You got that right!

 

I am with you 150%!

We have a 12,000 pound trailer that we pull with a 1997, 4900 series International, 33,000lb GVWR, DT466 and air brakes. Overkill? Maybe. But I'll tell you what, when I want to stop, I stop! The truck looks great, is adequately comfortable and it only cost us $6500. The mileage is actually BETTER than the 98 Dodge we use to pull our smaller 8k trailer, the insurance is cheaper and the registration fee is the same.

I just can't understand the 'small truck-big load' mindset, but to each his own.

 

Hey chaikwa, I was starting to think that I was in a world of my own here. I know this post was about the new F series super duty but I questioned the large hp they are boasting about. I'm with you I don't understand the little truck big load stuff myself. I drive a large vehicle everyday and you can't sub anything for having the bigger stuff as you spoke of.
Sorry if I hijacked this posting but I was asking about the need for having this kind of power.

 

What was this thread about? I have forgotten and I'm not going to read it again.

 

Big Dodge's with little motors.

 

i thought it was about the new fords? lol
guess im a dumb kid hahaha

 

If this form was about Pickups It would be about pickup trucks have to much power the way it is. And Ford increasing it even more doesn't make any sense (to some) Doesn't make sense that pickup trucks keep getting bigger brakes, heavier frames (again to some people)
And what ever you do don't wish Dodge would match it

If this form was about financial advice it would be buy the right tool for the job no matter what the cost. Doesn't matter if you can use the tool you have and get by for a few more years. Run out and get a loan!!!!

 

For a 1 ton truck anything above 250 hp and 450tq is a waste

 

Then why put mods on your truck that is already to powerful??

 

Many of you are right,......this thread has gotten way off-topic.

Let's try to keep it on the 2011 Ford PSD and it's new engine. If you guys want to start another thread on how much H.P./TQ you REALLY need please start another thread on that.

Thanks.

That's actually incorrect. HP will not "get you to the TQ".

HP/TQ differential actually paints an incredibly detailed picture about the power band of an engine for those who are in the know. Torque is actual measurable power output, while horsepower is just a calculated made up number, so to speak. Horsepower is calculated by measuring torque, and multiplying that by RPM, and dividing that total by 5,252. To write it simply:

HP = (TQxRPM)/5252

The important aspect to look at is that TQ is multiplied with RPM, so the higher your HP is at the same torque output, then the higher your peak torque and power band is. The opposite is also true, where TQ peaks lower, then HP will be lower.

As an example, lets say we have a diesel that reaches peak TQ of 700lb/ft @ 1500RPM:
(700x1500)/5252= 199.9HP

Let's use that same 700lb/ft engine, but raise the peak TQ to 2300 RPM:
(700x2300)/5252= 306.5hp

For a tow rig, I'd rather have the lower HP number, and not have to wait for my torque.

This is also the reason that many Jap cars have to spin 8000RPM or more to put out any power. Since they produce no torque, they have to have a HUGE RPM number to multiply against that weeny little torque number into something that will even move the dang car!

Hopefully this post has been enlightening for some. For a gas car I want to see my HP/TQ numbers be pretty well matched, which means that the power band will most likely be pretty usable in the 3000-6000RPM range. For a gas truck I prefer to see HP about 80% of the torque, which means that it will have decent grunt below 2500 RPM, but not never need to be pushed past 5500RPM at most! A diesel hauler, on the other hand, I'd like to see HP be about half of TQ at the max! These are general guidelines, and not designed to be a replacement for a test drive.

 

Sorry John P, I had the page up in the background since before you posted that last message.

Anyway, to get on topic, I found a pic of the Scorpion Diesel. Still looks like a mess . Anybody know why on earth it appears to have a throttle body???

No problem lgp9999! We try hard here to keep these threads "on-topic" and stop the "hijack" of some threads when another issue comes up.
As I said, you guys are more than welcome to start another thread on the H.P./TQ issue if you want to.

Thanks.

My first guess is the throttle body is emissions related.

 

Man that is anything but a thing of beauty I sure do like the solid design and rugged looks of the I6 compared to that mess of garbage.
