Gas vs PSD
That's whats really being argued. The engine only begins the equation, it doesn't end it. Yes, I could use a pneumatic impact gun and outpull your V10. All it needs is the right gear reduction. It might only pull the load @ 12 inches per hour, but it will out pull you.

The V10s peak HP & TQ is right around 4500rpm. It's ok till about 5K and goes right down the toilet after that. That curve starts out at pretty much nothing and doesn't get moving till about 2.5K rpm or so.
The diesels torque is available almost as soon as you step on the pedal and stays pretty flat almost all the way through it's power band, which tops out at around 3K rpm - 3.5K rpm.
What this means in the real world is that the diesel is going to pull stronger from a standstill than the gasser will, unless you are willing to run WOT everytime you step on the gas. Since no one with any sense does, the diesel is going to out pull you unitll you start building up some rpm, and speed.
In the real world again the diesel is going to be towing down the highway at legal speeds pretty much right smack in the middle of its peak power band, while the V10 is going to be a good couple K rpm below it. Of course you could always drop a gear and crank up your rpm, maintain your speed and scream along at 4500 rpm. That would be fun. Or you could stay in high gear increase, your speed till you're at 4500 rpm, and get arrested for doing 30 over the speed limit. Numbers just pulled out of my butt since I don't feel like doing the calculations which require your final drive ratio in your transmission, the gear ratio in your axle, and the diameter of your tires. ALL of which determine who pulls better, not just the engine.
The rpm argument doesn't hold up. The gasser NEEDS 4500 rpm to makes it power. The diesel doesn't. It doesn't make the gasser better able to pull a hill. You're going to drop a gear to get that rpm, and drop your top speed in the process. The diesel will do the same thing. Drop a gear, stay in his power band (at much lower rpm) and do the same thing. BOTH of them depend heavily on gearing, both in the transmission and rear end, to do their jobs. The difference is the diesel gets its peak performance at a much more comfortable and equipment friendly rpm then the gas engine.
If the gas engine was really the better power package for every day towing then every semi truck on the planet would be sporting a giant gas engine under the hood.
Bah. This really is a stupid argument anyway. There are so many variables involved you can go back and forth all day. "His 3V V10 with 4.30s will out pull your 6.4 all day". "Ah, but my 6.4 with 4.88s will tear you in two"! On and on...
My PSD will eat ANY stock V10 on the planet. Period.
Like my new signature, Bill?
Actually most diesels are at a disadvantage in sled pulls. Since traction is not all that great performance in those events rely HEAVILY on wheel speed, something diesels are not incredibly good at. Gas engines on the other hand can be made to crank out some rpm relatively easy. Again, lots of variables. Diesels can be made to perform but gassers are easier and cheaper.
Bill, show me a stock F250 with a V10 rated for 650lb/ft of torque and I'll leave you alone.
Not sure who the "him" is, but what I was commenting on was the, believability if you will, of someones claim of using his V10 to trounce varies diesels at a truck pull.

I give them that.
I get what you're saying but that logic can apply to just about any vehicle. If you're only going to push your mustang out...yadayadaya, then spending the money makes no sense. Buy a bike or take a bus.
Diesel makes sense when you are going to tow and tow heavy. Makes MOST sense when you are going to tow heavy and tow a lot. If you don't intend to then from a financial stand point it doesn't make any sense. The fuel savings (if any) over gas don't add up. Maintenance savings don't add up. The fact is the average driver will not drive enough, haul heavy enough, or even own the vehicle LONG enough for any diesel savings factors to be an issue. Not even the vaunted longevity of diesel engines come into play for the average user. People just don't keep vehicles long enough for it to be a factor. The average person keeps their vehicle an average of 7 years before swapping it out. Even if a person put on 24,000 miles a year, double the average, most gassers are still doing quite well at that mileage.
I bought a V10 because I knew I would only be an occasional tower and would not tow all that heavy BUT, on a couple occasions I towed heavy enough to know that the V10 is not the engine for the job if your are going to do it consistently.
I bought an F-450 because my next purchase will be a fifth wheel toy hauler that will have an average rolling weight of around 14-15K, but has a GVWR of 18K. I want a truck that I know can haul that max, flat or uphill, and do it at a comfortable rpm which means a more comfortable me and passengers. The V10 is NOT that engine no matter how you want to spin it.
I mentioned earlier on, I have a V10, a 6.0, and now a 6.4. The diesels are by FAR the better towing package.
Don't know why Ford is making such a big deal of it. Or maybe they sell V10 below cost to get rid of spark spitters?
30 over will get you in all kinds of trouble. Thats why I try to keep it to 19 over or less.

Name one thing that a PSD can pull that a V10 can't.
