gentlemen,

i've been in the market for a superduty lately, but may wait due to an article i just read, quite interesting. It seems Ford is going to a 6cyl. diesel next year which will create 325HP and 550 ft./lbs. of torque. This is compared to the current 250/525 i believe. I know, I know, 250 hp is enough, but wouldn't an extra 75 be nice?? The fuel mileage will also increase by 10%. Thought it was interesting, but still don't know if i'll be able to wait!!

It ain't six cylinders, it is a V-8, unless they just recently changed the whole Configuration, it is also a 6.0 liter 366 C.I. It is supposed to be a killer motor, but aren't they all when they first come out? The thing that ismost interesting to me is the 5 speed Automatic that is coming with it. Now that should be a world beater. If you want more ford diesel information fo to www.ford-diesel.com

Hey Jon Fife, NOW YOU TELL ME.

Always AFTER THE FACT.

Ok I am selling my 8 week old Ford Power Stroke, any takers?

Ordering that new beast once I wake up sometime today, right now the darkness is going away as the sun pushes up and my eye lids go down.

Jon if I were you I would order the new one then you can tell Scott how the tranny holds up!

Just a couple of quick points:

Torque gets you out of the hole and started rolling.

Torque keeps you from having to downshift on hills, keeping bot momentum up and fuel consumption down.

Lugging a diesel engine is not bad for it.

Horsepower only equates on a flat, level road to more speed.

Therefore all things being equal a high torque rise will give better overall performance than high horsepower. Case in point any gasoline engine of similar size will have higher horsepower than a diesel. It will aslo require much more shifting and fuel to operate in the same environment.

I know from personal experience when I used to sell Mack Trucks years ago. I was selling a 300 HP Econodyne against 400 HP Cat/Cummins/Detroit engines and doing the same job with better fuel economy. Horsepower is impressive but torque does the work.

Just like in pressure washing, for most applications flow is better than pressure. In engines, torque is better than horsepower.

Just my $0.02 worth. Cheers.
 
Excuse me Michael, but I have to disagree. Lugging a diesel is very bad for it. It does not allow the fuel to burn completely, and it increases stress on the internal components of the engine that can significantly shorten engine life.
I dorve a truck for too many years, and actually had a boss that would pull the dipstick at layoff and smel it to see if he could smell diesel. If he could he would let that guy be the one that got layed off.

The motor is smaller, in displacement. The current powerstroke is a 7.3 liter, or 444 C.I. motor. Part of the reason that the new motor develops more horsepower is because it is a higher revving motor than the current one.
As for Jon, he hasn't been the same since they took him off his medication.

Diesel engines are compression ignition and all lugging does is lower the rpm of the engine but does not burn any less efficiently.

In a compression ignition engine the fuel is ignited by squeezing the fuel/ air mixture to the point it explodes. The fact that diesel engines are designed for these explosions means they are built to withstand the shocks. Diesel engines, with the exception of 2 stroke DDA's, are usually low RPM, Mack Trucks typically redline at 2100 RPM my Jetta TDI redlines at 4100 RPM. An old Mack E9-500 had 500 HP at 2100 RPM and 1609 ft-lbs at 1050 RPM with an idle of 600 RPM. The 1.9 litre TDI engine in my VW generates 90 HP at 3600 RPM and 153 ft-lbs at 1950 with an idle at 900 RPM. Oh, I also get 51 MPG for an average fuel consumption.

As a matter of fact at idle a diesel engine is ~70% more efficient than a gasoline engine. Actually from a purely stoichiometric view a gasoline engine burns fuel most efficiently at a lugging RPM.

However, the low torque characteristics mean that at lugging, a gasoline engine will typically stall. My Jetta TDI will idle along at ~25 mph on idle all day long if I let it.

Gasoline engines have short stroke pistons which mean torque shows at a higher RPM than a diesel engine with it's typically long stroke. Also, diesel engines will have a greater percentage of ultimate torque and will have more of it through the RPM range than a gasoline engine.

All smelling an oil dipstick for a diesel smell is a wives tale designed to keep driver's in line, IMHO :)
 
I looked at my notes on the engine in my Red truck. It is a 1998 427. They say it is rated at 225 Hp with 385 pounds torque. Yeah I know its not a Ford but torque is torque!

This truck has a very high profile (almost 13 feet) and that cuts a lot of wind and when we are fully loaded it weighs about 34,000 pounds. We don't make jack rabbit starts but we can maintain interstate speeds (60-65 mph) without any problem even with a head wind.

A Jetta TDI??? I knew I liked you, they are a really cool car. As for the lugging thing, I will still agree to disagree, but I am looking at it from a dumb truck drivers point of view. :rolleyes: I do remember that when they first came out with the 60 series detroit that they taught us the progressive shifting technique, where we starte shifting at 1200 rpm's. It was pretty effective in saving fuel. I got so used to it that I did it on an old Cat 3406 B with 425 HP and averaged around 8 MPG over a year. The best before that was 6 MPG. A couple of thousand gallons of fuel over a year really adds up.

Oh well, enough of a rant. Dave, I know you are used to those gas engines, but you really, really need to try a diesel in you next truck. You will be amazed at the pulling differences with it, over that 427.

Hi Scott,

Yes I know about diesels and pulling power. I ran a few truck fleets years ago. Spec'd out a few also.

I guess the first thing I would be amazed with would be the Price!:eek: Last time I checked it would add $5000 or so to the price of a new chassis. Another reason for staying with gasoline is miles. That Red truck is almost 5 years old and only has 66,000 miles on it! Dealers tell me that you really should put on at least 30,000 miles per year to justify the cost of the diesel engine.

Dave Olson
 
Only 66,000???? I have that on my personal truck in a year and a half. I have two other trucks that average about 35,000 miles a year. I guess withthose low miles it would not make sensse, unless you are of the mind to make it up on the resale.

Scott
 
I have never seen yours, but have seen one like it in my rear view mirror, while I was pulling it out of a snow bank.

Just haven fun here. I was a ford man up until a few years ago, and now I drive a chevy 3/4 ton, and my cook drives a Tahoo. The older I get the more I like the ride of a chev.

Don't want to start a pissen match here, just haven some fun.

That is a nice looken truck.
