Supercharging a modern Lexus is nothing new here at RR Racing. In fact, we are officially at the 10 year anniversary of the world's first Supercharged ISF. Since then we have successfully supercharged hundreds of ISF's, GSF's and RCF's. Although horsepower drives us to do this, we weigh reliably as a main factor in our product offerings. That's why all of our kits have been extensively track tested to ensure the highest level of reliability before releasing to the customer. Our Supercharged RCF Shop car (The Red Devil seen on Youtube) has been supercharged since 2017 and has participated in over 50+ Track days, all on the OEM engine and transmission!

We are now officially offering our very own RR780 for the 2022+ IS500. this is a complete build that will transform your IS500 into a 670+HP MONSTER! In order to participate in an IS500 build, you must be local to our shop in Phoenixville PA, within a reasonable distance, or willing to transport the car in.

Choose from the Following:

Base Stage 1 supercharger build includes the following

• RR780 Supercharger complete kit
• Innovate Boost AFR Gauge
• Brisk 1 step Colder spark plugs
• Complete installation and custom dyno tuning.

Stage 2 option is everything above and includes

• PPE UEL headers w/ ceramic coating (necessary for Supercharging)

- A base SC build running on 93 octane will make aprx 575 wheel hp. Email us about options for Stage 4 upgrades to make 630 - 700+ Wheel HP!

RR780 Kit Specifications:

• Power: For the base "RR780" kit, our customers can expect to make about 670hp at the crank, or 560 to 570whp (wheel horsepower on a Dynojet dyno, SAE correction -- see dyno result chart below and in the product photos gallery) at approximately 6psi peak boost pressure, 93 pump gas, equipped with standard PPE Headers and a high flow dual exhaust.
• Tuned ECU: We have logged countless development hours perfecting our ECU tune for the RC F for ultimate reliability and drivability. No piggybacks or other BS! We have extensively developed the mapping of the stock ECU, modifying literally hundreds of maps and adding additional functionality to the fueling system that allows us to support up to 570whp without fuel system modifications.
• Supercharger: Rotrex Supercharger, C38R (the most advanced Rotrex S/C system). Rotrex S/C's are extremely efficient and quiet due to their planetary drive system much like a turbocharger.
• Dedicated Drive System: Rather than using the accessory belt to drive the SC, we designed a dedicated drive system that allows us to achieve the necessary belt tension for a reliable SC drive, without overstressing the alternator, water pump, and AC bearings.
• Custom Harmonic Crank Damper: There are some overpriced Japanese S/C's on the market for the ISF/RCF that eliminate the factory harmonic damper crank pulley and replace it with a simple machined aluminum pulley. We find this simply unacceptable! Working in conjunction with ATI Performance, we developed a custom tuned harmonic damper than drives the SC belt. The ATI damper has been specially developed to dampen the harmonics of the 2UR-GSE engine at high horsepower levels for the ultimate in engine reliability.
• Billet Tensioner System: Most SC kits on the market use OEM belt tensioners, but we took that a step further by developing a billet belt tensioner that is both more reliable and is able to apply significantly higher belt tension than conventional off the shelf tensioners. For added reliability we use Gates Racing Kevlar drive belts and our own double bearing billet idler pulleys.
• Dual "Big Bubba" Billet Blow Off Valves: We use not one, but TWO Turbosmart "Big Bubba" 2" blow off valves. Adequate venting is essential for SC responsiveness, reliability, and drivability.
• Custom Air/Air Intercooler: We use a large 4.5"x12"x10" intercooler core. These intercoolers are extremely high quality and are manufactured in the USA by Bell Intercoolers.
• Genuine Carbon Fiber Intake Tubing: All visible intake tubing is made from genuine twill weave carbon fiber for an amazing look and function!
• Stage 4 Upgrade: running 100% ethanol for about 700+ whp. Includes smaller pulley, Stage 4 tune, ethanol kit, upgraded port injectors and upgraded in-tank fuel pump. This upgrade is also available with a water-methanol kit for about 650 whp.

Please consider the following:

• We also recommend buying our Air/Oil Separator (AOS) -- although not required for the supercharger.

Please refer to the dyno charts in the photo catalog of this product.
