Centrifugal superchargers deliver smooth, linear power, making the ISF incredibly responsive. The specific model may vary, but rest assured, it's chosen for its ability to deliver significant horsepower gains without sacrificing durability.
• Intercooler System: An air-to-air intercooler is crucial for keeping intake air temperatures (IATs) down. When air is compressed by the supercharger, it heats up, reducing its density and power potential. The intercooler cools this air, allowing for more efficient combustion and preventing detonation. RR Racing's intercooler system is designed for maximum cooling efficiency, ensuring consistent performance even under demanding conditions. This is essential for maintaining the longevity of your engine.
• Fuel Injectors: The stock fuel injectors simply can't supply enough fuel to support the increased airflow from the supercharger. Upgraded fuel injectors with a higher flow rate are included in the kit to ensure the engine receives the proper amount of fuel, preventing a lean condition that could lead to engine damage. These injectors are carefully chosen to match the supercharger's output and maintain optimal fuel atomization.
• ECU Tuning: The ECU is the brain of your car, and it needs to be reprogrammed to properly manage the supercharger system. RR Racing provides a pre-programmed ECU or tuning solution that optimizes the engine's parameters for the increased airflow and fuel delivery. This tuning ensures that the engine runs safely and efficiently, maximizing power output while maintaining reliability. Proper tuning is absolutely critical for the long-term health of your engine.
• Intake and Plumbing: The kit includes all the necessary intake tubes, hoses, and clamps to connect the supercharger to the engine's intake manifold and the intercooler. These components are designed for optimal airflow and durability, ensuring a secure and leak-free installation. RR Racing pays close attention to the design and materials used in these components to ensure they can withstand the increased pressure and temperature of the supercharged system.
