We are excited to announce that after over a year in development and testing, multiple track days, desert testing, and over 10,000 miles of punishment and tuning, we are finally ready to release our RC F/GS F Supercharger kit! Our goal for this kit was to maintain stock drivability and reliability, while creating smooth, seamless, and unrelenting supercar levels of power that these great car deserves.
RR670 Kit Specifications:
- Power: For the base "RR670" 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.
- Optional Power: With our optional Stage 1 ethanol kit, you can expect 638whp and 521wtrq. This translates into about 750hp at the crank! Stage 1 requires blending about 30% ethanol. With our Stage 2 kit, which includes and external sump and fuel pump, you will get a whooping 660whp or 770hp at the crank. Stage 2 also requires about 50% ethanol. Stage 3 get about 670whp and requires 70% ethanol blend. Please note that for new kits, Stage 1 through 3 will get the new C38R blower, while existing kits with C38-92 can use the existing blower with some limitations. Stage 4 upgrade runs only on C38R Rotrex blower, our methanol kit. Running on 100 octane race gas, Stage 4 is able to reach 700whp or 814hp at the crank!
- 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, c38-92 (largest Rotrex SC). Rotrex SC's are extremely efficient and quiet due to their planetary drive system which spins up to 90,000 rpm, 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 SC'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!
