Hmmm. Looks like the competition is trying to keep up....

My father had to attend a Detroit Diesel school many years ago for his certification.

This was back in the two-stroke days and was telling on his return about the pair of 6-71 marine engines there on the floor that were rated for 400hp!

We found that tidbit of information fascinating as old he!! when it was all we could do to keep a 238hp version full of oil.....

Marine service also has the advantage of an infinite supply of cool water to keep lube oil, coolant and especially charge air temperatures lower even under high loads. With the heat rejection capability that marine engines have through their raw water heat exchangers, they can handle higher ratings than engines that are cooled by ambient air.

Guess you have not spent much time in a boat engine room. Unless fresh air is forced in temperature can get a bit toasty. The 4B250's melted down number 4 cylinder because the heat exchanger was under sized. I have thought about reversing the bilge blowers on my boat with 4B150's to force air in. Snoking

Actually, quite a bit. The vessels our engines power are more along the lines of the following:

When I refer to land-based engines that are "cooled by ambient air", I mean that the oil, coolant and charge air coolers are liquid-to-air or air-to-air respectively. Thus, their ultimate cooling capacities, regardless of size, are limited by the ambient air temperature whereas marine engines have, in effect, an infinite supply of raw water available to cool the heat exchangers. I'm not referring to the "ambient air" in the engine room of a vessel.

Wingate, what makes you think a programmer will be out for the little Cummins V-8, the EPA is after these guys big time!!!! The days of deletes and programmers are limited.

SNOKING

They will... there is too much of a market for diesel performance for the aftermarket not to get involved. There are already go-fast magic boxes out for my 14 model.
Deletes are something different, that was a blatant "in your face" to the EPA and those companies are now enjoying the wrath of the EPA. But, modules such as the Stryker Module are already available.
I think the little "light duty" cummins v8 will be a good engine, but it will show some of the same symptoms as a Ford or D-Max diesel when you start pushing it with aftermarket fueling.

 

[Wingate]

But there are a lot of 3208's V-8 CATs still running in boats!

SNOKING

Glad someone found a use for them! hahaha.. Although I "bleed yellow" I must say that I do not take responsibility of the 3200 series engine OR the 3100 A... hahaha

 

[TFucili]

I would also like to mention the dismal track record of even the Cummins brand of V-8 diesels, google up the V-903, VT-903 and lest we forget the "Triple Nickle" V-555.

They are still in service as mooring anchors for many a boat.........

Just sayin'...............

Very true. I grew up within about 30 miles of Mack headquarters/plants and their V-8 was also a flop. As for the two-cycle Detroit example, I just tell people those damn things were a freak of nature, and seemed to be happy screaming in any configuration and orientation. Definitely an exception.

 

[Wayne M.]

We just gave in the old GMC 6.5 rigs we had and got new F250 6.7's. I will hide behind the "everything is nice when new" thinking, but I couldn't own it. Guys are opening the hoods and pointing and gasping. I will admit that the seat is pretty awesome with nice side bolsters and it is fast.
At the end if the day I'm still happy with my 04.5.

We do have a couple 2011 6.7's in special app F550's. I saw one the other day and it was making a bad water pump bearing sound in the middle of the engine. Letting it develop.

Can you say " Silver 92" ?

 

[mwilson]

How about "Fuel Pincher" and "Fuel Squeezer"......I believe that both terms were used by Detroit Diesel in the 80's. I just can't remember which way it went, one term was used for the horrid 8.2L and the other for the 6V-92 / 8V92 truck engines.

Anyone else remember those with the picture of a fuel pump nozzle on the rocker cover breather? Showing my age here.

I can't believe I found the above....my talents have been wasted.......

"Where every down stroke can be a power stroke"......Furd musta' lifted the term from those guys......

 

[AH64ID]

pure genius

 

[SnoKing]

One of the design features of the inline engines was the blocks where the same on each end and can be swapped end for end to make a mirror image engine that rotates the over direction with a minimal different parts. Just about everything is reversable. Snoking

 

[Wayne M.]

Never knew of the fuel squeezer but the 8.2 pincher was another V8 flop. I remember the IH V8 that was in school buses. That was a mosquito killer!

 

[mwilson]

This is very close to what was on the breather...

 

[RVTRKN]

The TFL truck guys did a piece on the 2015 ford F-250. 860 trq, 440hp....

http://www.youtube.com/watch?v=wUrisZyhifk&list=TLMnJiMrCuhGweDIt7grLbSqRzGJq9npJ6


Ok Cummins, is it going to be 875 or 900 trq and 450 hp????

Back to the BS, Ford does this every time Cummins ups the HP/TQ numbers, the difference is the way they calculate the numbers, sort of like "Energy Efficiency Ratings". Some Engineer will calculate the "ifs" and "what about" if we change to a easier turning bearing, or a less restrictive gear set, but in reality it's HP increased, but is inflated. If you only drove Fords you would indeed think the HP increased, but if you compare the two brands, the Cummins will give real numbers, and you feel it, regardless of your loyalty.

I just spent 8,000 miles with a 2013 F350. It definitely has more horsepower. The problem is that it is top end. Unless you like flooring it all of the time it is wasted power. I'm back in a Cummins and I love driving my '13.

Never knew of the fuel squeezer but the 8.2 pincher was another V8 flop.

I loved the Detroit 8.2L V-8 Fuel Pincher. It put more money in my pocket replacing Ford and GM medium duty trucks with International trucks with DT466 engines than all the other V-8 diesel flops combined. I received verbal abuse and threats for International for refusing to sell 6.9L and 7.3L IDI diesel engines in medium duty trucks to my customers; however, I sold a few of International's 9.0L V-8 diesels (180 HP version) in very limited applications and those customers had very few problems with them

We ran vt903's in all of our 41' UTB's in the USCG and they were pretty good engines. Never really had any issues with them and usually put 3000 hours between overhauls. Were they bad in trucks or buses?

I even remember a Bertram that an old guy owned called the "Fuzzy Snapper" that had twin 555's and it seemed to run forever. No powerhouse but it ran good with zero issues.

It's the truck use that takes them out.

IH even tried the V-8 diesel thing with several proven large industrial and tractor engines, but when put in a truck were nothing but a repair disaster.
