Sshh... you're lying, making stuff up and editting the video tapes.

 

Hey Art you might want ot look again, the one I currently drive has 1675 and some of the Cat's (before cat stopped building on road diesels ) had 2100lbs/ft tq. 1450 is actually a low powered unit.

BTW here is the current smallest Detriot offered for on road use (DD13) note the LOW end of the torque numbers is 1250

http://www.detroitdiesel.com/engines/dd13/

Their big engine produces 2050

oh and BTW hp is NOT a good way to compare anything when it comes to pulling. Now if your talking drag racing yes but pulling no. did you know that rotary mazda engines can be made to produce over 500hp. Dang I bet that sucker would pull your and my trucks up a hill backwards. Of coarse that's only producing 150lb/ft of tq which is what actually MOVES things but it does spin 18000 rpm. there is a bunch of guys that have Briggs and Stratton motors that will dyno at 70+hp bet if you hook 10 of them up ot equal the cylinders on a V10 they would pull a freight train. of coarse they only have 20lb/ft of tq.

But of coarse you CAN make comparisons where by coming up with gear ratio's that have no bearing on reality that the V10 hp will make all the difference. That does nothing for the discussion other then prove you can create a situation where the engine of your choice given the right conditions will be better. Like I said I have a 7.3 and you know if I gear it just right, put it into a 4x4 F750 chassis with floater tires and hook up against a F250 with street tires I could pull several trucks across a muddy field all at once.

but trying to make the comparison to electric engines is even worse apples to orangers then a gas to diesel comparison. you can NOT compare any internal combustion engine to a electric motor. There is a reason that trains are not actually powered by the diesel engine, they are electric. the diesel just runs a huge generator. Electric motors produce HUGE amounts of torque ALL the time. (they don't actually have a torque curve, they have a straight line, it's on or off but you adjust the HP rating by adjusting the rpms)

 

Oh, you're not talking about a Powerstroke

 

No, I thought I said I was talking about the Semi I drive, or in th ecase I mentioned it was one of the first ones I owned.

I have no illusions that my 7.3PSD is going to outpull the 3v V10s. I just like it cause it doesn't have the issues of the 6.0, it doesn't have a bunch of expensive emission controls (it didn't from the factory), it's paid for (which I think trumps ALL arguments here) and I can make my own fuel to run it.

 

If you gave that rotary engine gearing so it could turn that 18,000 RPM at 60MPH it WOULD pull your rig backwards!

500 x 5252 / 18,000 = 146 lb-ft of torque. Using that same theoretical semi mentioned earlier (3.73 rear end, 40" tires) it would require a 9.6:1 ratio in the transmission to do 60 at 18,000 RPM. 146 x 9.6 x 3.73 = 5228 lb-ft of torque to the wheels.

Also, traction motors in locomotives are usually constant power motors. They put out the same horsepower regardless of RPM, which means torque has to go down as speed increases.

 

and with the right gearing a lawn mower engine will out do all our engines.


This proves what again?

 

Thats why I drive an old 2V.

 

Times Two

 

Actually, it wouldn't, if you figure speed into it. You COULD gear a lawn mower engine down to where the torque would exceed the PSD or V10, but it would never EVER do it at 60MPH.

 

Okay kids, for the 40th time, here is what I am getting at. LOL

The 2V V10 is 310/425. The 6.0 is 325/560. In that last video that was just reposted, I think everyon can agree the 6.0 DESTROYED the v10, despite a small 15 hp advantage. The V10 was even programmed so I would imagine the V10 even had a hp advantage.

Okay, the 7.3 was obviously not running properly and was running hot with a 200k transmission. Even so, it is 250/505, so at least a 60 hp disadvantage.

Now tell me one thing, was the v10 closer to the 7.3 or closer to the 6.0? It was clearly a lot closer to the 7.3, so again, please try to tell me how hp is more important than torque? Or how the 12 hp advantage the 3V V10 has means it will outpull a 6.4?

Keep in mind, when engine makers design engines for trucks, they detune the hp for a gain in torque. One example of this, the Chevy 5.3 in 2006 was 295/335 while the Impala SS my wife has is 303/323. I can find other examples of when they use the same engine in trucks as the car, where almost always the truck has less horsepower and more torque than the car. Why do they do that? LOL

 

Well then your 2v is every bit as good as my 7.3 and we beat the 6.4 and 3v guys all to heck



Ok beyond that factor.

i have a simple question, not just for the v10 guys but anybody here.


Which rpm is the 3v V10 going to pull better? 3250rpm or 4750rpm?

how about those with a 6.4 psd? 2000rpm or 3000rpm

and the 6.0 drivers? 2000rpm or 3300rpm

And lets not forget the 7.3 guys. 1600rpm or 2600rpm.... I will answer that mine pulls a lot better and holds a lot better as well as gets a LOT better fuel economy between 1600-1900 then it does anything north of 2000rpm.



OOPS almost forgot the 2v guys sorry. But I think yours is the same rpm rangers of 3250 and 4750

 

That's the point, you can make up numbers and gear ratio's that have nothing to do with real life and it proves NOTHING. in an attempt to prove that the V10 will out pull a semi tractor trailer engine someone made up some gear ratio's that give a mathematical advantage to a higher rpm engine. But reality is much different.

 

Monster, just wait until Josh comes back to the discussion! LOL

 

Ah................ well for that you need one of these. Both the PSD and the V10 will sink

What's really bad is even in Aug that isn't really that far removed. We are having major flooding issues around the state lately. I think there is something like 500 homes flooded out.
