For me, its between me and where I need to be.

 

But If you drop to second, then I will be in first.
The V10 does put more lb feet of torque to the ground than 6.0 can.

The 6.7 cummins is not in the F450/550......

 

The 3V V10 will trash any stock PSD before '03. It will run right with the newer ones too.

Are those numbers right?




That is not true.


Yes, but horse power is made by the combination of torque and RPM.

If they both ran the gears that fit them best, the higher HP engine would perform much more work than the lower HP engine. All the lower torque engine needs is gearing to multiply torque to the ground.

I dunno if that's gonna happen. If you do your going to hold it and your going to lose speed. But let's say you do. Try again on putting more tq down. 1st gear is 3.11x375=1166. 2nd gear is 2.54x517=1313 lbs tq. Your still not doing it.

 

HP Is a power measurement. It can be translated to KW power, etc.
With HP and gearing, you can create any torque you desire.
TQ is a measurement of the power being applied, but without RPM's is meaningless.

Lets play a game, you and I both have a go kart, and whatever gears we could ever imagine.
we both have 200 lb engines that make 100 HP. Mine makes it at 2000 RPM and yours makes it at 5000 RPM. Whos will be able to go faster?
It will be the same. HP is an absolute measure of power. You can use gears to get the most of the engine, but HP is HP.

HP IS the ability to do work.

when you say " 350 hp associated with 700 lb/ft of torque can do much more work than 350 hp associated with 350 lb/ft of torque." , you are mistaken.

It in fact CAN do the same work, just not at the same RPM.

 

I keep hearing this "my 7.3 stock can whip your V-10" and it is so far removed from reality it ain't funny. I'd like to see some stock HP/TQ numbers for the '94-'97 7.3, '99-'02/03 7.3, and the 6 leaker. Then show the HP/TQ figures for the 2005-2010 V-10's, just for the record. As far as a Cummins goes, the magnificant 5.9 as a stocker is a real pig and has to have alot of mods and expense to get a decent hp/tq rating.

Those TSB numbers for the 6 leaker came from a Ford diesel mechanic buddy in Utah.

What this thread is missing is a bunch of drag strip videos.

I searched, but can't seem to find any stock diesel vs v10 videos.

 

Here's some fuel for the fire. I can see it's not perfectly accurate, so take it for what it's worth.

Some V-10 info I found.

1999 V10...275hp around 400 ft lbs torque (2-valve)

2000-2004 V-10...310 hp @4250 rpm, 425 ft/lb torque @3250 rpm (2-valve)

2005 up V-10...362 hp @4750 rpm, 457 ft/lb torque @3250 rpm (3-valve)

Some PSD info I found.

Wow, William, good on ya for digging up that info. I have not run into a new 6.7 but have the 6.4's and solo, it was a dead heat at the "stoplight race". 6 leakers and 7.3's are easy unless they are super hopped up and modded. Same with Dodges and Chevy's, although the new Chevy is prolly a very hot number as well. Older 7.3's don't compare power wise.

 

As you can see, the PSD's are clearly "better". CASE CLOSED!

 

Thanks, Pap.

The 6.7's number can be higher than listed if they've had the 400 flash done by the dealer.

Now what is the weight difference between the V-10, and PSD trucks?

FWIW: To hop up a 6.0, all you need is a $400 tuner. A mild tune can show a 60HP gain at the wheels. That same $400 tuner can DL a 140HP tune, and make you think you were standing still. A super hopped up, and modded 6.0 is a bottomless money pit that goes really quick.

 

HP isn't the ability to do work. HP is a rating of the energy moving thru the system. Since you used the electical side of the equation. On a 120v 20 amp circuit 100w bulb is stronger than a 90w. But what about a 90w on a 30 amp and the 100w still on the 20amp. In electicy amps is like tq. Tq is actual force (power) it is not dependant on rpm. But once you start making rpm(momentum) you start getting HP.

 

Actually wattage is like a HP rating, and defines the amount of energy used regardless of voltage or current(W=VxA). A 100W lamp will draw .83 amps @ 120V. A 90W lamp will draw .75A @ 120V. It doesn't matter if it's a 20A or 30A circuit. If the voltage is lower the amperage will increase, and the opposite is true if the voltage is higher.

HP defines the amount of work a particular power plant is able to do over time. If you're an engineer looking for a minimum acceptable standard for a certain task which needs to be accomplished, you will define the job by the HP required to accomplish the task. Then you can move on to selecting the appropriate power plant to meet those needs.

 

Whats the difference between the 02 and 03 7.3 for 40HP and 5TQ? Just tuned down for the powdered rods?

 

The '03 was the same as the other years. I'm pretty sure thats wrong.

The V10 numbers are all for the pickup. The vans are diffrent and the Excursion still had the 2V in '05.
