The Magnuson 01-26-57-113-BL Magnum TVS2650 Supercharger System is a complete bolt-on forced-induction package for Toyota Tundra models equipped with the 3UR-FE 5.7L V8 Flex Fuel engine. Built around the Eaton TVS2650 high-helix rotor group, the system is engineered for high airflow, efficient charge-air cooling, and strong power delivery across the RPM range. Magnuson lists output at 560 horsepower and 563 lb-ft of torque at the crank, with stated gains of +143 hp and +128 lb-ft. The kit includes a handheld tuner, Flex Fuel calibration, intercooling hardware, and the components required for the specified installation.
Key Features & Specs:
Fitment:
The Magnum Performance Series is engineered around the Eaton TVS2650 rotor group, a high-flow supercharger platform designed to remain efficient across a broad operating range. Magnuson's housing uses optimized inlet porting and a large unrestricted discharge path to distribute compressed air across a large custom intercooler. Billet intercooler end caps and dual coolant inlet and outlet ports are designed to support high coolant flow and effective charge-air temperature control.
Magnuson's Dynamic Flow Technology focuses on reducing inlet restriction and improving airflow distribution through the supercharger housing. The system also uses CNC-machined ports to help distribute airflow efficiently into the engine cylinders. A cartridge-style billet front drive provides a bolt-on belt-drive arrangement and allows for future belt-line changes where applicable.
The vacuum bypass system is designed to unload the supercharger during idle and part-throttle operation, reducing unnecessary pumping load when boost is not required. When throttle demand increases, the system provides rapid boost response. Intercooled bypass air is recirculated through the supercharger to assist with cooldown between periods of higher-load operation.
This is designed as a complete supercharger package rather than a bare compressor assembly. The supplied handheld tuner and Flex Fuel calibration are included as part of the system, along with the supporting supercharger and cooling components required for the listed application.
Emissions & Warranty:
Magnuson lists this system as 50-state emissions legal under CARB Executive Order D-488-69. The supercharger system is backed by a 3-year / 36,000-mile limited warranty, subject to Magnuson's applicable warranty requirements and installation conditions.
