Silly me, thinking that letting an engine turn and be happy versus dragging it's ass off all day might actually net better economy?

I think the problem with the V8 engines were people wanting to run them against the limiter, back them down a couple tenths and they will run a long time.

Unless it's a 3208...

Turbocharged engines are most efficient under boost, lower rpm = higher torque = higher boost. If engines cant take it they are just crap.

[regcanfan]

I've never seen a math equation with 3 = signs.

Doesn't fuel factor in when creating boost. Kind of thought low rpm high boost, takes fuel to make boost.

Only engines that were designed to be run at lower RPM there genius.

We have farm tractors here that run great at 2200RPM and get good economy, but run them at 1800RPM and they drink fuel and have now power.


Why I responded to you, I don't know...you won't understand my post and tell me how wrong I am and I must be doing it wrong. Oh well.

And in a pulling tractor! The 3208, DT466 and V903 are great examples of engines that will make thousands of HP if you replace ALL the OEM parts including the block.

Just had a D12 in here that is a turd at low RPM, is that because of the European tuning?

No. Thats a US volvo. Poor US tuning. If it was a euro spec youd turn that little c18 in after drivin it...

I’ve heard those euro motors will run daylight to dark in 4hrs. Too bad this one goes through belt tensioners every 50k miles. And of course it’s a Volvo branded pos that’s almost $400 where those “expensive” Dayco ones for a Cat are less than $100

903s are stock block, they just put sleeves in them so thick there is no chance of ever hurting the cylinder walls, just the bottom end.

I had at least 4 cranks for them and there was zero market for them.

I’m sure they are billet cranks so likely not a lot of use.

Do any of you guys have an n14 ecm fixing place you'd recommend? Midwest ecm repair pops up a lot and they seem reasonable. Friend of mine has one dying, still runs, just badly.

We just core them with Weller. Don’t get one from Cummins.

I didn't think about them, we have a local place that deals with Weller, I'll have him call them too.

Tractor left last fall, so my brother decided he wants to get more serious pulling a semi. It is a little long but speced right.

What other details? Motor?

What’s the wheel base? Looks like it may be close to my FLC, which is 221”. Honestly I don’t know if shorter is necessarily better. My dad shortened his frame 2’ years ago. He keeps talking about going back. Couple other guys bought hot rods and lengthened the frame from where the previous owner had them at.

Ddec 3 Detroit. Wheel base is 270 everything we have played with that 200 to 230 range seems to be pretty good.

It's a D12. It's NOT a turd on the low end. It's a turd everywhere. Why do you think they last so long?

Well I’m not going to argue with that.
