5.0 with an Eaton M90?

Reply #30
I think it would be cooler then shiznit to do the same thing with two m62's, as there eaisier to find and two would probably be a better setup for a 302 then a single m90.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Excellent write up - just need to correct the above as the Eaton is not a screw type.


I agree, excellent write up, just needs some pics to help explain it in detail even further....

and yeah, the Eaton is a roots style, not twin screw.

if u are going to do it ,at least get a 94-95 s-model blower
the 89-93 model WILL grenade and tear up everything includeing the engine
mike

No.  The early models do not have Teflon coated rotors which means a greater rotor separation.  They will not grenade.  They just take more turning to generate more boost and therefore create more heat.

The S model has a revised outlet that flows more air than the early models.  Both work fine.  Both are easy to overhaul.  You can even swap coated rotors into your early model housing.

The 1994-95 models have a revised inlet as well. They will produce more boost at a lower RPM, but it is noting to sweat as stated.

There are a few things I wanted to elaborate on since there have been a few questions. What I posted last night was just from memory and I was not looking at anything...all of my stuff is at home in Illinois and I am stationed in Australia....so I will try to work with what I have......I tried to make last nights post condensed so that I was not boring to anyone and sounded like I was just running on.

First off, before adding anything or taking stuff apart, position the blower assembly with the inlet and Throttle Body where you want it to sit in the engine bay. Leave room near the shock tower as the motor will need the room to rotate that direction under load. Also your car will need maintenance so keep in mind the plugs will need to be changed.

Pictures.....OK...here is our subject. An Explorer intaked 5.0 with A/C delete.



First thing I forget to mention.....I do not have photo shop or paint, as I took them off my computer when fixing a windows issue. You will have to use your imagination...Sorry.....Your blower bracket will have to fit behind the alternator, on top of the fuel rails and  the pulley will have to reside over the top of the tensioner attachment point, lined up with the crank.

Next, In this picture the factory lift point will have to be modified (cut off the top) and a steel bracket welded to it to support the blower base bracket from the front pass side.



In this next picture (this is the drivers side but applies to the pass side as well), The stud (barely visible behind the plug wire) used to bolt down the intake is used on the passenger side to hold the alternator steel bracket. This stud will have to be lengthened (longer studs can be purchased at a parts store) and a steel sleeve will be sandwiched between the alternator bracket with a nut on top. This steel sleeve will be used as a bracket attachment point and will be welded to a piece of steel that supports the blower bracket base on the front drivers side.



Next, another bracket attachment point will be made about 3 or 4 bolts back from the first on the passengers side of the intake. It should be about 2-3" tall and 6-8 inches back from the first attachment point. There is already a stud there as it is used to hold the brass heater hoses to the intake. A modified steel alternator support bracket works great and can utilize this same stud if you are creative. That should hold the passengers side back of your blower base bracket and another support, similar to the first two you made, coming from the Holley carb base where the elbow bolts to the intake to hold the drivers side in the rear of the blower base bracket. 

Your intake elbow will be pointing to the other side of the motor, so it will not be effecting you.

One of the points I forgot to add will be the lack of hood clearance, so you will have to get a little creative. Another thing is the SC TPS will have to be modified to fit the Fox 5.0 harness. The wires are the same color so it is fairly straight forward, but it will be a hybrid TPS of the Fox 5.0 plug and the MN-12 SC TPS to utilize the SC throttle body.

The discharge outlet is ball and socket flanging....cool cause it does not leak alot plus exhaust uses the same thing!!! Cut the corresponding factory discharge tube( that leads to the intercooler) in half to remove the correct threaded piece that holds it to the discharge housing (save it for later). Have a large 2 1/2" to 3" pipe bent at an exhaust shop to get the intake to match up to the blower discharge and the engine intake . Flare the ball and socket end to match the discharge outlet. Place the threaded ball and socket "goofy" piece from the original discharge tube onto the piece of exhaust tubing and weld a  onto the other end that mates to a Ford 5.0 throttle body. Screw them together.


Lastly, I remembered this morning this will not work as the original discharge tube is threaded and the blower end is not. I ended up just cutting the "nut" off of the discharge tube and using a piece of silicone hose and clamps, like the  at the parts store for the import guys. 

I hope this helps!!! If you have anymore questions please ask.

what about if you moved the alt. down lower as in where it would be if you had a Vortech...  that would free up some more space.....  and tidy it up a bit too....  or maybe even move it over to where the AC was.....

I have a spare Eaton laying around and I think I am seriously going to try this out this spring, as the Cougar is soon to come off the road (at least from DD status).

Here's a picture of the custom job some guy named "Alex" did on a Fox car (LTD or something like that). He ran 11 psi and was running in the mid 11's IIRC.

I've made up my mind we are for sure doing this. I think this is the cheapest way to make extra horsepower. I mean honestly why not do this? I don't understand why more people don't do this.

Then why do so many people have these on their cars and benefit from them?

Yes, it does have enough to feed a 302 into the 11's. Go search for AlexLTDLX on the Corral - he went 11.43 @ 119 MPH using the M90 in the picture above. Granted that's about it's limit, but not everybody is looking to make a career out of drag racing.

the fab work involved to make it work. had one guy on here try to supercharge a factory turbo coupe(while keeping the turbo), and it didnt last long at all. id say within a week of getting it running. havent seen him post since.

Thus the term "intercooler" for an aircharge cooler that goes in between two different boost stages. That person's project was doomed from the git-go - probably melted the pistons.

Well bad news I took the car out last night and it was running better than ever at 25psi if felt FAST. Today I was taking it out and saw smoke and smelled like antifreeze i checked where it was coming from and it was between my header and turbo. I picked my dipstick out while the engine running and oil started gushing out so im positive I blew a hg. I think im gonna might as well swap the engine now to the other one i have that looks to have a recent rebuild and give this old junkyard dog a rest and port my N/A head Im currently running. Also has anyone here tried the slider tc cam with ranger roller followers did you notice a improvement ant bad outcomes? Well will keep you posted.


It didn't really fit under the hood too well...A huge cowl at that.






I still give him credit for trying.
