M90 Supercharger

[Bad Attastude]

Well I don't want to turn this into a p$$$ing contest...

I've never seen one, heard discussion of them on the Thundebird Forum, (I have a 2002)or have read a road test or seen one on ebay.

I can't say you didn't yank a turbo off a V8 T Bird but i will leave it that Ford never produced that car for general consumption.

I'm willing to change my mind with a picture or a production count or a road test or even a parts listing from a site like advanced auto Parts or Rock Auto.

Not questioning your eyesite or your experience just the statement that Ford built them.

My apologies to the other posters I won't drag this out any longer. Maybe a post on the Stovehuggers for some other opinions.

The only turbocharged Ford V8 that I have ever heard of was a PowerStroke Diesel. The Turbo Birds were 2.4L (?) 4 cylinders and the Super Birds were 3.8L V6's. That doesn't mean you didn't happen across someones project V8 turbo Bird, but it wasn't factory.

We appreciate your sharing your turbo/EFI build and have enjoyed following your progress, and none of the following is anything but putting it in perspective. I bought this M90 seven years ago, long before you began your project. There have been twin turbo and EFI Studes running for close to twenty years now. Your project is a worthy endeavor, just understand it has been done several times before.

I appreciate that. I never say "I'm a first....." as far as doing projects or automobile history. For example, the turbocharger project, or the projects or history going back to the guys on the Yahoo chat, I never say that there's a first on anything when I conversed from the Yahoo chatroom or Studebaker forum. By stating an absolute fact, that would have gotten me called out to the carpet as far back as 2000 in the Yahoo chatroom. Anyway, about that M90 supercharger, I gotta see this thing....

You are invited to come over to my place in Joliet and read the Datson books.
I have all Stude versions.
I always enjoy your and you Dad's visits.
The old folks (I am 74) in the club may wonder "Who will take care of our beloved Studebakers after we croak?
Good to see you young guys love them also.

Here's the info on all the Eaton superchargers and specifically the M90. http://www.eaton.com/EatonCom/Produc.../M90/index.htm

It's weird - I've had my M90 on the shelf forever and as soon as I mentioned it, someone from this site tells a local street rod builder who is looking for one and he's over here with cash the next day. Now, I no longer have the M90.

I've still got a NOS M60, complete with throttle body, which I've had for even longer. GM used the M60 on millions of 3.8 V6s in the '90s. Eaton upgraded the design several times over the years. Someone in Detroit bought the surplus and sold the NOS units on eBay. I had planned to put this one on the 224" V8 in my '55 E12. Now, the E12 got the Packard V8, so maybe the M60 will go on a 259". It won't make huge racing boost on the larger engine, but would be a great street build.

has its outlet in the rear, I'll use a Y pipe to split the pressurized mix to each bank of intakes. As the inlet of the M90 is on top,

Wow, Sal, that's just the opposite of the one I had. Mine had the inlet at the rear and the outlet on top. Look at the photos from the Eaton website.

Thanks Bob, I'll have to remember to ask about those books next time we drop by. We love visiting the place as well, and we always have a great time too . You also know we have more than a couple in our own garage and around the homestead, but I will do my best to make sure I can get another 50 years out of them, even if a couple of them won't resemble what they resembled when they left the factory .

G'Day, First post on your forum has provided some interesting reading thus far, I see this is an old thread but I am in the process of putting an Eaton M90 onto my 61 Lark with a 259, I was wanting to know if anyone has actually done it, I have found a performance shop local in Australia that sells a bolt on adapter to take a Holley 4 barrel and will fabricate a new inlet manifold. Was interested to see how other may have set up a roots type on a Stude.

Just my opinion, but I would not try a turbo without fuel injection.

Back to Jack's dilema re: enrichment with the Chevy harness. There is an easy way to deal with that. Cartech sells an adjustable rising rate fuel pressure regulator (RRFPR) that is specifically made for a "non factory turbo" application.
Immediately upon building any boost, it will increase the fuel pressure to compensate for the lack of enrichment at the injectors. I have a factory turbo car with increased boost and use the Cartech "factory turbo" RRFPR (doesn't start to increase fuel pressure until my factory FPR is out of steam) and it works very well. Using a wide band O2 sensor, it doesn't take long to dial in.

Yes, I agree one would be better off with an ECU controlled enrichment, but we are talking budget here, right?

I saw this come up and was curious. But I sold off all my supercharger stuff when I moved. I had several of the M90s and an M112. Had a mock up ready as well, but the move was a bit traumatic. I had to sell off a bunch of stuff. It sucks to be in that position, but I've had a positive attitude all my life and it has turned out for the better. I still have my turbos which I like to use with carbs. I like the self-regulating nature of carbs. But as said above, check your plugs to make sure you never go too lean.

Wow! I just want pictures of when someone gets something running. Or it goes Hiroshima

[DEEPNHOCK]

Here's an old thread on another forum that has a guy doing an M90 with a Holley carb.
Don't know the results.

Along the lines that Lynn discussed, AEM makes an inexpensive A/F guage that will let you monitor and record how your engine is handling fuel. Just put one in my 74. Bob

The m 90 I have has the rear intake, dad was going to put it on his 61 but it got too hard and he has now gone to a more traditional VS57 blow through set up which I see some of you guys have done really well.
In my research the main items to tick off are having a boost referenced carb, and removing the coating on the rotors (on newer M90's) as the fuel fix softens and strips it over time and clogs things up, after talking with the guys from this performance shop http://www.aussiespeedshop.com who make some really cool kits for old straight six's etc it should all work really well. Worth a shot seeing as the supercharger is brand new and free. I just want to get the Lark on the road patina and all and have a bit of fun with a bit more poke.
