I think that is the allure of this thread. It's like a cage fight with two fighters that have been lobotomized, they just won't stop.

Oh good, another spectator! I saved you a seat.

 

Vail Pass. I grew up in California...None of the passes out there are like the ones we have out here. Deal with it. I picked a very civilized, always traveled pass so the only thing that would get hurt would be your feelings. (Which they obviously are)

 

If I had a 3V I would take you up on that.
My V10 is a 2V. Get a stock PSD of the same age and I will.

 

That's like doing the Camaro vs Mustang wars...Every other year, the other was faster. However, since 06, the PSD's have evolved every year while the V10...well....remained the V10.

 

Why fix whats not broken?

 

I think they merely realized there was nothing else that could be done...Any other tweaks and the mileage would be like 5/10 and towing would be like the M1A2 main battle tank....3 gallons per mile.

 

I'd tell everyone that since I doubled up on the Diesel Kleen in my tank, I'm getting 20mpg heading down to Denver, and coming back up at 70mph, but none of the V10 owners would believe it, so I won't. I will say that the mileage difference between doing 65 and 70 is nil.

 

No, you picked a road with an elevation higher than 99 percent of the roads in america because you know the psd will have a huge advantage there. A v10 on vail pass has the same hp as a 1996 4.6 at my elevation. We have all agreed that virtually any psd will win on a road at that elevation. Tom had to slow down against a 2v v10 with a 3.73 and 4 speed. I didn't see him slowing down against johnny even though johnny had a lot more weight.

 

Josh, I hate to say it, but you're fighting a losing battle. You're using logic and reason on someone hell-bent on creating chaos and ONLY on creating chaos. Abandon ship if you have any hope of survival...

 

No the v10 guys think theirs will outpull a v10 based on math and dictionaries. Psd guys think they will outpull a v10 based on actual test results.

And until someone with a psd goes to Texas or Virginia we get to hear Josh and Bill throw out theory and make excuses.

Sorry for putting fact into it. Hahaha

 

it always amazes me that this thread constantly has a new post, I've had a 7.3 which i loved, and i have a 6.8 which i love, but i hate the mileage. the 6.8 can easily pull anything that my 7.3 would when it was stock, but not as efficiently. If you wanna go fast in a hurry, then you need a bunch of hp, and torque is not as important, if you want to get up to speed and STAY at speed with whatever amound of load you brought along, then you need torque and hp is not as important, my daily driver is a 2008 KW t660 with a cat c15 in it, its spec'd at 435/1850. If horsepower was the end all be all then big trucks would have 1500hp nitro burning blower motors in them, they would pull just as much as the 400hp big torque diesel does, and would accelerate like mad, but without much efficiency. the 6.8 has its merits, it can be fueled at any station, it doesnt care how cold it is or if it was plugged in overnight when its time to start it, oil changes are cheaper, it is much quieter than any diesel of its vintage, and it is buttery smooth, it isnt loud and smelly (as some people called my 7.3) and when it has a load on it with a nice exhaust the exhaust note can be almost musical, but it gets craptastic mileage. The PSD has its merits, efficient, SUPER easy to make gobs of power, very durable, at the expense of higher cost per gallon for fuel, higher maintenance cost, and the noise and the higher initial cost. THERE IS NO ONE BEST ENGINE!!!!!!!!!!! It entirely depends on your intended use and needs people!!!!! what might be the best choice for one guy is not the best for the next guy, thats why they build them with more than one option available!!!!!!!!

 

I see nothing has changed here....

 

Because the PSD had to evolve to deal with emissions changes. And I'm sorry, but '06 wasn't the change from the 7.3 to the 6.0 (because of emissions), and the 6.4 came out in 2008. Not 2006.

--

The whoever asked about the F650/750, it's 2012 that Ford is introducing the V10 with the 6-speed in those trucks. It remains in the F450/550 chassis cab.

Also, the 6.2 came out to replace the 5.4, and was "close enough" to the V10 that it became ridiculous to produce two different engines in one platform. With the 6-speed, it's gas mileage is darn good.

It will be interesting to see what happens when the MPG argument is moot between the 6.7 and the 6.2

 

Diesels are being saddled with emissions much like gas engines have been for years. As you said, when diesel MPG drops to what gas MPG is, and with little difference in performance, it will likely boil down to cost of fuel. When that happens, and it surely will, gas will be the only sensible option.

Imagine if Ford were to put a turbo on the 6.2.

 

We are about to see what it does to a 3.5L V6... well over 400 hp and 400 ft-lb torque peaking between 2000 and 2500 RPM and ability to tow 11,300 lbs.

A turbo 6.2L would be beastly.
