dynojet dyno, SAE corrected, utilizing 93 pump gas, and in conjunction with standard PPE Headers and a high-flow dual exhaust system. This power surge is achieved at a conservative 6psi peak boost pressure, highlighting the efficiency of our system.

Stage 1 Upgrade: Ethanol Enhanced Lexus RCF HP
For enthusiasts seeking even greater Lexus RCF HP, the Stage 1 upgrade unlocks further potential. By incorporating an ethanol kit and blending approximately 30% ethanol, you can anticipate reaching around 630whp. This translates to an astonishing 750 horsepower at the crank! To ensure precise fuel mixture, an ethanol content gauge is included in this upgrade. Alternatively, comparable Stage 1 power gains can be realized through the addition of a water/methanol injection system, offering flexibility in achieving your desired Lexus RCF HP.
Stage 4 Upgrade: Maximum Lexus RCF HP Unleashed
For those who demand the absolute pinnacle of Lexus RCF HP, the Stage 4 upgrade represents the ultimate transformation. Running on 100% ethanol, this upgrade is engineered to deliver approximately 700 whp. This comprehensive upgrade includes a smaller pulley to increase boost, a Stage 4 specific ECU tune, an ethanol kit, upgraded port injectors, and an uprated in-tank fuel pump. A water-methanol kit alternative is available for those preferring this route, targeting around 650 whp while maximizing Lexus RCF HP.
Precision Tuned ECU: The Brains Behind the Boosted Lexus RCF HP
Our commitment to reliability and drivability is underscored by the countless hours dedicated to perfecting our ECU tune for the Lexus RCF. We reject piggyback systems in favor of meticulously remapping the stock ECU. Literally hundreds of maps have been refined, and additional functionalities integrated into the fueling system. This sophisticated tuning allows us to reliably support up to 570whp without necessitating fuel system modifications in the base RR780 kit, ensuring optimized Lexus RCF HP delivery.
Rotrex Supercharger: The Heart of the Lexus RCF HP Upgrade
At the core of the RR780 kit lies the state-of-the-art Rotrex Supercharger, specifically the C38R model. Renowned for its efficiency and quiet operation, the Rotrex system utilizes a planetary drive, akin to a turbocharger, to deliver seamless and potent Lexus RCF HP gains.
Dedicated Drive System: Ensuring Reliable Lexus RCF HP Delivery
Unlike systems that rely on the accessory belt, we engineered a dedicated drive system for the supercharger. This crucial design element allows us to achieve optimal belt tension, essential for reliable supercharger operation and maximized Lexus RCF HP, without imposing undue stress on the alternator, water pump, and AC bearings.
Custom Harmonic Crank Damper: Protecting Your Lexus RCF Engine
Addressing a critical aspect often overlooked, we collaborated with ATI Performance to develop a custom-tuned harmonic damper. Many aftermarket supercharger kits for ISF/RCF models eliminate the factory harmonic damper, replacing it with a simple aluminum pulley – a compromise we deemed unacceptable. Our custom ATI damper is specifically engineered to dampen engine harmonics at elevated Lexus RCF HP levels, ensuring paramount engine reliability.

Billet Tensioner System: Robust and Reliable Lexus RCF HP
Elevating reliability further, we developed a billet belt tensioner system. Surpassing conventional OEM tensioners, our billet tensioner provides superior reliability and applies significantly higher belt tension, crucial for consistent Lexus RCF HP delivery. For added durability, we incorporate Gates Racing Kevlar drive belts and our proprietary double bearing billet idler pulleys.
Dual “Big Bubba” Billet Blow Off Valves: Responsive Lexus RCF HP
Responsiveness, reliability, and drivability are paramount. Therefore, the RR780 kit features not one, but two Turbosmart “Big Bubba” 2″ blow off valves. This ample venting capacity is essential for maintaining optimal supercharger performance and ensuring a responsive and enjoyable Lexus RCF HP experience.
Custom Air-to-Air Intercooler: Cooling for Maximum Lexus RCF HP
To manage the increased temperatures associated with boosted Lexus RCF HP, we employ a large, high-quality 4.5″x12″x10″ air-to-air intercooler core. Manufactured in the USA by Bell Intercoolers, these intercoolers are designed for maximum cooling efficiency, ensuring consistent and reliable Lexus RCF HP output.
Genuine Carbon Fiber Intake Tubing: Performance with Aesthetic Appeal
All visible intake tubing is crafted from genuine twill weave carbon fiber. This not only provides functional benefits but also adds an aesthetically striking element to your engine bay, complementing the enhanced Lexus RCF HP with visual appeal.
Model Year Compatibility: Expanding Lexus RCF HP to Newer Models
The RR780 Supercharger Kit is available for model years 2017-2019 and newer for an additional charge, broadening the reach of enhanced Lexus RCF HP to a wider range of vehicles. Please note that 2019+ models with Launch Control Option are not currently compatible.
Important Considerations for Optimizing Your Lexus RCF HP Upgrade
To ensure you maximize the benefits of your Lexus RCF HP upgrade, consider the following recommendations:
- Boost Gauge: A boost gauge is highly recommended to monitor your system’s performance. We offer a complete boost gauge kit as an optional addition.
- Air/Oil Separator (AOS): While not strictly required for the supercharger, we recommend our Air/Oil Separator (AOS) for enhanced engine longevity.
- Spark Plug Upgrade: A spark plug upgrade may be necessary. We recommend our Brisk Silver spark plugs for optimal performance with all our supercharger kits.
- ECU Exchange (2017+ Models): Model years 2017 and newer will require a 2016 ECU exchange for an additional charge.
