I need the dimensions for the third gen M90.
Talking about this one:

The only "blueprint" i can seem to find is this one, and it seems to have a shorter snout and no air bypass valve.

So if someone have some blueprints of the right one, or would be willing to take some measurements that would be great.

Planning on supercharging my 86 Mazda Rx7, and the Eaton M90 seems like a realy good unit.

Also if someone know about affordable solutions to shortening the snout that would be good.

First off i highly doubt you can shorten the snout. Second i don't think anyone here has a blueprint of the M90. Third the M62 has a shorter snout and would work fine for the displacement of your RX7 if it's the stock engine.

Someone might have a CAD drawing of it but i have never seen anything.

Here is a bit more on the eaton SC. http://www.3800supercharger.net/

No blueprints though, although google images shows promise... https://www.google.com/search?q=eaton+m90+drawing&espv=210&es_sm=93&tbm=isch&tbo=u&source=univ&sa=X&ei=nhZDU6WrBYrC2wWSioHQDw&ved=0CCcQsAQ&biw=1157&bih=733

I know the eaton blowers were used on other cars with various snout lengths. I bet you could find a good used snout made for a ford or other model that can bolt right on. Maybe contact http://www.magnacharger.com/ They are the sales distributor for eaton SC's and used to have a ton of info on their site about the M90.

Thanks for the answers.

The problem with the google images is that none of them had the longer casing with internal air bypass valve, and the snout looks shorter than the 3800 m90's. And when i said blueprint it might have been to optimistic, first of i'm looking for the basic dimensions to make shure i can get it to work, or if i need to get one designed for an external air bypass valve.

I'm going to look into the cfm numbers for my engine, to see if it would be ok to run a m62. But i would also need the basic dimensions of one.

CFM of the M90 and M62 for the 3800 at least is the same/very close the M62 uses a much smaller pulley stock. And don't hold me to this but i believe at one time one of the members had a CAD drawing of a gen 3 M62 for the bonneville.
