2008 Ford Superduty

[calamaridog]

I thought I'd start a thread to post information you guys may have about the new Superduty.

The new 6.4 Powerstroke will make 350 hp and 650 ft. lbs. of torque. Full torque is available at 2,000 rpm. The motor will use dual stage turbos.

It seems they will offer fully loaded F450 trucks with 6100 lb. payload, 24,500 lb. towing capacity, and an integrated trailer brake controller.

The transmission has been upgraded and features a new torque converter design as well.

Here's an F250 4x2.

I saw one in person the other day. It was still on the back of transport truck. It was stiinking huge. This one was a dually and the hood was almost as high as the back is wide. Massive, massive, massive.

The majority of the body looks the same. It isn't supposed to be a total revamp, is it?

That grill is....uh.....ginormous....

It does seem that they have done a lot mechanically with them for this year, though.

Why people need 350hp and 650 ft-lb for a daily driver is beyond me. They should also offer a 4L 6cyl turbodiesel for people that aren't going to tow over 5000 lb. That would get economy into the low 20s. I'm certain the vast majority of F250-350s are not used for 5th wheel trailers. So in the meantime people get 15-18 mpg empty when they could get 22-23 with a smaller motor. And the failure rate of 6.0 Powerstrokes might have something to do with trying to squeeze >600 ft-lb out of the motor, though I could be totally wrong.

Ford and GM offered zero percent financing for awhile, and these vehicles' depreciation could be written-off on one's taxes as business expenses as they exceeded some GVWR threshold making them "work vehicles" or somesuch. So they sold like hotcakes because they were inexpensive to buy, not operate.

You will notice the headlights are actually at the bottom of the assembly and the bumper height is lower to make it more car friendly:littlefriend:

Unless there are some major changes with the Navstar diesels, I wouldn't own one unless you gave it to me- and then I’d sell it. Given Ford and Navstar's current tiff, it just reinforces that sentiment.

The 6.4 diesels in our Superduty based ambulances are complete junk- less than 40,000 miles on the three new trucks and they’ve all been in the shop multiple times for all manor of problems. All have been reflashed and other service bulletins; one is currently getting new heads. These are not old trucks yet they run horribly; our old 7.3 and 7.3 turbos are more reliable and they each have over 150,000 miles- one is closer to 200,000 (small county with limited funding and previously poor management).

The trucks we had in Iraq (I had an Excursion) were all having problems too although I'll grant that we were initially running them on JP8.

One good thing about buying a Ford you will get a piece of history, they are (because of poor engineering) about to go bankrupt.

I know several people with the 7.3 power stroke trucks and most get 18 on the low end. Several put chips in them that added OVER 100hp and they got better MPG. One buddy is claiming 22mpg empty on a F250 short bed 4x4 crew. He also ran from Atlanta to Alaska with a 39ft 5th wheel toy hauler camper with 4k of X-Ray machine and 3 ATV in its and was getting 15mpg on the plains.

The reason they didn't come that way stock is the transmissions can't handle the power if you are constantly hammering on it.

There is a fine line between HP and weight. You put too small of motor in something it has to work twice as hard to move it. My buddy with a 4cyl wrangler getting 11.5 mpg is proof seeing as how my 1988 454 Suburban with a TH400 (no overdrive) PULLING a 4Runner on a trailer with the AC on gets 10.5mpg.

MPG is not about engine displacement only. Its about how much power you need to keep it moving down the road and how hard that motor has to work to make that power. Smaller motors need to run at higher RPM so it may well use just as much fuel and air as a bigger motor running at lower RPMS.

I think you are referring to the 6.0L not 6.4L.

I agree on the 7.3L and the 2 you talk about above should go well over 350,000 miles before any major overhaul.

The reason they didn't come this way stock has more to with meeting Federal EPA regulations than what an automatic tranny can handle.

But its true…the slush box auto can’t handle 650 plus rear wheel foot-pound torque.
A ZF 6 speed, it can!

I bought a '99 F250 extended cab 4x4 SD new in '99. It now has over 125,000 miles mostly with a Lance 850 on it. I also haul a 27' HitchHiker II 5th wheel (nearly 12,000lbs loaded). Gas mileage averages 13.5 with cabover and 11 with 5th wheel.
The only things I have done are:
oil and filter every 3k
air filter no more than 5k
replace high pressure power steering hose at 90k
replace injectors at 100k (I don't think it needed it, but service man recommended it)
rear brake pads at 120k (front still at 40%)
passenger side latch at 50?K
tires at 55k and 120k
batteries at 122k
windshield every 3 years (Colorado winters are hard)
I am now using a 2003 Taco DC as my daily driver, but the F250 has been awesome.
We have travelled from Deadhorse, AK to Key West and from Nova Scotia to AZ with it with no major issues except the price of diesel has gone from $.50 less than regular gas to $.50 more and oil changes from $55 to $85.
I have never owned another vehicle this long. This one only because it is a diesel.
BUT, I will not replace it with another diesel. You will have to travel over 230,000 miles just to break even with initial cost, higher fuel and higher maintenance costs.

Someone should have taken this bet...:smiley_drive:
