Powerful Technology:

Magna Charger’s new MP2300 HEMI supercharger is the same technology used in the new 638 horsepower, Corvette ZR1. Technically speaking, Magna Charger's new 6th generation hybrid-roots style supercharger design offers many performance benefits over other existing blower designs. It offers an advanced four-lobe, twin 160º high-helix design which produces cooler operating temperatures, increases air flow, has a wider operating range, higher pressure capability, and quieter operation.

With this technologically advanced system, your HEMI will achieve extreme power levels, while maintaining the street-ability of your ride. Magna Charger supercharger systems deliver power at the most frequently used areas of the torque curve, meaning that you will feel the power to the wheels on your daily driver as well as at the track. All of these benefits are achieved, while using less engine power by reducing parasitic engine drag during cruise situations. These cruising losses, common during normal driving, are further reduced by Magna Charger's unique integral bypass valve design.

The Complete Kit:

The package contains Magna Charger's all new patented cast aluminum high velocity intake manifold, MP2300 TVS supercharger, intercooler core, coolant circulation pump, and heat exchanger. Of course, all of the fittings, lines, belts, and hardware are included.

This kit comes with all the components needed for a neat and professional looking installation. Additionally, it is completely bolt-on. No welding, cutting, hood, or body modifications are required.

Quiet Operation:

Magnuson's ingenious integral bypass valve design is actuated by a vacuum canister near the throttle body; thereby preventing the supercharger from producing boost by re-circulating the induction air back to the supercharger inlet. Since your HEMI engine only sees boost a small amount of your total driving time, the bypass ensures you get better fuel economy and a quieter ride, while your engine is under vacuum. This is achieved without sacrificing any performance gains.

Specially designed inlet and outlet port geometry, in conjunction with the helix angled rotors, reduce pressure variations resulting in smoother discharge flow and a lower level of noise during operation. Furthermore, Magnuson's engineers have designed the ducting and mounting points with acoustics in mind. You'll hear the deep sound of your 392 HEMI engine without supercharger noise.

Fuel Economy:

A typical HEMI vehicle equipped with a Magnuson supercharger shows no fuel economy penalty for highway driving and only a one mile per gallon decrease for city driving. The problem is, most owners cannot resist the fun of experiencing the power of their newly supercharged HEMI engines.

Quality and Reliability:

Magna Charger has been manufacturing top quality superchargers for over 40 years. Numerous 500 hour durability tests established have been conducted on Magnuson superchargers, proving their products have industry leading durability and quality. Additionally, numerous vehicles have successfully completed 100,000 mile vehicle durability tests.

Magnuson Supercharger vs. a Turbocharger:

The low RPM power that a supercharger yields is more useful the than high end power that a turbo provides, especially for large displacement HEMI engines. At lower engine RPMs a Magnuson Supercharger will provide a much greater average in under the curve horsepower and torque over a turbocharged system.

This is largely because a supercharger is connected by an engine belt, instead of driven by exhaust gases like a turbo. Superchargers pump extra air into the engine in direct relationship to crankshaft speed. Power is delivered instantly and, unlike a turbo no lag occurs, boost is instantaneous.

In addition to having the advantage of no turbo lag, each Magnuson supercharger also features a self-contained lubrication system. This simplifies the installation and does not add excess heat to the engine oil or require any additional maintenance. No oil to change. No dip sticks to check.


The Magnuson Moss Warranty Act (US Code-Title 15, Chapter 50, Sections 2301-2312) states that the manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to failure in the vehicle. We recommend working with performance oriented dealerships and shops, such as Arrington Engines. For additional peace of mind, Magnuson Products offers a limited extended 3-year/ 36,000-mile warranty for $200 that helps with potential problems with the dealership.
