Supercharger System with Vortech V3 Si-Trim

The VF Engineering VFK21-01 is a comprehensive supercharger system meticulously designed to enhance the performance of the 1999-2003 BMW 7-Series 740, while preserving the vehicle's original quality, smoothness, and reliability. At the core of this system is the Vortech V3 Si-Trim supercharger, engineered to deliver a consistent 6 psi of boost. This setup boosts the stock 282 horsepower and 310 lb-ft of torque to an impressive 415 horsepower and 395 lb-ft of torque. VF Engineering's design philosophy emphasizes integrating robust Vortech supercharger technology with their own custom software expertise, refined over 15 years. All critical components are manufactured in California and undergo rigorous testing on both Mustang MD500AWD and in-house Dynojet 224XLC dynamometers. The system utilizes a CNC machined T3 anodized aluminum 6061-T6 bracket for secure mounting, a bolt-on crank pulley, and an active OEM tensioner with a dedicated serpentine belt to prevent slippage and ensure reliability. Custom-molded polypropylene air ducts maintain an OEM appearance and function, while an integrated Bosch bypass valve circuit ensures smooth off-throttle operation. Installation is designed to be non-intrusive and fully reversible, typically taking 7-9 hours. The system is turn-key ready, requiring no additional components or work. VF's Hex Flash ECU tuning programming cable and optional DIY programming cable offer convenient software installation, leveraging the latest BMW file versions. The supercharger system remains fully OBD2 compliant and is backed by a one-year unlimited mileage warranty. The linear power delivery is suitable for both automatic and manual transmissions, operating within conservative tolerances for an exceptional driving experience. A removable plastic air box with a K&N induction filter is included to accommodate varying climate conditions.
