Eaton M90 Supercharger project M44

[FATHER]

You not need an intercooler if you have an eatonblwer like 362 or m90, why?!?!?! because you need the intercooler between the "blower and the engine, like turbos, so is imposible , if you put one intercooler in fron of bumber it not work.\

Today at work i think in put a blow off valve on my blower, is simple, y need to put a hole in the colector then i weld a 2" hose adapter, install the blow off on those adapter and eliminate the bypass valvel removing the vacumm hose, and thats is all, is easy, ut i need to stop the car for 4 days to remove the blower and all parts to weld the hose outlet, but i can do and i work on this soon

Very good idea father

I won't pretend to know a ton about forced induction...but what kind of tuning would need to be done to the DME to get this to work?

Really cool project you've got, Who. Keep us posted!!

FATHER, he was talking about REMOTE MOUNTING HIS S/C. It was just in general. The ford Eaton is mounted upside down, and does not bolt (mechanicly) to the engine. It DOES use an intercooler.

Just a bit of off topic/on topic talking.

FLINT, if I remember correctly, the M90 Ford S/C is mounted upside down, so the drive is on the wrong side for my S/C. I'm 99% positive it won't work.

[Flint01]

HAHA I forgot i posted that. yea theat what i was talking about but in the skeam of things it would not be a good idea.

I made it !! I have not found nearly enough info out there, so I'm doing it myself.

THEMIGHTYQUINN -- For now, I am going to run the stock program.... YEP !! I plan on running between 5 and 8 PSI at first. If I go with more boost, there will certainly be a tune, and larger injectors.

BLUEBIMMA -- You bet I will !!

FATHER -- You are going to eliminate your boost bypass ?? And run the BOV from where to where ? The reason I like the Eaton M90 so much is BECAUSE of the boost bypass. At idle you barely have any boost, then when you loose vacuum, you gain boost. I thought the BOV was used to vent boost after your throttle butterflies close, but this would mean having the S/C then TB.

[Flint01]

That right i forgot about that the m90 does have boost bypass, it would not good to have a Bov.

WhoNew: i not go to put the blow off for now, yust 3 minutes ago i order a smaller pulley from pulleyboys, i want to run 12 to 14psi, and reprograming the ECU with a good frien Neoh2ning, this guy have a Honda Acura aspirated with the 1.8engine, the time in the 1/4 is 11.3s with all parts on car, is the faster street honda in Puerto Rico, he said me that he want to gain like 50hp on my TI with the pulley and him laptop

Very nice. Let me know what else you add !!

I just got an e-mail back from ZZP. The fellow there said there is only 1 size for the snout on the GM Gen III M90. It's obviously the one I have, so I am going to try to figure out if I can machine the rear of the unit to fit a 90* elbow out the side. I'll post pictures tomorrow.

So todays activities, A little porting, not only to improve airflow, but also to reduce the heat created during operation.

Before

After


The bigger stuff was was done with a cutoff wheel. The fine detailing was done by hand with a small (12") rat tail file. The "humps" that were cut off were where the bolts go into the housing, the bolts will need to be shortened also, about 1/2" so they are flush with the housing.

Lookin good! Man I love this project and its not even mine! Ive been thinking about doing one of my own all week.

[WhoNew]

Honestly what is slowing me down the most, is the lack of machining tools. I need to get this manifold cut down, and fab the plate that will be welded right to it. I need to fab the top plate, that the supercharger will actually bolt to. I was thinking today, that I could weld in bolts from underneath, and have the manifold like a "studded" style.

any comments ?

A little background So i gave up on finding a short snout for my M90. I emailed ZZP (they specialize in the 3800 S/C) and the fellow there said there is only one snout that will fit, obviously the one I have. One idea was to cut the snout down (3"), and have the bearing race machined into the new shorter snout. this would also mean I would have to shorten the shaft, and have it machined also. This idea was abandoned due to strength concerns. So I had to come up with something....... now here is a disclaimer....... I am a proffesional, and I THINK I know what I am doing !!!! Now, if I had to do this all over again, I would NOT USE this style of Eaton. That being said, I don't discourage anyone from trying this out. A better choice would be the M62, or the m90 off of a ford supercoupe. I am using 2 1/2 " intake tubing, which measures 2 3/4" OD. Using a 2 3/4" hole saw, I made a cut on the SIDE of the housing Using the same hole saw, I cut only HALF of the intake tubing to match the intake hole in the housing. After using a few different tools to get the hole sorted out (smooth and ready for welding) Unfortunately, the hole saw wondered a bit, so some heavy grinding with my dremel, which is completely useless, to make the pipe fit properly.
