All they had to do was drive out here to Colorado. We had a lot of V10's on the dealer lots. My dealer shipped them off to MO though.

 

Lol...the 7.3's are loud...I'll give you that. My 6.4 goes through the drive thru, no problem. It sounds more like a 5.4 with bad cam phazers.

 

I think I am failing in love with V10.
There is a guy who has one in the mountains with blown plug and he is willing to pay good money for somebody with trailer and RELIABLE tow vehicle to bring the truck home.
Perfect job for my lowboy trailer and PS Superduty.
I am going to be rich

 

Well, you answered your own question then. There was a waiting list in MO.

 

You can drive it with a blown plug.

The reason that diesel can get that much weight moving so quickly is because of the tranny has so many gears. Put a 4/5 speed tranny behind it and see how quickly it gets 80k lbs moving. Put the same tranny that is in your semi behind the v10 and it will get the weight moving a lot easier than you think.

Actually the only number that matters is tractive force, which can be generated from either engine torque, gearing or a combination of the two.

 

Ok gearing is a good point, BUT lets take that engine and either the V10 or my 7.3 power stroke. put an 80k load behind them get all of them moving to 60mph and then put them into a gear that is a 1:1 ratio (top gear on the old non overdrive transmissions).

All 3 engines will hold that speed probably if your have the gearing to put them into their respective power bands (going to be fair and not try and say that the V10 has to do this at 1200rpm) NOW let them hit a 2% grade... how about 3 or 4% what do you think is going to happen? The engines with lower torque numbers are going to fall on thier face even IF they have higher hp numbers.

It's really pretty basic physics, torque is the force that moves things with an engine. HP is a mathematical equation trying to equate torque and rpms to a number people understand, but is usually miss understood.

I am not even saying in any of this that the diesel is better then the V10 all I am sayin gis the HP number doesn't tell you how much work that engine can do.

Another example the race engine I built for my ranger, 926hp but I dang sure don't think it would even hold a candle to even the sickest of V10s (or even the 5.4 for that matter ) when it came to pulling. Now out and out acceleration? would walk all over every truck here. (BTW that engine also had almost 850lbs/ft of tq but it was at an unusable range for towing, it came out at just under 6k rpms)

I know how about a new 2010 4.6 mustang? rated at 315hp from the factory. Does ANYONE on here honestly believe it will outpull my 2000 7.3psd with it's factory racted 235hp, or even come close to your V10? Or how about the 2010 Lincoln MKS? it has 435hp, do you believe it will outpull your V10 or even an old IDI 7.3 for that matter?

Making up gear ratio's doesn't help the discussion either. I could gear a B&S to pull a frieght train but that doesn't prove anything.

 

The first part of your test would be impossible to do though. You can't have a v10 and a psd and your semi all with a 1 to 1 gear ratio, doing the same speed AND all three be in their power band. With the same ratios in the gearing and doing the same speed, the v10 is going to be forced to be below 2,000 rpm to stay even with your semi. That's why we are saying the v10 needs to be a gear or two lower and turning more rpms to do the same job.

The second part of your test, where you put them on a hill. 325 hp is 325 hp whether you make it at 1,200 rpms or 3,800 rpms. My 5.4 won't climb a hill at 2,000 rpms like my 7.3 will, but if I downshift to get it in its powerband it will smoke my 7.3. To see how important hp is, just look at your own 7.3. Does it pull harder at 2,000 rpms or at 3,000? It has more tq at 2,000, but it has more hp at 3,000(where it pulls harder).

That depends on what you mean by outpull. I will agree that the 3v 4.6 will outpull a 2v v10, 5.4 or a 7.3 if it is geared right if you are simply talking about acceleration. Tom took a 3v 4.6 with a 6 speed tranny and outpulled each of those engines not too long ago. It will have to turn a lot more rpms to pull the same hill, but it will do it. It will also have to downshift a heck of a lot more than the other engines too. I do the same thing all the time with my 5.4 and 7.3. My 5.4 has much less tq but much more hp and it will run circles around my 7.3. Any hill my 7.3 will pull at 2,000 rpms(161 hp and 425 tq) my 5.4 will pull just as good at 2,500(166 hp and 350 tq) even though the tq is wildly different.

 

Someone needs to come up with a CVT transmission that can bolt behind a PSD, V10 and a Semi engine (just for fun of course), that will hold each engine at their peak HP level. That would once and for all end all debate.

Even though the math has already proven more then once that the higher HP motor with the proper gearing will always put more torque to the wheels then a lower HP one.

 

The math might have suggested it, but no test has proven it....

 

The pickuptrucks.com test proved it. When the PSD topped out on RPM/speed, the V10 was continuing to climb in speed.

 

That didn't prove anything, it still had 5 seconds to make up. Yes, it took 5 seconds longer to go 700 feet than the v10 did. And, since the hill was done, we have no idea if the v10 had more in it or not. And....it was a srw 3/4 v10 vs. a dually 1 ton psd. Put them in the same body and see what happens.

And yes, this had been discussed over and over. It "proved" nothing. And look at the dieselpowermag article that showed the v10 with less hp to the rear wheel than the psd, significantly less. That has been argued too.

 

It appears this subject has been covered in all dimensions. But, I have to add my $5 worth (inflation). I bought my 1999 PSD new because diesel was cheap, the International 7.3 was known for longevity and this was the last new truck I will buy. I am not sorry I bought it as it lives up to my expectations.

That being said. I would never buy another light duty diesel truck. The fuel is too expensive, the engine premium bought new is too high and all engine parts seem to cost way more than a gas engine. Compare prices for replacement starters, for example.

While the diesels my get better MPG, I wonder if the fuel costs balance out with a V-10 burning 87 octane gasoline.

My choice today would be the V-10.

 

Well, I think the argument on a 3V V10 is better against the 6.0 (reliability issues) and the 6.4 (not much better fuel mileage than the v10), but for 2011, there is no v10 and the psd puts out 400/800 now at 18 to 20 mpg. Tough to argue that against the 6.2, unless you are not going to put many miles on it, thus negating the ongoing fuel mileage difference.
