I think there was something wrong with your 7.3 IDI if your 5.4 has more power....
I've driven a few 7.3L and 6.9L pre-powerstroke engines. I'd have to agree, the 3V 5.4 is more powerful.
The old engines were torque monsters, but not much horsepower. You could pull a load far exceeding the ability of the 5.4L, but you were not going to win any drag races.
The old IDI engines reminded me of the semi trucks I would see as a kid. They could pull 80,000 pounds but would crawl up the shoulder at about 15 MPH on the mountain passes of the west. Lots of torque but not a lot of horsepower.
Alright guys, this is where I need the emotional support of my fellow Triton Powered Super Duty owners. I am involved in a heated debate with a friend of mine, who lit a fire under my rear making the blanket statement that the 5.4L SD's are UNDERPOWERED, especially in comparison to the General Motors Vortec 5300 and 6000 series small block.
Now I for one will stand behind my Triton 5.4 until the little engine that can does me wrong. In fact, I prefer my 5.4 over the general's pushrod engines. They may go fast (a lot faster), but I feel they are not as suited for all-around truck applications as the mod motor in these SD's.
Does anybody have a horsepower/ torque curve for the 5.4 and any testimony/ opinions regarding our debate?
I used my 04 250 with the 5.4 to uproot a tree that was almost 30 ft. tall and a foot in diameter. And it has 130k on it. *low rumble*
Pulled a uhaul auto transport trailer with a 2008 ranger extracab 4x4 home 200 miles yesterday after haulin it through the city to satisfy the wifeys shoppin bug. Not fast but didn't feel like it was workin too hard, except from stops to get going. She my sd! love it.
if i could find my dyno sheet ide show you,350 kw at the wheels when first tuned then summer came and i could hear it pinging abit so had detuned back to 335 kw at the wheels.very aggressive power curve.motor basically standard except for the turbo.n/a had it running 218.9 kw at the wheels.aussie 03 5.4 triton 3v
I once had a new 2004 2500 with the 6.0, my father has a 2000 f350 with the v10 we were coming up over the cascades pulling very similar trailers and he had much more go then I did. I know that the 6.8 is much more engine then the 6.0 but the way he was able to maintain speed in a heavier truck with maybe a little hevier trailer left me feeling a little inadiquate. I think that they are all good motors but I would prefer the Ford not so much as for the engine but the truck that wraps around it.
