Have ever driven or towed with a dodge cummins?? The guy i use to work for had a 96 and an 08. I much prefer my 02 Ford. Cummins has power, but it seems like it is in a short range. Maybe if you could put a ten speed behind it I would like it better. His 08 would out run my 02, buy drove like crap.

 

You should go ahead and ban me. I have a history of getting banned from IB owned sites so it is really just a matter of time.

Also, if he is demonstrably acting like a troll , how is it an insult? He makes inane claims that are patently false and will not answer logical, thought out questions. For example, here is the fourth time I have asked this question in this thread with no answer from the "my gasser will out pull your POS diesel" crowd.

""You probably know more about these motors than I do seeing I just have owned and used both over a 3 yr period, each. But, if gas is so great at pulling and long term use, why is nearly every heavy duty commercial application diesel: Semis, Work Boats, Cargo Ships, etc. I really don't know the answer and would like your thoughts on this."

I'll try. It's just my opinion so don't shoot me. I had a 3208 Cat turbo in my gillnetter. It put out about 310 horses. It's a big heavy motor but was well suited to the task at hand. While my V10 puts out substantially more horsepower I would not consider it an ideal application for this commercial fishing boat. There are, however, guys that do run gas engines. But the big commercial diesels are better suited in my humble opinion. Again, debatable. The difference between the commercial diesels and automotive/light truck applications is size. The bigger, the better. Size helps dissipate heat and is stronger. So, to answer your question: Why is nearly every heavy duty commercial application diesel?, I point you to two excellent articles - gas vs. diesel in marine applications. It makes many good points. Happy reading!

While I'm at I'll put in my two cents for this thread.

I bought a gas engine 'cause I expect to put on under 5,000 mile a year. And towing heavy loads will only be occasional.

I would've bought a diesel if I was going to put on some serious mileage and/or do some serious towing.

David Pascoe is a genius. I pored over this site before my last boat purchase seveal years ago. His articles that you list are very informative. Thanks.

 

He may know something about boats, but I think he needs to brush up on his physics:

"Diesel becomes the better choice in direct proportion to the amount of weight being propelled. In a word, the reason is "torque." Horse power and torque are two different measures of power. Torque is a measure of the kinetic energy that builds up in a rotating engine. The higher the torque, the more power it takes to slow the engine down or, in other words, it takes more power to make it work harder or, the engine will carry a heavier load with less strain. Diesel engines develop more torque for several reasons. One is because of their greater mass: heavier parts develop more kinetic energy. But they also have compression ratios three times that of a gas engine, which also develops more torque. Gas engines develop most of their horse power at the top end of their RPM curve; diesels develop more power lower on the speed curve because of their greater torque, which can be thought of as the reserve power behind the rotating shaft. "

 

Kel; Torque is not someting that builds up. Torque has nothing to do with slowing the engine down and strain is not part of the equation. The diesels' mass has nothing to do with thier ability to produce power. Heavier parts have nothing to do with making power and developing kenetic energy. Compression ratio in itself is not a measure of making power; it is that plus the fuel used and other factors. There is no RPM curve, did you mean top of the horspower curve, or higher on the RPM scale? What is a speed curve? Reserve power behind the rotating shaft??? Maybe you should brush up on YOUR physics.

 

Was he stating that or was that a quote?

 

I think my ranger can run 17's in the quarter mile. So maybe it is better than a V10?

 

OK. I don't think it will run 17's in the quarter mile.lol

 

Sorry if it was a quote but someone needs to brush up.

 

I guess I should have made it more clear; that was a quote from the guy's article

 

Not to burden anybody with why the PSD is better, but I just saw this in another thread.

--------------------------------------------------------------------------------

I have 2003 F-250 V10. Few months back on long trip lost oil pressure and was away from my shop so towed it into Ford Dealership nearby. Had them diagnose while i continued home. They called a few days later and said that the truck ran great and never lost oil pressure for them. So they put a sending unit in it. Well last week was driving back home which is a 3 hour drive and i lost oil pressure once again but this time before i could shut it down it locked up. Now ive been told that ford has a tsb out about non ford filters comin apart and clogging oil passages any truth to that? I used wix filters and castrol oil. The truck only has 110,000 on it and i bought it used with 60,000 on it and i have not missed an oil change. Anybody have any thoughts this seems to be common with the V10, but cant get many clear answers as to why. I have not diagnosed it yet but am thinkin about just lookin for a rebuilt engine. Any help would be appreciated.

The PSD requires oil pressure to power the injectors. So low or no oil pressure means the engine shuts off before any damage can be done. Just a PRO for the PSD.

 

Unless, that is, you have a 6.4. In which case, the oil pressure sensor isn't even read by the PCM in any manner, and the hapless driver grinds up $15K worth of scrap iron..

 

Now go figure out which is easier to fix. A complete V10 motor, or the shop time for a diesel shop to figure out why you have no oil pressure and replace the HPOP

Seriously though, I mean, really? That's a PRO? Really?
