Magnuson Supercharger System | 2005-2015 Tacoma

Magnuson 4.0L Supercharger System

Unleash the full potential of your second-generation Tacoma with the Magnuson MP90 Supercharger System. Engineered specifically for the 4.0L 1GR-FE V6 engine, this premium, fully integrated system delivers serious, predictable truck power without sacrificing daily drivability.

Running at approximately 6 psi of boost, this system transforms your truck's performance by pumping out an impressive 305 horsepower and 335 lb-ft of torque at the crank on an otherwise unmodified vehicle. Whether you are towing a trailer up a steep mountain pass, navigating technical off-road trails, or merging onto the highway, this kit provides the robust low-end torque and power your Tacoma needs.

Instant Response & High-Efficiency Roots Technology

• At the core of this system is Eaton's proven fifth-generation MP90 supercharger unit. Featuring a positive-displacement, Roots-style design with lightweight, three-lobe, 60-degree twisted rotors, this system delivers instantaneous power the moment you press the throttle. Unlike turbochargers or centrifugal systems, there is zero perceived lag-just a massive, linear increase in torque across the entire RPM powerband.
• Because a Roots-style supercharger does not compress air internally between the rotors, it operates with incredible efficiency during light-throttle and highway cruising. An internal bypass valve allows unwanted air to circulate freely when power isn't needed, resulting in negligible parasitic drag and maximizing your fuel economy on long road trips.

Advanced Single-Cast Design & Intercooler Integration

• The supercharger housing and intake manifold are cast and assembled as a single, compact unit. This seamless engineering minimizes overall height for perfect under-hood packaging while completely eliminating external gasket lines and potential boost leak points.
• Air enters through a high-velocity flow path and feeds evenly into an unrestricted plenum. From there the air charge passes through dual, internal liquid-to-air charge coolers. Featuring advanced louvered-fin designs and extruded multi-rib tubing, these intercoolers maximize heat extraction with minimal pressure drop. The cooled air is then delivered to the cylinders via precision-tapered individual runners to optimize airflow and eliminate port cross-fire, ensuring consistent, heat-resistant power from startup to shutdown.
