Just an FYI,Ford's Michigan Proving Grounds is over 800ft elevation.
That's not 4000+ft,but it's damned sure not sea level either.

Really....so I bet you think the same for a 6oh too

 

Oh yeah, well at least I don't have to look at my tach to know my engine's running!

 

It's never a problem during the winter but during the summer, I get stuck behind more V10's than I can count. The funny thing is, that the V10's and the 5.4's do about the same going up the hill because the V10 dude has a bigger trailer.

I don't know if those trucks are modified either. I do know that my truck is stock. My point is not to disparage the V10. I think it is an outstanding engine and if I lived in Houston and never traveled to high country, I'd own one. My point is that the psd and V10 are very close in terms in performance at sea level. At high elevation, the difference becomes significant.

I don't race up short hills at the proving grounds either, but thanks for the info just in case I ever do.

 

Looks like the V10 is a better machine @1500' & lower...PSD sounds like it is working more, but the V10 has a 2% edge

 

I'll see your 2% edge with my current 7% lower fuel cost. I'll arbitrarily add a 2% fudge factor for also having better fuel economy but then take it away because the 6.4L sucks at that. So far I'm ahead 5%, but then I'll take away 7% because of the ridiculously high maintenance costs for the diesel (seriously, 15qts of oil is not cheap to buy!). Now the gasser is ahead by 2%. But wait, a diesel will usually outlast a gas engine so I'll give 2% to the diesel on that one. So that leaves 0% edge.

By my calculation it's a push!

When all is said and done, everybody owns a Super Duty and is a winner in my book!

 

I agree. It looks like the thread is picking up steam again.

 

Ever heard a V10 that was strait piped?
It never has that problem...

 

Yes I do.

 

PSD / Gasser,,, ahhh,,, same shi'p' different pile. I bought my Truck because it fit my Magellan "Triton" 2000.

Rick...

 

so how big is your trailer and what is the weight

 

2X Bill I have yet to see one of your famous loads on your Van.

Post up some pict of you loads guy's

 

I do not have the third gen 3V V10,so You will out pull me.
I have the first gen V10 that ran from 97-99 with 265HP.
A 3V would out pull you, no question.

22K GCW is the heaviest I have ever been.




I need a bigger trailer, I loaded it to the bump stops and then started loading the back of the Van up. I stopped when it hit bump stops.

I only have axles for 17K GCW, so that is about the heaviest I will ever load it.

bronco, I have only taken pics on a few, but here you go.

 

Thats your ride? Looks like a Mormon Mover to me! lol. I'd like to see you put 1500 worth of mods like I did and **** out 600hp and 1100lbs of torque. Say what you want about stock, I'm talking about what we got and what our current situations will do. I'd leave you so far behind you'd be thinking your Mormon Mover wasn't even started. Just kidding. I like the Maroon its pretty.

Nothing like a good old fashioned "my dicks bigger than yours" war!

My 08 6.4 is the first diesel I owned and the only reason I bought it was because I was going to buy a 08 V10 and I actualy signed the papers and took it home. I went straight home and put my 10k trailer on it and took it for a ride in the good old Pacific Northwest and it was a joke up hill. Took it back and told the guys I didn't want it. I had a 3day period to break contract. They let me take a 6.4 home before I completly backed out of the sale. Loaded it up stock and it was a night and day diffrence going up a hill. I stuck with the PSD. I was actualy excited about my new truck, alot better than going home dissapointed after $45K.

The 7mpg was also a nice little treat on the V10 too. With my tuner I now get 14 towing/ 16city/ 24hwy. Thats almost exactly double the gas the V10 was getting. Nice truck but I'd rather pay more anyday for that diesel upgrade when your wanting a truck to perform like it aint gasping for air when towing.

Might wanna look into some stiffer leaf springs, or an add-a-leaf. Maybe some air bags. Thats some nasty sag you got there bro. Well at least its a Ford!

 

Did you happen to check your highway mileage before you put the tuner on? Also, what kind of tuner do you have?
