Eaton Supercharger placement
Hi!
I am investigating the use of an Eaton MP90 supercharger for my 1980 Euro S. I would like to place the blower as far down in the V of the engine as possible and let it blow up through a watercooler(if hood clearance allows it) and into a plenum chamber almost like original.
I have seen at least two other projects on the list that has used Eatons, but both was placed on top of the intake. Is this because there is no room under the intake or is there other reasons?

Ian,
If you can find them take a look at the design schematics of the Ford F150 Ligntning, Mustang SVO, or GT 40. I was able to get a print-out of these (not GT40) from my Ford dealer. You may also look on e-bay for pictures. These systems have the SC on top blowing down through the cooler into a plenum which just has holes in it to the head's intake ports.
I seriously doubt that it is possible to put the blower down in the V. The coolant bridge gets in the way. I and others have looked closely at this.
There should be plenty of room down in the V for the charge cooler with the SC on top. I am considering re-doing my project to include a cooler down in the V but will probably finish it in the current design first.
I would seriously consider using the MP112 vs the MP90.
Hope that helps and keep us posted.

Ian,
I Have talked with the engineers at Eaton. The final word I received was that 'we' 928 community in the 32 valve engines should use the MP112.
If you intend to put the MP112 in the vee, You need to compensate for the blower driven pulley. You might get the hood to clear the blower when shut, but the pulley is a bit of work to do.
Plus the MP112 is the 4th generation. This has the internal blow off valve, and the actuator has multi mounting positions.
If you go to Eaton's homepage you can also download the dims for the SC.

OK, so there is a coolant bridge between the cylinder banks? I saw the '85 engine on Dozmans page had something there, are all blocks the same?
What is the reason 928's should use the MP112? Better flow?
It seems there also is a MP90 blower with internal blow off valve now by the way, or so I was told by the Norwegian importer.
It seems that putting the blower on top is the way to go with the Eaton. Am I better off with using a Vortech and regular intercooler? At least, this is proven technology on the 928. I desperatley need some more low-down torque though, I have the 3-speed auto box and my car is very lazy at low speeds.

It sounds as if there are some other things that need to be addressed before a supercharger is considered.
A swap to the four speed auto tranney comes to mind. I'm not an expert on autos as I am one of the chosen few with a 5 speed, but there are a bunch of guys on the list that can help you adjust your shift modulation, etc to get better performance.
I don't know anything about the 3 speed tranney, but I know everybody says that the 4 speed is quite a performer when set up properly.
you may want to add some info to your signature file like what model year car you have and any other options.
I would recommend making sure that your car is in tip-top shape before supercharging it. That not only means the engine, but also the tranny.

There are definite pro's and con's with each type of blower.
I am not sure how much research that you have done yet on superchargers and types, their characteristics, the pro's and con's of each type. But basically, the Eaton M90 may give you boost , but at at some point, the unit will not be efficient or provide enough boost for our engines. That is the basics. If your really interested we can chat offline, or feel free to talk to the engineers at Eaton. Please have specifications in front of you for the car, engine etc. It helps to tell them what your looking to do, and with what.

Dozman, I will be pleased if you would share some of your experiences offline! I will send you a mail.
DeltaP, as you say, I need to verify the state of my engine before attempting to increase performance. I have been looking for a 4-speed auto (my car does 110km/h in first gear!). I know someone on the list did this swap and I know it involves a little more than just swapping boxes, but if I find one, I would surely try.
I have made myself a signature now!

Hey Ian. I did the 4spd. auto swap on my 81.
In retrospect, it is pretty simple. I used an 84 transmission that did not need "body alterations" to fit as would an 87+ trans.
I found that I got a crossmember for no reason, as they looked the same, but they still might not me.
You need the newer TT. If you stick with 84, you don't need to change the half shafts. The wiring also matches up nicely. The shift cable needs some changing, and you need to buy a new DOWNSHIFT CABLE.
I am shouting about the DOWNSHIFT CABLE because it cost me a week. Nobody has one, new or used, and I had one made by my mechanic. The cable design is specific to the year of your trans.
This really woke up the car alot.
Now I want some boost, but shoudl really concentrate on my 89

Brendan, that is really good info on the 4spd. I hope a good 4spd with TT shows up near me. I guess the Toyota SC on Ebay is one of the smaller Eaton models, I would be surprised if it was the MP112 that is recommenden for 928ers.
By the way, I was quoted 2.585$(us) for a new MP90, anybody know if this is a fair price? Should I call Eaton and try to import myself?

Ian,
That is definately NOT a good price. You can buy the Eaton MP112 from the 2000 Ford Lightning from the Ford dealer for around $1200 new. You may need a longer nose drive but this can be had for $300 to $600 from Eaton. For about $2000 you can get the MP112, upper intake and intercooler. I was able to get them to quote me prices that were a bit lower by telling them that I may buy a few of them and giving them my business card.
