Overview Technical Specs Fitment
The Magnuson MP45 is a hybrid/roots-style supercharger featuring an Eaton rotor assembly, which displaces 45 cubic inches per revolution.
Not only was the MP45 built to increase your engine's horsepower and torque, it was also designed to maintain your vehicle’s factory dependability, drivability, and fuel economy (under normal driving conditions). What’s more, “S Port” technology and an integral bypass are included in each 4th Generation Magna Charger for unparalleled performance. Adiabatic efficiency, delta temperature, and engine power requirements have all been improved, and the inlet and outlet track is now more than 90% volumetrically efficient, thanks to years of research.

The MP45 was engineered for small fuel injected engines, ranging in displacement from 1.0 to 2.4 liters. Although it may be tempting, to install the largest possible blower that will fit under your hood, Magnuson's engineers recommend selecting the smallest supercharger that will provide your desired boost level. Remember, proper supercharger sizing ensures that your car will achieve boost at the lowest possible RPM, thus maintaining the responsiveness and street-ability of your engine’s power band.

Eaton has produced original equipment versions of the MP45 for BMW, Mini, Mercedes (M 111 EVO and M271). The MP45 has also proven itself in a number of naturally aspirated to forced induction transformations, including the Mazda Miata NA and NB, Scion xB, and Pontiac Grand Am. As with Magnuson’s other bare superchargers the MP45 can be configured with a variety of options to meet your needs.

Generic head units have a 12 month/12,000 mile warranty against manufacturing defects. This only applies to the original head unit purchased from Magnuson.
