I just ordered an Eaton M112 Roots blower that I am going to attempt to fabricate onto my 91 383 TPI. This was a brand new factory replacment blower for the 01 Lightnings. I haven't measured it yet, but it seems like the fuel rail may be a little bit narrow to fit the supercarger between it. I will delete the runners, weld an air/water intercooler above the lower intake, and keep the plenum mounted above the supercharger. It may almost be hidden

I am also looking for a lower TPI intake to do some welding on. Anyone have one for sale cheap or know where I can locate one? I may need two so I can cut one apart and find all the passages.

Lastly, I have a local custom supercharger shop that is going to help me with the fabrication. Is there any intrest from people here to buy a complete air-water intercooled Eaton M112 TPI setup for just at or slightly under $3K.


Thanks for the input!

I would have went with a ProCharger D-1 with 3-row intercooler. The oiling is self contained and it would be a much easier install, especially if you ever have to take it off, the car would still be drivable due to still having the whole intake in tact.

 

I am not big on centrifugal superchargers, so I skipped over that. They may be great for track applications, but overall I prefer the roots or twin screw style ones. I was going to go with a whipple charger or lysholm screw (most efficient stuff out there) but since I got a deal on the eaton M112 it was the winner.

The other reason I wanted to go this route (vs centrifugal) is this way I can completley eliminate the crappy restrictive runners. I know there are aftermarket pieces available (I'll have a set for sale soon) but IMO it would be easier to just eliminate all that.

On a side note, does anyone have autocad drawings to scale of the TPI units?

 

make sure you post pics of the build up, sounds pretty interesting!

 

I am in the proccess of doing almost the same thing and have been trying to figure it out my self. 87z28 body 383tpi 5spd. I found a new old stock bohnalite 6-71 real cheap! and i talked to a fab-shop welder today about cutting the runners and making a custom intake that would work. but i like your idea better. Any ideas for fuel rails and injectors? I would love to see some picks on what you come up with. I am having a ?upper-intake? that is going to hold the throttle body made for now. can wait to see what shows up here for advice keep me posted. Also I have been thinking about the best way to add nos to this type of set-up nothing big just a 100hp shot or so. thanks

 

wow that's something i've never heard of i would just slap a centrifugal sc on there and be done with it, but a roots style blower on a tpi car sounds pretty cool, i could see having it done on a carb engine real easily but not tpi. i think if you could somehow take the fuel injection system off of the ford and then combine the lower half of the lower intake for the tpi with the upper half of the ford intake so it would all match up correctly, but then you will probably run into problems with sensors.
i don't know exactly, but definitely keep us posted on progress and pics too!

 

I have a spare tpi intake we can PM on it but, I was thinking of this several years ago and thought that a vortec truck intake would be better since you could for one run the better vortec heads and second the whole bottom intake is already open. you would still have alot of cutting and welding to do and would need to add injector bungs where you want them.

 

The mp112 is a nice unit but it will barely fill the needs of a 350....yet a 383. If you get this working, I would seriously consider a upgrade to the 122H or the new Eaton 2.3L blower.
