I want to say hi to everyone first. I just joined to share my project with some fellow bronco owners. As the title says, I have installed a M90 supercharger off of a 3.8 supercoupe. I did some research and Eaton says it will work on motors ranging from 3.0L-5.7L. So it should work great on my 5.0L. I have purchased a 10% overdrive pulley to get some boost back from putting in on a larger motor. I'm also using the factory supercoupe intercooler to keep the heat down from spinning it faster. Here is a picture with the blower mounted and 6-rib drive hooked up.



I should have the intercooler and piping hooked up this weekend. By the way is sounds like a can of pissed off bee's!!

Lookin' good. There must have been some custom fab for the mounting of it. I have run a Powerdyne and Kenne Bell on a 302/349. I am currently swapping-in a 393 and will move the Kenne Bell and 347 to an 89 Stang I have.

Are you doing a Mass air Swap? Larger injectors? How are you going to tune it? Installing a boost guage?
The brackets to mount the blower are very easy to weld up. I have $30 in some steel to fab up the brackets. I will be doing a Mass-air swap from this place.

I already have 255lph fuel pump intank and have a FMU for the time being. I will be stepping up to 42lbs/hr injectors this winter. I will be installing a boost gauge and fuel pressure gauge to keep an eye on things.

:thumbupSounds as though you are on top of it! Cool project. Though you probably know there are better ways to tune than an FMU. I am going to add a wide band O2 sensor to tune with the TwEECer and to install an air to fuel ratio gauge to keep an eye on the mixture. The fuel pressure guage is good but the wide band O2 sensor, Tweecer, and guage will help me tune and keep an eye on things.

I over revved the 349 at 11lbs of boost, it went lean, knocked, and popped the ring land off of the number 5 piston.:doh0715: I should have been running less boost and have had the rev limiter adjusted.


How much boost do you expect? Is it a stock engine?

I have a buddy that owns a race shop with a dyno and he will tune it for me. The motor is stock right now but I will be doing a roller cam conversion, adding an edelbrock intake and headers. If I can make 7-8lbs of boost I would be more than happy with that. I just wanted to get some power back after the lift and tires. I put in some 4:10 gears but that didn't help that much.

I don't see how the tubing into and out of, but specifically out of the blower will work. Do you have drawings or any ideas?

Adam
The air inlet is on the back of the blower. The top of the blower is the pressure side. I have a custom "hat" that will sit on the top and direct the air flow out to the intercooler that sits beside the radiator (drivers side). I will have more pictures tonight for you guys.

Plan on using any boost retard devices?

Good luck holding the 5.0L together. :beer

The intercooler should keep me from having to use any retard devices. That and 92 octane.

Awsome! I would like a buddy with a dyno! Can he burn you a chip to retard timing, add fuel etc????

My 349 with the Powerdyne was very reliable once it was tuned. No intercooler and 9lbs of boost. I know the Kenne Bell would have been and will be with less boost and the rev limiter.


Damn! I didn't welcome you. So here is your unoffical welcome and salute:goodfinge:

He can tune anything. One of the best tuners in the state. Being intercooled will help me keep most of my timing. Supercharging is nothing new to me..........I used to work for Procharger. Now I work for Aeromotive, a fuel system company. www.aeromotiveinc.com

Here is a picture of the custom intercooler tube for the twin throttle body.

fawkin tits!

you shouldn't need 42 lb injectors though, 36's would be more than enough.


you have to love forced induction. Keep us posted, and welcome!

by the way, what size is the piping on the factory intercooler for the sc also what are the dimensions of the intercooler? I just wandered how much larger the sc is over the tc.
lastly were the sc intercoolers air to air or air to water?
The ID of the inlet/outlet are 2.375". These will be enlarged to almost 3" (got to love the dremel). The core measures 12x7.75x3. It is an air to air intercooler.

I can't take credit for the work on the throttle body piece. It's a pre made unit from a supercharger kit for a LT1 F-body.

looks like fun! where are you in kansas. im about 15 miles north of topeka
I'm in Overland Park

Just curious, what thought have you given to the rest of your drivetrain?

Big power and 35's might be a little harsh on that 8.8.
I just had the AOD rebuilt and beefed up. I'm not worried about the 8.8. I had a mustang that would pull 1.56 60' times on slicks with no problems. The mustang had 28 spline axles while the trucks have 31 spline. If I do break it, I will put a 9" in its place.

Can you get some better pics of the mounting brackets?

How did you setup the belt?
I will get some pictures of the brackets once I get all the tubing ran. I have to take if all off once I finish it to get it all powder coated. The brackets are so simple you will want to start your own M90 install!

The 8.8's can take 4-500hp. It is the side loads that kill them.
I think tires size plays a part in that with the extra leverage a larger tire can place on an axle, I think it would take less HP to break than in a mustang. Don't you agree?

Oh, for sure. The 8.8 is still a strong axle, and I doubt he'll be boosting when he's crawling on the rocks. Maybe in the mud, but he'll break junk regardless there. :toothless

Here is the intercooler with 3" inlet/outlets welded on. The ends have been bead rolled to keep things on under boost.
