Eaton M90 supercharger 5.0 project

I am a industrial designer senior and not an enginer. I have designed and fabricated many parts for my 5.0 Mustang. I found a roots style blower from a 1994 Thunderbird SC, and whish to adapt it to my EEC-IV 5.0.
I am planning to fabricate a aluminum lower intake and top mounting the blower. This set up will be intercooled and uses the Eaton M90 supercharger. I was woundering if anyone had any suggestion, or ideas I should take into consideration in the design of this custom setup. Here are a few sight with some information about this supercharger.

To preface this post, I am not familiar with the Eaton outside it's use on the V-6. Having said that, I see no problems aside from the mechanical adaptation to manifold and drive system for your V-8. Drive ratio will probably need altering to achieve the proper boost curve for your application. As to the EEC-IV---I used it on my 83 Turbo-Coupe with good results. Just use a Bosche adjustable pressure regulator(J. Biddle American or,Steve Saleen, SanDiego) and altered timing to fool the unit. Not the best idea for performance, but cheap and it does work OK up to about 300 or so HP output. If you really want to do it right the first time use the Haltech ECU. It is a bit pricey, but works great.

If you are not 'locked in' to the Eaton, you might pull up the B&M site or the SVO site and have a 'look see'.

Thanks for the reply. My Mustang is not stock. I have a stage I super chip, BBK equal length headers, high flow cats, Warlock racing mufflers, custom built 75mm mass air flow meter. cold air intake, K&N conical filter, 24lbs injectors, Holley adjustable fuel regulator, Mallory ignition, Motorsport Coil, under drive pulleys, 1:6 roller rockers, Motorsport 10.5" clutch, and pro-5.0 shifter. given they are only bolt ON's. I chose the Eaton because of its price $300 bucks plus the cost of aluminum to build the manifold and I have access to a machine shop to fabricate parts. All you enginers out there how do you figure out the drive ratio of the pulleys. I can machine new ones if needed Thanks.....Drew

First, the Thunderbird SC blower is an M-62, not an M-90. For proper drive ratio, you can figure it out yourself if you know the airflow requirements of your engine. Go find the Eaton site, and they have output curves showing pressure vs airflow and temperature rise.

 

The latter intercooled Thunderbird SC were Eaton M90. The Buick and Pontiac used the Eaton M62. I have done my homework. The early super coups might of been Eaton M62 but I don't think so.

I pulled a blower from a 1990 SC in the fall, and the rotor measurements matched those given for the M-62 on the Eaton site.

 

This supercharger is off of a 1994 intercooled SC. Every super coup club I have found, says that it is a eaton M90. When it comes in the mail I will tear it down and measure it. You may be correct. I know the older super coups superchargers had a smaller inlet design and the 94-95 were considered a upgrade for the older super coups like the 1990 SC you pulled the blower from.

My main concern was that the M-62 wouldn't keep up with a 5.0 too well, but since it seems like it's an M-90, it should do fine.
