Okay, time for a build thread. Since I was fifteen I have wanted to do this project and finally I can start to finish it. I got the f350 frame shortened and the dana 60 coil conversion and all that stuff done two years ago and now it's time to get it completed. To start, I got my bronco out from the back of my house and parked it in the driveway.

I'm going to pull the fenders and front clip off and start on the engine, getting the 2300 TVS Magnacharger and UMP air intake in place and fabricate an intake manifold setup. Then I'll ship off the valve covers to be chromed and paint the engine black, cus' I like chrome on black. Matches my headers. I need to get out to the salvage yard and find a 7.3 with the serpentine belt system so I can transfer that over. When I get everything mocked up I'll start getting the rest of it done so that I can run some dyno tests. All opinions considered, there are going to be some questions answered by the time I'm done.

 

 

Since it doesn't look like you have a/c, I have to wonder why you want to convert to a serpentine setup? With the serpentine, your vaccum pump is moved to the top driver-side of the engine and would require a idler pulley for the a/c, no? The way your engine sits now make your top end look relatively open and well suited to mounting a supercharger. I would think your current setup lends itself nicely to what your planning on doing. I'd even guess you could run a hydroboost for the brakes and delete the vac pump altogether, although the pump on your setup now runs off of the alternator so it is pretty much out of the way to begin with.

 

serpentine is a lot cleaner, and lower profile.

 

I like the serpentine system mainly, but it will also depend on whether or not I run the supercharger directly off the crank. That's the plan but I'll have to get there and see what it looks like. I would like to keep it as close to the crank as possible but that limits me on what I can do. The idler won't get in the way whatever direction I decide to take, but I would like to have things as open as possible. I will most likely delete the vacuum pump, anything to clear things up.

 

That's why I like it. Just a better system. And congrats on you build, I'll try and beat you one of these days on the dyno numbers but you guys set the bar high.

 

Nice to see a build like this, its different, and Ill definately be following...

Dont bail on us...

 

There is actually a thread over over at OBN where a guy supercharged his Bronco with an Eaton M90. It ran pretty well for such a small supercharger and produced iirc 2psi at idle. For some reason, that I don't understand, he doesn't like the supercharger whine. Personally I love the sound. Anyway what is the size of that supercharger compared to an Eaton M112? I know it is a way more efficient blower for sure. I plan on supercharging my truck and pushing a turbo through it. I actually just made a long post about it over at TDS today. I'll have to copy and paste it here. It describes what I plan on doing pretty much every step of my build. I'll have to post some pics of my mount too when I get home.
How much boost total do you plan on running and what other plans do you have for your engine? Are you going to do a full engine build? With that setup or even a near stock engine, you could run quite a bit of fuel and boost but you could definitely push it harder with a full engine build with all the stuff done internally to make it last. Also do you plan on running a turbo with it or are you just gonna run it solo? I look forward to seeing you get it done! It should be an awesome project. Don't let anyone talk you out of it. Supercharging works on diesels too!! Sorry about all the questions builds like this just interest me cus they are similar to what I wanna do...

 

And there is the other top dog. I'm gonna getcha, don't you worry about that. I even have a few injector and intercooler tricks up my sleeve. So watch out boys!

 

Oh another thing I forgot, is that it might be hard to fit a bigger crank pulley. You might have to just have a smaller serpentine pulley made.

 

neat project! and as you know...take tons of pics!

 

Here is my plan:

My build will be a slow one over time. I will slowly upgrade the fuel system and other parts to see how well the stock engine rebuild lasts. If it fails, which I'm sure it will last longer than most think, I will do a full ***** to the wall build. It will hopefully be 400hp after all is said and done. As for boost on my engine, I have a stock turbo from a 93-93idit that I will compound into my Eaton M112 supercharger. My mount is already built but I am just doing a few things before I put it on. After I run that setup for a while and dyno it with a maxed out Moose Pump, I plan to swap the turbo out for either a Ford 6.0 Garrett vgt or a He351ve off a Cummins. At first I will blow the vgt into the supercharger like the other turbo and I will dyno it to see what it makes. I'm sure with a Vgt being a more efficient turbo over a 093 that I will make quite a bit more power in the same configuration. After I have tested that configuration, I will have my friend help me build a bypass system around the supercharger that when at a certain boost level, the sc will be bypassed and won't be producing any of the boost. With the turbo only producing boost on the top end, there will be more top end power due to the fact that the turbo is more efficient without the supercharger in front of it. But it will sacrifice a little mid-range power due to the fact that it will not be compounding after a certain boost. Plus I will gain a bit of power from the fact of not having the parasitic loss from the supercharger after it is bypassed. After all the testing, I will decide which setup I like the best and will run it that way. It should be a fun project over time. Another thing I forgot to is, I also plan to upgrade to a Db4 and also upgrade my cam too.

 

Thanks for the encouragement. I'm glad to see the interest. This is definitely going to get done. I'm not holding off school to go bass fishing... tempting... tempting... I rebuilt this engine when I was seventeen, not that long ago, and I regret not coating the pistons when I did it but I did get everything balanced. Other than that I'm happy with what I have. As far as lowering compression I wish I had but I'm not worried about it based on the amount of boost I will be running. I do have it studded so there's a plus. I want to keep this thing in it's efficiency range so I'm not going past 15psi @ 3300rpm. To much boost at idle is also not going to get me good gas MPG's around town and I want to keep things tight and efficient. No compound setup for me. Going strait supercharger. There are some questions that need answered and I've been wanting to do that for a while. I like that others are going for a supercharged system because I believe there are some common misconceptions concerning them and efficiency. I'd like to see your plans. I saw that m90 project and it was well intended, but in all honestly the m90 is just way to small. Even a whipple of similar cfm would be to small. And I think he knew that. As far as other mods, I have the headers on there already and when most other things are done I'll go get duel 3" exhaust done right. I have the TYPE4 cam ready to go in. I'm curious to see how that cam works with a supercharger. That's why I went with Russ's because I like that it has little more on the bottom end. As far as fuel goes I plan to do a test using stock BB's, stage 1"s and then moose misters and dyno testing them all. I want some real world comparisons on the same platform. While that is going on I will develop my injector system and see if it is feasible. If it is than I shouldn't need much more of a fuel delivery system than the rebuilt turbo pump I have sitting here but if not than I'm going to consider a pump upgrade. Quite a few options as far as fuel delivery goes, which I like. Can't forget the electric inline fuel pump conversion to go along with it. I'll have plenty of intake flow with that UMP with a real short distance to the supercharger inlet. I have an electric fan for a powerstroke that's coming, so goodby clutch fan!

 

Here are some pics of my SC and mount. The way I have it setup, is so that the turbo will blow into it and then it cal still go to the intercooler to cool the air down.

 

Had to step away for a while and didn't notice you posted. Sounds like you have it figured out. By running a turbo with it the m112 should provide plenty or air for sure. The Db4 would be good. That's where I'll go if my own system doesn't work out.
