Magnum Powers Introduces the "MP Extreme" (MPx) an All New Supercharger Case for the T-Bird-SC!

The MPx Supercharger Case with a matching Intake Plenum is being offered at the unbelievably low Introduction price of Only $1125!


The MPx 90 cubic inch Supercharger case pictured is cast from 356-T6 aluminum that is stronger then the factory Eaton material. It has longer intake and exit port duration then the Eaton M90 allowing the supercharger to be spun much faster without loosing volumetric efficiency, which results in the generation of excessive heat.

In addition to the stronger 356-T6 material the MPx case has thicker wall thicknesses and a stiffening boss running the full length creating a very stiff case that will not flex while under load.

Since the case is a new casting there is no reason to send your M90 to Magnum Powers to have it ported. Simply order the case, which comes with a MP Intake Plenum, install your rotors, fill it with supercharger fluid and have fun.

The independent test results below were conducted by David Dalke of Supercoupes Unlimited.

Magnum Powers High Performance Inlet Plenum

The MP Inlet Plenum now comes in a Polished Aluminum Version for only $50 more.


Polished Plenum shown

Designed for the 1989 to 1995 Thunderbird Super Coupe and Cougar XR7, this Supercharger Inlet Plenum adds power throughout the RPM range and can also be used on Ford V6 Mustang that have benn upgraded with a Eaton Supercharger. Hundreds of hours were required to develop and test this plenum resulting in significant power gains from 3000 RPM to 5600 RPM where an additional 40 horsepower is gained over a ported stock plenum coupled to a larger then stock 70 mm throttle body.

Even higher horsepower gains could be claimed if the Magnum Powers Plenum was compared to a stock plenum and throttle body.

Many hours were required on the flow bench and "Blower Dyno" to develop its shape for maximum performance. During development it was discovered the Eaton supercharger likes a very large intake cross section, which is why this 85mm plenum was developed. There is no way to port a stock plenum to flow as much air as the Magnum Powers Plenum. Magnum Powers plenum and throttle body are used on Kevin Leitum's record setting SC.

The 85mm inlet can accept any throttle body from stock up to the Magnum Powers 85MM Throttle Body, the largest available anywhere.

Roots type superchargers require low inlet restriction which is why this plenum has such a large cross-sectional area throughout its entire length not just at the ends. Hundreds of hours were spent on the flow bench and "Blower Dyno" to ensure every turn was just right for maximum air flow. That Eaton Blower can get every cubic inch it can take when fed by Magnum Powers Intake Components. During development, a lot of things were tried, everything from cutting, welding, and grinding on a stock plenum to the construction and test of a 90mm prototype. Finally this 85mm design was selected as the best compromise, so you can see this shape did not come about by accident or science-fiction, it is the result of real science and a lot of hard work.

As you can see the appearance is great, the lines are clean and it looks good in that engine compartment. All connections to the various vacuum hoses are provided for with brass fittings included in the price. An EGR adaptor is available for SC's requiring it, be sure to ask for that option if your car has one when ordering.

Here is seen the plenum's back side where provisions for vacuum hose connections are made so the front is clean and free of hoses. All mounting holes are in the factory positions so this plenum is a bolt on.

 

Manufactured from only top quality materials this plenum is cast from 356-T6 aluminum and uses stainless steel for the bypass valve components and is sold complete requiring nothing from your old plenum.

Don't settle for anything less then the best in performance and quality!

Remember, the Inlet Plenum is now available Polished for only $50.00 more then the Powder Coated version.

For use with late model Eaton blowers with the rectangular port only.
