The 5.9 very comparible in street form as far as performance. However, it has proved that it can be tuned to smoke a lot of performance sports cars which the PSD light duty engine it is not capable of handing the level of performance the cummings can generate]
Another thing, I6 vs V8. 25% less moving parts]
cummins guys always use this one, having "25% less moving parts" does not ]necessarily mean that the engine is better
if the engine pushes the the same or more torque and HP with 25% less moving parts it means it will get better mileage which means its a better engine for the dollar, especially in the case of the cummins where it has been proven to last longer
sorry to go off topic a bit but i have to say this. rancherman84
, isuzu has been making diesles whith aluminum and alloy heads for 20+ years whith the 2.2L and the 2.8L TD. How many isuzus do you see on the side of the road broken down, that alone should atest to the fact that Isuzu knows what its doing.
my truck is twice as old as me!
Big question is, who will eventually win in the hp and tq war. Cummins just retunes to up the HP. International redesigns.
I'll put my money on the Cummins. We have already seen it run 10.8 in the 1/4 mile. That was the 12 valve engine at that. Wonder what kind of HP and TQ it takes to do that?
As far as inline vs V-8. Take a look at the majority of large CI industrial diesels. What configuration are they?
Pop the hood on the PSD and pop a hood on the Dodge with a Cummins. Tell me again the advantages of the V-8 vs I6.
The only thing PSD has going for right now is that the Cummins, Dodge relationship maybe coming to an end after 5 years. Look for ford to move in and start using the Cummins, then your questions will be answered.
what that picture fails to mention is that ford rod is made of powdered sintered metal and is stronger than a forging, so its high tensile strenght than the cummins and has quite a bit less rotating mass, I havent heard of any rod issues........everyone I know with a 7.3 psd loves it and dont know and 6.0 owners and dont know any cummins owners
Im sure the 6.0 is less heavy duty than the 7.3 and i wonder what the 7.3 rod looks like, got any pics? does the 6.0 have a longer stroke than a straight 6 cummins? the rod sure is longer
Actually the bottom end in 6.0's are stronger than its 7.3L predecessor. The engineer showed me how technology has improved the metals strength and quality. I even asked him what he thought about the Cummins, he said it was great for larger trucks (Medium duty, F-650-750, C6500-8500), but for pickups he said once they get the 6.0L perfected, it would be the best pickup engine, being that its lighter and better suited for highway driving without the fear of being overrun by other vehicles.
