I have a couple of "GT"s I'll race ya.
But seriously, I have smoked GTs, imports, etc. in my truck too. It is fun watching the ricer's little faces fill with sweet disappointment when they see my truck up there pulling away from them with the turbo whistle. Love it!

 

This thread is funny and actually has a lot of really good information in it, along with some pretty funny bantering. I just got my early 99 PSD. Coming from gas engines I am extremely impressed with it and love the diesel. May not buy another gasoline engine ever, but that is my opinion. I think probably gas and diesel, this is the only vehicle I have ever owned where I can throw as much in it, under, and at it as I can and it just laughs at me (figuratively speaking).

It seems obivous that ford designed the two engines in all model years to be closely competitive in power and (in most cases) reliability aspects. However, efficiency and longevity seems to be the difference to me.

I drove my truck back from Cabo San Lucas (Southern tip of the baja) in 3.25 tanks of fuel in 3 days with a 3 bedroom apartment in the back of it with the exception of 4 suitcases. I think it weighed somewhere around 1,000 lbs (not much, but not empty) If you haven't the driven highway 1 out of Mexico its brutal and dangerous with lots of narrow steep hills, hard breaking, nasty heat and dust, stop and go, and extremely aggressive driving. it got 17 mpg through that 1200 miles stretch and we were pushing 75 to 90 the whole way. The worst roads i have driven in Colorado Winters over any pass anywhere is cake compared to coming through Mexico.

From California I slowed down a bit and ran 70 to 85 and drove from LA to Denver in about 16 hours and got just under 18 mpg... again completely stock.

Now that I added a 6637 and hacked the muffler off (yet to get a full turbo back), I consistently get over 600 miles to a tank (33 gallons when i fill up usually) that has included significant amounts of highway, city, and on a couple tanks probably 50 to 100 miles four wheeling in low range (yes i take my 250 on jeep trails) I think when i... um... remove my cat, I could possibly make it to 700 miles to a tank.

Now towing, I don't have the heavy loads, but I have towed a pair of sea doos weighing in at about 5000 lbs for 650 miles and got about 15 mpg across the desert and then into Southern Colorado over Wolf Creek, La veta, and several other passes with speeds no other gasoline V8 can come even close (I have only driven the V10 in Uhauls, which I didn't enjoy but I don't think that counts)

I have also towed a toyota truck and my subaru on a Uhaul trailer, Each load coming in at 6000lbs with the bed completely loaded and have gotten 15 and 16 mpg over 100 miles or so of 70 mph.

I forgot to mention this truck also has 280,000 miles on it and I have put 12,000 on since May.

All I can say is I am super glad that I bought a diesel, even though I don't tow heavy loads. And the fuel costs more in Colorado by about 5 cents of premium, whats funny is in California when I was ther it was 5 cents below mid grade, In Utah it was cheaper than regular on my trip back, and from Colorado to Arizona last month, I was able to find it for less than $3 a gallon while gasloine went from 2.65 (Regular) to about $3.15 at the highest point. From what I can see diesel fuel prices are far more consistent as well.

and some pics just for fun... also because I am a picture fiend

on bald tires (weight is your friend sometimes )

Climbing a 6 ft. Ledge






and towing because thats what this thread appears to be about...



I am not saying I couldn't do all of this in a V10, but I am 99% sure I don't want too. I just can't imagine this thing in low range with 4.10's... All this tourque with 3.73's takes me from 6 to midnight in a hurry

Any way, sorry for the long winded response, Just wanted to give my .20 on the debate

EDIT: Oh yea, and the sound of a turbo diesel, especially opened up makes me happy

 

But with 650lb/ft of torque the xsmn will spin and spin...

 

01-03.....

 

In English please.

 

Torque(tractive force) is the only thing that matters, but not engine torque. Tractive force can come from either engine torque or gearing. That is why my manual 5.4 with a 23.45 final drive ratio in 1st (4.10 gear and 5.72 1st) will jerk the wheels out from under a 7.3 with an e4od and 11.15 final drive ratio in 1st(2.72 1st and 4.10 gear) even though it has much less engine torque.

 

I'll let the link explain it, but because of the large amount of torque available in the PSD, they don't need as many horsies...I can still spin that transmission, in turn, turning the rear wheels when the tc locks up...unlike the V10.

Howstuffworks "For towing, what's more important, horsepower or torque?"

 

Nice lookin truck plus I have those duratrac tires and I love them.

 

Nice pics and reps for using it like a truck

 

You need more power to move that much weight through the wind at the same speed, which requires more fuel, which requires more boost.

Very nicely written, but I disagree with some parts here. Engine speed is important, but turbos operate off of exhaust volume, velocity, and heat. With the throttle closed, even at high RPMs, manifold pressure is very low. Therefore you have much less air going through that engine, even if the RPMs are relatively high.

Most diesel engines are unthrottled, so there's no way to control air volume entering the engine. But even with that boost will still fluctuate with engine load and throttle position. My work truck would make 1-2 PSI of boost at cruising RPMs under no throttle, and as high as 35-41 PSI under full throttle...all at the same RPM!


Mine will. Does this make mine better?

The engine will spin up to full load and boost empty, I've done it numerous times and verified with a scangauge. Easy to duplicate on the highway with the trans in O/D, applying as much throttle as possible without forcing a downshift.

Very good point here! I drove a truck from September '07 to April of this year, and most of the time the throttle pedal was like an "on/off" switch. My 15L 1,750 ft-lb, 435 HP engine spent many long hours at full throttle. Far longer than it ever spent at part throttle.

Haha... Mike, Josh, and Bill got the details sorted out. Mike was driving!

 

Mine only goes up to 20 when I'm empty and floored, but if I'm running heavy it'll jump up to the 35psi range all the time. Dunno'...

 

I love them too!!

Thanks!

 

Thank you for clarifying that, you are correct, it is indeed volume that spins the compressor. A compressor can even spin faster at lower altitudes than higher ones, and in dense conditions. My point was that the engine speed directly affects the turbo rotation which dictates boost, but you are right in stating that it is about volume.

 

Come on! Now your just being silly! Bring your 15 second Super Duty out to the west coast sometime and I promise my 40 year old, low tech, pushrod Mustang will make you wish you'd never even seen a Mustang. Talking trash about truck vs truck is one thing, but truck vs car is just downright ignorant.

 

Man you guys only read what you want to read on this site and it's mainly gasser who can't read. I said in that post I know which one's to race since I did come from the mustang racing world, I know which ones to race and which ones not to. And I'm pretty sure I'm running mid 13's in the quarter mile which there are alot of mustangs out there even with mods that can't run those times.
