V-3 H67B Centrifugal Supercharger System

The Vortech Complete V-3 H67B Supercharger System is engineered to significantly enhance the performance of the 2013-2021 Subaru BRZ and 2013-2020 Scion FR-S. This comprehensive kit provides a substantial power increase, achieving an estimated 294 horsepower and 210 lb-ft of torque with 9 PSI of boost at the factory redline, all while utilizing 91-octane fuel. The system includes a replacement MAP sensor and an Ecutek programmer for a safe, custom Vortech ECU calibration. It is designed for both manual and automatic transmissions and is 50-State emissions legal under CARB Executive Order D-213-35. At the core of this system is the gear-driven V-3 H67B centrifugal supercharger, specifically developed for the FA20 Boxer engine. Its internal oil reservoir eliminates the need for a connection to the oil pan, and a remote fluid drain hose facilitates easy fluid changes. The supercharger utilizes a high-efficiency, 5-axis machined billet impeller and a high-diffusion housing, tested in a compliant supercharger test cell. The kit also features an integrated air-to-air charge cooler with all-aluminum ducting and an oversized cooler core for maximum cooling efficiency with minimal pressure loss. Installation of this system is estimated to take between 4 to 6 hours. The kit includes all necessary belts, pulleys, a reusable high-flow air filter, and CNC-machined billet mounting bracketry with a black anodized finish for durability and aesthetics. Components like discharge duct connections use heat-resistant silicone sleeves and stainless steel clamps for secure and reliable connections. An optional Maxflow Race BOV Upgrade Assembly is available for a signature blow-off sound. This Vortech supercharger system is noted for its superior technology compared to roots-type blowers, offering greater efficiency and flow. The manufacturer highlights that Vortech systems provide significant horsepower gains for the cost and may even increase gas mileage when driven normally.
