Do you want to be taken seriously or not? It's up to you.

jeeze, this thing still floundering around.....


still desktop racers only.....

No one wants to step up to prove it head to head !!!


sounds a lot like the "Global Wariming" fictional scenario to me


And there IS a definitive winner - always is - just depends on how it's reported and what is measured....

Wow....slpin pointed out something that nobody noticed before...although I don't think he noticed he did it.

I did the numbers, and 457 lb-ft @ 4750 RPMs isn't equivalent to 415 HP...it IS 415 HP. Meaning that something isn't right here, as that 415 would supersede the 362 peak HP.

So, looking at Ford's website, looks like some folks here have their numbers crossed.....

It is....

362 HP at 4750 RPMs
457 lb-ft at 3250 RPMs.

Peak torqe can NEVER, EVER come at a higher RPM than peak HP!!!!

Brain42...ever hear of cut and paste?

Ya, I saw that too. Just figured it was a harmless typo and didn't worry about it. But I was curious how long it would be until somebody pointed it out. This should be enough to carry the discussion another 2 pages!

One Big plus for the V-10 will be future parts and service. With the new 6.7 FORD in house Diesel coming and Navistar and Ford fighting, what do you think the future will be for getting parts for discontinued motor's (6.0/6.4) from a supllier who is being sued and hates FORD?. On the Other hand the V-10 has been and is still being made by FORD and is in everything from motorhomes to industrial water pumps.
As new & old techs get trained by FORD they will skip the 6.0/6.4 mess and focus on the new FORD 6.7. It protects FORD's name and gives them more of a chance to bash IH quality and get customer into the new 6.7 which will have tons of support and parts for.
The 6.0 and 6.4 will be the Dark years in fords diesel history. The V-10 will be a legend as we look back at FORD's gas motor history.
Time will tell.

Garbage truck??? So what kinda engine is under the hood of the tow truck that comes to get you when you blow a spark plug out?? That's right, a DIESEL....
M75 - hey guess who I am LMFAO!!!

I have a non turbo diesel, and the V10 has way more low end grunt.
BTW, my 160K v10 has never seen a tow truck.

Is 5,000 RPM bad for the V10? I run mine hard on hills, and it does not give me trouble.
I did run it to redline on a steep hill yesterday towing way, way to much and now the rear end needs to be replaced. Know i wish i had not tried to maintain speed up the hill and had just gone slow.
You diesel guys ever chew up a ring and pinion on a long, steep hill with a load?

What are you talking about?

No,it is not.
Generac Power Systems uses the 2V V10 in it's 150Kw commercial standby generators. They turn 3600 rpms constantly, and are rated for use at that RPM with a lifespan exceeding 3000 hours of runtime.
So,believe me... a periodic run for short term up to the factory maximum RPM will not hurt the engine.
3000 hours at 3600rpms is roughly equivalent to 180K miles of driving with OD locked out @ 60mph on your truck with a full load.

This is the kind of crappy advice that gets people in trouble. All use, no matter what type produces wear and tear. High rpm's will increase the rate of wear out on the engine and transmission. Sustained high rpm's will increase that rate dramatically. If you are interested to have your vehicle a long time without problems then I would avoid full throttle redline assaults up hills. Your engine doesn't like it, and your transmission definitely doesn't like it! How long do you expect an engine to last in a drag car? Please don't put your truck through a 5 minute drag race!

So how impressive is 3600 rpm for 3000 hours? Rule of thumb conversion between hours and road miles is to assume 45 mph average road speed. That means 3000 hours is 144,000 miles equivalent. Not very impressive is it? That's the kind of wear and tear high engine speed produces.

I'm surprised how many people are posting in the morning. I'm on vacation. What excuse does everybody else have? GET BACK TO WORK!!!

I disagree.

3,000 hours may very well be only 144,000 miles, but that also means 144,000 miles at 3,600 RPMs at high engine load...NOT cruising the freeway at 1,800 RPMs. Now, you V10 folks, when towing heavy how often are you over 3,000 RPMs? Just buy guessing, I'd say the only time you'd be using that kind of power is when pulling hills with lots o' weight. Which is what, over the lifespan of the truck? 5%? 10%? 25% for the very heaviest usage?

So, say a maximum of 25% of the engine's lifespan is spent at high RPMs under high load...the other 75% of the time the engine would not be working very hard. What's the lifespan of the engine for the other 75% of the time?

I'd wager that even if you were towing heavy over hills 50% of the time, which I doubt anyone actually does, the other 50% of engine life would be spent at much lower stress, which would put the usable life of the engine at well over 200,000 miles. How many trucks last much longer than that? Even worked hard, I believe the engine would last longer than the truck.

[bill11012]

I agree with that 100%
