Turboed mudder
Probably shouldnt be here, bet screw it. I've been toying with the idea of turboing a 4x4 truck, so I decided I'd turbo an engine on a run stand first, just to mess with it. Just started doing it, so I'll be updating it, but I figure how many people can say they have a beat up, cut up, loud *** turbo mudder? I know I'll be the first around here anyway.
We had a International 304 that came out of a dump truck, so we threw it on a bomb cart and built a run stand for it. For the exhaust, The pipes are realy long, but without access to a bender, and on a very very limited amount of capitol, we just made it work. I was origianlly going to go with a blow threw carb setup, but decided to make the carb on the intake side of the turbo instead. By doing it that way, Ill know how it will act because I would like to make my own intake with small straight runners for to keep up the low end torque, and for the cool factor. Heres what I have so far
I think it came off a old cummins, or so I was told but I dont have the numbers on hand to run them.

If you can get it to run and stay alive for a few minutes on the run stand, you'll have to find some way to load it to make it throw out some boost.....
I'm sure if the 304 is out of a dump truck the compression ratio will be in the neighborhood of 7.5:1 so you can throw some MAD BOOST at it.
Good luck with the "draw through" method.

Your mental dude. International's are low comppression, low-rpm, torque motors. My dad and I have a few scout 2's and I know about these motors. They don't need any power adders. I believe they get their max torque at 1200 rpm and horsepower maxes out at 3600 rpm. That motor can't handle a turbo. You'll blow it up. Good luck anyway dude. Hopefully you don't get hurt when it does explode.

Thats kind of one of the purposes of this engine, is to blow it up. Trust me we have thought of most if not all of the dangers, and can avoid them. The low c/r is why we picked this engine over some of the 305 and 350's we have laying in the shop. That way we dont have to worry as bad about melting a piston, and can focus more on spooling it up and tweaking it. Nothing "needs" a power adder, but why not? I can give you some reasons on why if you would like. And I'm not a "dude", look up the definition.

I've been thinking about slapping a turbo on my 351m, but lack the cash/skill to do it right now. This looks like a fun experiment if nothing else you'll learn a little about how to set up a turbo. keep us updated!

There's a kid around here that put a small turbo on an early Jeep Wrangler. He put a turbo on the factory four cylinder. It looks like business, lifted on 35's, but my brother knows the kid, and it NEVER sees dirt. He took it to a local jeep show and most responses were "gay", "retarded", "why", and "it's a four cylinder!". Don't think it went over real well, and he was standing there as these comments were made! Good luck blowing that thing up. Don't hurt yourself with flying debris when it lets loose!

We've got a oober thick plexiglass case that one of my freinds dad uses for when people watch him shoot his 50 cal. and crap like that, blowing stuff up pretty much. Its about 6 feet high, and 8 foot long wall with 2 hinges in it. That will protect from belts, fan, and piping. For the bottom end, there are removable plate 1 foot tall all the way around the oil pan and block.

started it up today. ran like a dream. I've got some exhaust leaks to fix, and some timing adjustments. Its got a holley 2 barrel on it, so I'm going to throw about a 20 or so heavier main jet in it, and see wat it does. I'm having some oil drainage issues on the turbo, but rotating it some should cure that I think. Anyone know what I should do to the timeing to get it to spool up some more? it just doesnt want to go any more than 4100, which I'm sure is pushing it but we want to get it to go up there.
I dont have any pics, but I got some crapppy phone videos. I'm using the digi cam tomorow, so Ill get some pics and videos 4 you guys.

What I was thinking to put load on it, was to unplug 2 opposing cylinders, so it will still be kind of balanced, but it will still be under more of a load to build the boost. Any thoughts on this?

Dude....
............I'd say your F'in Nutz......I like it......Can't wait to see more progress on this experiment....To draw a load is a good question. Not sure what to do there. I'm so drunk right now I can barely see.
peace out homey...
