Your towing rigs and trailers

Small displacement engines usually live short lives once the man sized loads get hooked to em
Usually is correct. If it's built to handle the load (which both the 2.7L and 3.5L engines are reported to be), it will be fine.

So the question for some is; do I really want to bounce around in that rattly diesel pickup every day,,when a lighter, less expensive truck will pull my tractor for the few times that I need to every year?

The underlying theory comes down to duty cycles. Can these small engines making big power have the duty cycle of a light duty truck or a big rig. This is where the surface area of the crank bearings come into play. The ecoboost have giant crank bearings, even bigger than a 6.7 cummins. Like I said, they are purpose built to handle boost and torque. They are also made out of compacted graphite iron blocks, which are a lot stronger than the old cast iron blocks.

I know that a 6.7 powerstroke makes big power, but they can't make that power for long. They run out of cooling capacity even with the two radiators.

Big rigs have such big blocks and big radiators they can make high power for a lot longer than smaller trucks, even though the HP/ftlbs are getting a lot closer. The block is an actual heat sink on those things.

Years ago when we first started our business I had an older Ford 7.3idi with a Banks Turbo. I turned up the pump and greatly increased the HP, but was never able to really use that extra power due to engine overheating, and I toasted the automatic trans a couple of times. You need the entire system to work together.

I've always wondered that. Light trucks are fine for occasional use, but if you are going to be working it hard all of the time it's best to spend the money and get the proper tool for the job the first time.

Big engine working easy lasts longer than little engine working hard.

Lets not get too crazy....:laughing:
If you are suggesting an 2-3 liter eco boost gas engine is in the same league as a 6.7L Cummins, I got some prime swampland in Arkansas I can sell you for 100k/acre :rolleyes:
Do you really think this 6.7L Cummins powered Freighliner 6x6 with a water tank could be powered by a Ford eco boost gas engine and last more that a few hundred miles?

I just laugh at these kids with their new trucks with “ 400 horsepower “ thinking theyre even in the same league as a true medium or heavy duty truck engine...:confused2:
Heck I bet a little DT360 or DT466 would outlast an eco boost engine by 3X in anything much above a 15,000GVWR truck.

If you needed to pull 15,000lbs or more up mountains, what would you rather have a 6.7 powerstoke or a 3.5L ecoboost? :confused:
BTW many of the diesels have had CGI blocks for 10+ years.

The internal bearing size is actually bigger than a 6.7 cummins. Add in the forged internals and piston coolers...

When you have to use extremes for an example, I will too...besides, 15k is far outside the ecoboost rating.

Why not use a DD15?

That's the thing with extremes...we can one up each other all day.

Your right, the CGI came out in 2011 with the 6.7 powerstroke. A lot of tech from that motor flowed over to the 3.5 ecoboost. But the purpose of the 3.5 and 6.7 are different, agree?
