For Lexus RCF and GS F owners craving supercar performance without sacrificing daily drivability and reliability, the RR780 Supercharger Kit is engineered to deliver. After rigorous development, including track testing, desert trials, and over 10,000 miles of real-world punishment, this kit transforms your Lexus, injecting it with unrelenting power while maintaining the smooth and seamless driving experience you expect.
RR780 Kit: Precision Engineered for Maximum Lexus RCF HP
The base “RR780” kit is meticulously designed to elevate your Lexus Rcf Hp to impressive levels. Expect to see approximately 670hp at the crank, translating to 560 to 570whp (wheel horsepower on a Dynojet dyno, SAE corrected). This substantial power increase is achieved at a conservative 6psi peak boost pressure, utilizing readily available 93 pump gas, and when paired with standard PPE Headers and a high flow dual exhaust system. For those seeking even greater Lexus RCF HP, we offer staged upgrade paths:
-
Stage 1 Upgrade: Ethanol or Water/Methanol Injection for Enhanced Lexus RCF HP
Opting for the Stage 1 upgrade, incorporating an ethanol kit, can push your Lexus RCF HP to around 630whp. This translates to an astonishing 750hp at the crank! Stage 1 necessitates a blend of approximately 30% ethanol fuel. To ensure accurate fuel mixture, an ethanol content gauge is included. Alternatively, similar Stage 1 power gains can be achieved through water/methanol injection, offering flexibility in your performance enhancement strategy. -
Stage 4 Upgrade: Unleashing Extreme Lexus RCF HP with 100% Ethanol
For the ultimate pursuit of Lexus RCF HP, the Stage 4 upgrade is engineered for 100% ethanol fuel. This aggressive configuration can yield approximately 700 whp. The Stage 4 package includes a smaller supercharger pulley to increase boost, a specialized Stage 4 ECU tune, an ethanol kit, upgraded port injectors, and an upgraded in-tank fuel pump. A water-methanol kit alternative is also available for Stage 4, delivering around 650 whp for those preferring this route.
The Heart of the Kit: Rotrex Supercharger and Advanced Components
At the core of the RR780 kit lies the Rotrex Supercharger, specifically the C38R model. Renowned for its efficiency and quiet operation, Rotrex superchargers employ a planetary drive system, similar to turbochargers, ensuring smooth and reliable power delivery. Beyond the supercharger itself, the RR780 kit incorporates a suite of premium components designed for optimal performance and longevity:
-
Dedicated Drive System: Unlike kits that rely on the accessory belt, our dedicated drive system ensures consistent and reliable supercharger operation. This design allows for precise belt tensioning, preventing stress on ancillary components such as the alternator, water pump, and AC bearings.
-
Custom Harmonic Crank Damper: Addressing a critical aspect often overlooked, we collaborated with ATI Performance to develop a custom-tuned harmonic damper. This crucial component replaces inferior aluminum pulleys found in some aftermarket kits and is specifically engineered to dampen engine harmonics at high Lexus RCF HP levels. This ensures unparalleled engine reliability and longevity.
-
Billet Tensioner System: While many kits utilize standard OEM tensioners, we’ve elevated durability with a billet belt tensioner. This robust tensioner provides superior reliability and applies significantly higher belt tension compared to off-the-shelf alternatives. Complementing this, we incorporate Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys, ensuring a drive system built to withstand extreme Lexus RCF HP demands.
-
Dual “Big Bubba” Billet Blow Off Valves: Responsiveness and reliability are paramount. That’s why the RR780 kit features two Turbosmart “Big Bubba” 2″ blow off valves. This dual valve setup ensures adequate venting, crucial for supercharger responsiveness, long-term reliability, and seamless drivability, especially in high Lexus RCF HP configurations.
-
Custom Air/Air Intercooler: Managing intake temperatures is vital for sustained performance. Our kit utilizes a large 4.5″x12″x10″ air-to-air intercooler core, manufactured in the USA by Bell Intercoolers. These intercoolers are recognized for their exceptional quality and cooling efficiency, essential for maintaining optimal Lexus RCF HP output under demanding conditions.
-
Genuine Carbon Fiber Intake Tubing: Beyond performance, aesthetics matter. All visible intake tubing is crafted from genuine twill weave carbon fiber. This not only enhances the visual appeal of your engine bay but also provides lightweight and rigid intake pathways.
-
Wide Model Year Compatibility: The RR780 Supercharger Kit is available for Lexus RCF models from 2017-2019 and newer, with compatibility for 2019+ models with Launch Control currently under development. Please inquire about compatibility for your specific model year.
Essential Considerations for Your Lexus RCF HP Upgrade
To maximize your experience and ensure optimal performance and monitoring of your enhanced Lexus RCF HP, we recommend the following additions:
-
Boost Gauge: A boost gauge is highly recommended to monitor supercharger performance. We offer a complete boost gauge kit as an optional addition (available in our Gauges category).
-
Air/Oil Separator (AOS): While not strictly required for supercharger operation, we strongly recommend our Air/Oil Separator (AOS) to further enhance engine longevity, especially at increased Lexus RCF HP levels.
-
Spark Plug Upgrade: Depending on your specific setup and desired Lexus RCF HP, a spark plug upgrade may be necessary. We recommend Brisk Silver spark plugs for optimal performance with our supercharger kits.
-
ECU Exchange for 2017+ Models: Lexus RCF models from 2017 and onwards will require a 2016 ECU exchange for an additional charge to ensure proper system integration and tuning.
