"Turning up" a 3020?

[RickB]

You would have a hard time finding one around here that didn't have some fuel shoot to it. I could mention dozens of examples, but far the best is an old local farmer who has 3 4430's that were turned up shortly after he bought them new. I bet they must have 20k hours on them and still running today. No pyrometers and I guarantee you he has never cut them any slack.

I have ever seen any issues with bumping them by 25 to 30 HP.

That's a tractor with a factory turbo. Overfueling a NA engine leads to a little bit of power and a lot of smoke. I plowed thousands of acres with a bone stock 3020 and IH 720 4-18" plow; most of it in 4th gear.

Seems a conservatively designed engine should be able to be "turned up" as that allows a wide range of
applications, i.e. continuous duty in a mine or ship. Look at what Cat did to the 3208, more than doubled the hp from 210 to
450 in marine applications. My understanding is that just pushing more fuel or just pushing more air doesn't get you very far, other than smoke,
vs. feeding the engine an ideal balance for its load and rpm. Which since I'm not a decent mechanic is all a bit of voodoo and witchcraft to me.
But I do know that if I ever get a miniature diesel engine to run my pencil sharpener, it will need to be common rail...and run on vegetable oil so it smells like
popcorn. Wouldn't that be a hoot to have on your desk.

I think turbocharging diesels is a natural, no pun intended, almost all of them are heavy duty enough to withstand some more stress/pressure. And from what I have read, they actually
get more fuel efficient when more air is added, I suppose to a point. As others have said, it's all about preventing them from
overheating. Change the oil and keep them typically under 200 degrees and most of our diesels will outlast us, the owners. Which is the way it should be.
And feed them clean fuel, which is always a challenge.

Those New Gen JD's were tough tractors, you look at one and just know it was built to be handed down from father to son.

Before we started any work, I put it on the dyno to check power. It was only producing 38 hp. Spec was 59 I believe. I replaced fuel and air filters and gained 10 hp.

You must have given the owner of the 3010 a "good lecture on the necessity of changing filters in a timely manner" if he ran the turboed 3010 20 more years with no problems.
