I will not beat any thing on a drag strip.
as I have said many times, a diesel will rip the crap out of my truck on the low end.
going 65 up a hill with a load and getting to the top, still at 65 is the way my truck will beat a diesel.

 

Come on down internet racer

only thing is , I have an issue when towing.... I forget it's back there

 

Where in TX is a hill long and steep enough to even cause a loaded pickup to loose speed, v10 or psd???

 

Transmountain highway, El Paso, Tx. Although it would start the turbo argument again.

 

haha, yeah, I so do not get the turbo arguement or the cylindar arguement. That is how they come stock! Though I do agree, let each run on the proper gears. Give the PSD 4.10 gears and the V10 4.30 and let em rip!

Everyone knows under the same setup like that, the diesel will outpull the V10. Then program, CAI and exhaust the V10, and program and exhaust the diesel, and it will destroy the V10. These are facts of life!

Then, let's fill them up full and see drives the farthest. It will be the diesel by at least 50 miles, probably more like 100 depending on the scenario.

Any V10s wanna roll up to Spokane, WA? I got a bone stock PSD for ya.

 

I can buy a lot of fuel for $6000. (facts of life and all)

 

I was thinking about this last night, To me, the main reason the v10 is better, is the reliability issue. And the price.

If the new psd becomes as reliable as the gas engines, I would probably choose a diesel next time. Especially if the mileage can improve

 

Provided it also:
1: Came down in option price
2: Became cheaper to repair (parts & labor)
3: Became better at short trips
4: Smelled better
5: Ran quieter
6: Was produced long enough to prove itself

Then I might consider it.

Okay, Bill, I have time to figure this out now.

My 265/70/17 tires are 31.7" tall, which makes for a circumference of 8.29 feet. At 70 MPH they would be turning 743 RPMs.

4th gear on my TorqShift is direct drive, 1.00:1 ratio, which leaves the only gear reduction present at this gear would be my 3.73:1 rear end. Meaning the engine would be turning 2,771 RPMs at this speed and gear. Assuming 625 lb-ft at that RPM, would leave:

625 x 3.73 = 2331 lb-ft applied to the wheels. Adjust that for the 15.85" radius wheels, you'd have 1765 lbs of force pulling the truck and trailer up the hill.

Also, 625 lb-ft @2771 RPMs would equal 330 HP.

Now we do yours. For the sake of simplicity, I'm gonna use the same tire size for your van. Also, because I can't get specs as far back as 1999 on FTE, I'm gonna use the 2000 PI-head V10 for HP and torque specs.

So, 743 RPMs at 70 mph. With your 1.55 2nd gear and 3.73 rear end, that would put you at 4294 RPMs at 70 MPH. Which is just perfect for your engine, as your peak HP is supposed to be at 4250 RPMs. Also makes it easy to calculate torque.

305 HP @ 4250

HP = (TQ x RPM)/5252

Therefore, at that RPM you're making 377 lb-ft of torque. Remember that this is revving well past your torque peak, so this WILL be less than peak torque...but it's still pulling harder 'cuz of RPMs.

So, 377 lb-ft x 1.55 x 3.73 = 2180 lb-ft at the wheels.

Adjust that for tire diameter and you have 1651 lbs of force pushing the van and trailer up the hill.


In summary:
(disclaimer:All values here are ignoring driveline loss, which we can assume is reasonably close between transmissions, therefore they wouldn't change the outcome here. Also, I did A LOT of math on the side here not mentioned in this thread, as it would take lots more room.)

1765 lbs trumps 1651 lbs. Every time. This is because, regardless of gearing, I am pushing 330 HP at that RPM to your 305(IF you had a 2000 MY!).

See?

 

finnaly someone got the math right. I knew it didnt look right, and ive been tryin for days to figure it out, but i just wasnt smart enough.lol

 

I like my 5.4 liter3v setup in signature...

I tow what many consider heavy 12500 and run with my PSD buddies to the track.
My rig has gone 70 to 75/80 towing. I run right with the 6.0 PSD but the older 7.3 liters, of 1997 have more power then myself. Mostly on hills or hard long pulls.

Either way for my towing needs 6500 to 12500 LBS, my F250 is a perfect match.

 

okay, number 1) lets do some math, I get about 17 unloaded and 10 with my toy hauler, both hand calculated. The v10 I have been around would get 12 unloaded and about 7 with my toy hauler from what I understand. So on 15,000 miles a year, say 7,500 loaded and 7,500 unloaded, yesterday diesel was at 2.51 and premium was 3.00. Cheap stuff was 2.81.

So, diesel would cost $2,990, cheap gas would be $4,767, and premium would be $5,089. At about $2,000 per year, 3.5 years the diesel would be paid off, if both were bought new, assuming $7,000 premium. When used, the premium is closer to $3,000, so the payoff is about 1.5 years. This is not taking into account additional time when you have to fuel up more often if driving for commercial purposes.

2) Agree, but buy a warranty, which there is not much of a premium and you do not have to worry about it.

3) Neither truck is great at short trips, but who really just drives 3 miles at a time and that is it? So if you are that small majority, I could vote for the V10.

4) I have a 2006 6.0 and there is ZERO smell. Unless you program it and kill the exhaust, the 7.3 doesn't smell. So this is mute.

5) When running synthetic, mine is fairly quiet, though at a drive thru, I still turn the engine off, but this is so minor, in fact I kind of like the noise. I do not hear it with the windows up and when towing, it is much quieter when pulling than the V10.

6) This is a Ford/International issue and with the 6.0 they created a great engine with a great SOP feel, but it requires some real particular maintenance. The 6.4 needs to be programmed to see how great the engine is, the particulate matter burner is junk and kills the mpg.

Okay, so I just blew almost all your points out of the water!!!! hahaha!

 

Dude, you do not pull 12,500 with a 5.4 at 80 mph. My 6.0 Chevy gas engine could do that, but get 4 mpg. And PSD tears a 5.4 up any day of the week, even if 2 injectors were blown!!!!

 

My post is clear Dude... LOL

And when I get off work late, and gotta get there and be set for morning drivers meetings, and rules updates for that particuler race (they call it the war room) I really dont care about MPG. LOL

My mustang uses 5 gallons for two 1/4 mile passes. My buddies top fuel car running 90% Nitro methane usses 55 gallons a day 3 passes.

My MPG not towing is 13.86 towing my 6500lbs camper its around 12 to 12.5 and my race trailer normal driving it is about 10 or so.

I could have bought any truck I wanted in 06. Cash wasnt the issue for this driveline. It was maintenece. I dont want high Maintenence, and I am very impetient. When I leave to go somewhere far, I want to get there.
This driveline is perfect, It does what my buddies 6.0 PSD does. Its like the same engine only his blows black smoke and smells when idleing.

The 7.3 is the engine to have though... 1997 to pre 2002


You got a Honda... what do you know... HU???? LOL

 

Haha, I guess I am the only one dumb enough to respond to this. A properly maintained 6.0 will destroy a 7.3, the turbo is the 6.0 is so far advanced it is sick. The boost it pulls at low rpms is incredible. So yes the 7.3 is stout, but the 6.0 pulls harder than the 7.3. It shows your lack of knowledge by saying a 1997 7.3 can outpull my 6.0, unless it is programmed.

And my 6.0 does not smell at all in any way. Now if I program it to a dirty tune, then yeah, it can smell. But that doesn't make sense.

Your mpg numbers are BS unless your speedo is way off or you did some serious work to your 5.4. You will not get 10 mpg towing 12.5k at 75 mph.

The maintenance thing, you got me there. The 6.0 is a PITA when it comes to maintenance and is very particular.

And no Honda in my driveway, my wife's car is a 2006 Impala SS that rocks most stock cars, even most stock Mustangs.
