At what speed?

If your going to mod it then of course you can make it beat a V10.
Stock vs stock you don't have a chance vs even the NPI 2V.

If your going to mod your truck then I can just mod mine and still out pull you.

 

First off, I think you have made up your mind which is the better of the two.... But the 7.3L will all around win based on your description.

They have a track record of excelent reliability, great power and fuel economy and are known to last 500,000 plus with good maintanance.
I have talked to 7.3L owners with 7-800k on the original motors.

Now the 6.0, that is up for debate (for the 6.0 guys, no I do not hate 6.0L)

My choice of engines:

1. 7.3L V8 Diesel
2. 6.0L V8 Diesel
3. 6.8L V10 Gas

 

So, how much will it cost you to mod yours to the point to outpull mine at the level I listed? (and still have a reliable DD) I'll have roughly 2k in mods.

P.S. I can always mod mine to be one step ahead of your gasser

 

This is in your 99 F450 dump truck?!!!! I have never seen a dash like this in a Ford truck.

 

Bill, again you say something I agree with...

Which one costs less to drive? PSD
Less likely to break down? 2003-2007 V10, rest of years, equal
Pulls harder? PSD
Lasts longer? PSD

Your point?

 

I think it's either a Beamer or a Mercedes, I can't remember which...

I'll bet he can't do more than 85 ish in his F-450.

 

Me and him got into my DDs 4.6 ( the V10s little brother) vs his mecedes.

I can make the same power for the same amount of money. You throw anouther grand in and I can too.

 

Tii... having cruise control set at 130 in Ford truck would be nice

 

Welll, just a point of order, but the real "debate" started after "my V10 will out pull your PSD blah blah blah. Which one is better I think is somewhat relative and depends on which engine, which model year, etc etc you happen to be discussing at any given time.



Makes perfect sense. I have an '01 V10 Ex and it did a pretty decent job towing my 33' TT, but some of those W. VA hills would make the ol' girl scream. I at least was pretty much at my comfort limits. Super(duty) Man to the rescue!


Hey, he started it! ()


According to Bill though, that isn't pushing the motor. It'll run 5-6k rpm all day long from birth till the day it dies a gazillion miles later, remember?

All kidding aside, I agree that there are cases where the V10, or whatever gasser actually, makes more sense in every aspect than buying into a diesel. When I had my TT it was certainly adequate. There were some hills that definitely made it work, but they were just a small percentage of the overall towing miles. I could live with it. But, that was with an 8-9K trailer. My new fifth goes 16.5 ready to roll and there is no way on gods (or Bills) great earth that V10 (or the 3V IMO) is pulling that load up that W. VA hill without SCREAMING through the process. Not for me thanks. That kind of load makes hills that used to be moderate much more significant, and really serious hills way more, well, serious.

As a side, I used to get about 8-9 MPG avg towing the TT. I get about the same with the 6.4 pulling the 16.5K fifth wheel.


(PS. Would some of you guys PLEASE learn how to re-size pictures!)

 

Without a doubt I agree with you here.

But that much weight on any steep hill will send ANY engine screaming towards it's HP peak. On a PSD that happens to be ~2,500-3,000 RPMs. A V10 would be 4,000-5,000 RPMs.

Each engine will be in the upper end of it's rev range. I just don't see the difference.

Fuel economy certainly is a benefit of the diesel, but it comes at a cost. For me it was $7,895. I could have bought a LOT of gas for that...

 

That is about what I paid for my whole truck 4 years ago.
I still would like to explore the "outpull" statements here.
With my no-mods 7.3 PS, 4.88 rear differential and 19.5" duallies I don't care what Bill has. He can modify his V10 all he wants -when I put 8,000 lb on my bed for better traction -he will go backwards

 

I have to say that this is by far the most entertaining thread this forum has to offer! To the man who started this here is one imaginary beer for the great reading material.

 

I am happy to see you got the spirit on your first reply.
Welcome to the forum and what you drive?

 

I don't want a tug of war, I want to race up a grade.

We both scale at the same weight and then start at the bottom of a grade. Dead stop, roll or highway speed at the start, your call.
First one to the top wins.

I'll wait up for you when you get there.

 

Tom,

I think that is part of the issue...some feel reving the SOHC V10 up to 4000+ RPMs equates to "struggling" whereas reving a PSD to 3000 RPMs not "struggling"...WHY is that is the real question.

The simple nature of a SOHC motor demands that RPMs be made to tap the HP the engine is able to make...turning RPMs in a SOHC motor is NOT struggling but simply working in the designed powerband...couple that with rear end gears and that is how you move loads.

A 1999 7.3L unmodded PSD makes how much HP?... 235hp at 2750 RPMs...don't you think "gearing" has something to do with moving a load up a grade?

A 1999 V10 makes how much HP?...275hp at 4250 RPMs...and guess what?...gearing plays a part of moving the load too...

A 2011 6.7L PSD makes how much HP?...400hp at 2800 RPMs...and gearing STILL plays a part in moving that load...

A 2011 6.2L gasser makes how much HP?...385 at a whopping 5500 RPMs...and guess what..GEARING STILL plays a huge part in moving that load too!!!

Working at the PEAK HP is NOT struggling...it is working WHERE the DESIGNERS intended to make PEAK HP...SIMPLE...and you know what...look at the numbers...a PSD makes its peak at a DIFFERENT RPM that's all...DIFFERENT RPM but SAME result...move the load UP the hill effectively!!!

I've towed I-64 thru West Virginia...there are more than a few 7% grades that are like 5 miles long...I've tugged those hills with my 9000# TT behind my V10...I was able to run them at 70mph in 3rd gear at 3200 RPMs...BUT lose momentum and I'm in 2nd gear running 55-60 at 4000+ RPMs...gears do the work...that's the whole idea...right?

As far as how many gallons of fuel I burn...well you can do the math...20,000 miles divided by 8mpg multipled by the very volatile gasoline prices...simple math...

When I was looking at a 2005 Ex...they wanted $10K MORE for a 6.oH PSD...I am still thousands ahead of buying that PSD...I've put 36,000 miles on my Ex in the last 5 years with well over 20,000 being TOWING miles of those...if you do the math on mpgs versus fuel price...I've still got many thousands to go before breaking even...

I've talked with many people in the 35 states I've pulled my camper too and I can tell you that none of the diesel driving people I talk to face to face around a campfire get near the MPG's that are reported on the internet...go figure...the non-internet mpgs when you figure the price per gallon offset make the V10 to PSD price per gallon darn near equal.

WIND resistance is a BIG factor snowseeker...your TT is a LOW profile TT...try towing my HIGH profile TT and see what MPG's you get...and then throw in a 20+mph HEAD wind and see what happens...my 8mpgs AVERAGE factors in tail winds, head winds, up hill, down hill, flat terrain, you name it...8 solid MPGs towing thru 35 states thus far...after July...it will be 39 states my Ex has been thru...how many people have that kind of real world data and not internet nads behind the computer making up stories?

BTW...here's a HIGH profile TT...look how much taller my dual slide TT is over your no slide TT...that extra HEIGHT adds serious wind resistance and wind resistance at highway speeds alone reduces MPGs and then throw in a head wind and well...frankly the mpgs will suffer I don't care WHAT motor you have...tow enough all over the country and experience enough weather and terrain...and well...as they say...life happens!



The only FACTS I know are the one's I have for myself and basing my decisions on FACTS alone has proven to be pretty beneficial and economical thus far in the 35 states I've towed my camper thru...I'm not one to believe some of the fantasies on the internet...I'm sure others believe what I report as FACTS are fantasy...and that's cool...why don't you hitch up and come for a 4500 mile pull thru the Rockies this coming July and we'll make more FACTS...

Joe.
