Hi guys Just a quick question on what the new diesel engine is supposed to be. I have heard that the Navistar enigne is going to
be replaced. I sure its been discussed but I cannot find the message.

I am new to the PSD and the web site. Thanks for all the great info

 

[updated:LAST EDITED ON 21-Jan-02 AT 02:17 PM (EST)]Find some semi-insider info at [link:blueovalnews.com|Blue Oval News]. Info is at the bottom of the page.

 

Thanks for the info. Maybe I will be in the market for a
new PSD

 

It will be a 6.0L, 4 valves per cylinder push rod engine with a variable pitch turbo which will allow faster spool ups and the elimination of the waste gate. It has second generation injectors which as I understand it have the capability of varying the fuel flow rate internally instead of relying on pulse width to control the amount of fuel injected during each cycle (don't ask me to clearify that -- that's about all I understand about it). I've heard it run but there's something wrong with our dyno and it won't go to full load so I haven't seen the torque and power curves yet. It seems somewhat quieter than the 7.3L engine. It should be available for the 2003 model year. I am assuming that it won't be officially available until January 1, 2003 (that is an assumption on my part -- it will depend on what kind of production start up problems we encounter). If you have any specific questions, I'll answer them if I can. The E series vans will continue with the current 7.3L Power Stroke engine for at least another year.

 

Hey Joe, any updates on the 4.5L V6?

 

hey joe i am worried about droping from a 7.3 down to a 6.0. it looks good on paper for having more power but the duramax looked good on paper also and we all know that in the real world what happened there. guess i am worried about putting a big gooseneck trailor behing a 6.0 engine.

parts man

 

I don't see a problem with decreased displacement. The new engine will be far more technically advanced than its predecessor and will make power much smarter than before. You don't need alot of cubes to increase efficiency.

 

There is no replacement for displacement
also, 4 valves per cylender etc. (tech. improvements) allow for more problems and don't really interest me or anyone elce i've talked to. the current engine is great, and i hate to see it go

 

The last rumor I heard was that the V6 was on hold until further notice. I haven't heard anything official from Ford or Navistar -- just rumors.
I agree with the comments about no substitute for cubic inches. I too hate to see the 7.3L go. I haven't seen any horse power and torque curves yet so I'm reserving judgement on the 6.0L engine but it seems to me that this new engine is going to get its horse power by running faster. I hope they realize that torque is what gets the work done.

 

If Ford had any sense they'd kick that new powerplant out to the Socker Mom's in their new Excursions for a couple a years to see what kind of light-duty bugs appear.Burn em in for a while before introducing an unknown powerplant to commercial and heavy use. Just an opinion. Seems like International was still finding kinks in the PSD as late as October 01. I'd be happy if psd's stayed like they are for a few more years. Makes it easier on parts 15 or 20 years down the road. Don't need planned obsolece on a rig I plan to work for the next 20 years or so. By the way,I need info on auxillary undercarriage fuel tanks compatable with Lariet mileage computer. Do I need anything special? Sending unit and so fourth. Another Ford oversite. Can't get factory auxillary tank on truck with bed. Blue Oval needs to listen more to us users and buyers more and not some corporate bean counters. Don't start cutting so many corners that you have to rely on past glory like Ford did in the early 80s. build en tough. Build e'm strong and we'll keep buying and loving e'm. Stretch new

 

Note on planned obsolence: There is no reason that I know of for the parts availability to dry up any time in the near future because our facility in Brazil will continue to make the 7.3L Power Stroke for world wide use.

 

Why couldnt they put the variable pitch turbo an second generation injectors in the 7.3. To me that sounds like a better combo. I have heard people saying that the 5.9 cummins will be in the new Ford 250s and 350s, any truth to that.

I don't know. I wondered the same thing. One of the problems we've been facing is Ford wants a lighter weight engine so, apparently the engineers decided to do the same thing that has been done in the automotive industry -- make smaller engines with higher volumetric effeciency (that is precisely what GM has done with their Duramax).
I'd be surprised to see any Cummins engines in F250's & 350's. The Power Stroke engine fits right in with Ford's engine management strategy. Also, I don't know what Cummins' production capacity is but it may not be too much more than they are now producing. If that is the case, they wouldn't have the capability of sending Ford any significant number of engines for their use because most of their production run would be already dedicated to Dodge. The new production facility being readied to manufacture the 6.0L Power Stroke is supposed to be capable of 350,000 units per year, all of it dedicated to the Ford F-series truck.

The new block makes BETTER torque at the SAME RPM as the current 7.3.

However, here is info I posted on another forum a while back. The table is from blueovalnews.com:

Engine Specifications


7.3L diesel
6.0L diesel

MAX sae net horsepower
235@2700rpm
305@3600rpm

MAX sae net torque
500@1600rpm
550@2000rpm

MAX sae net torque
485-490 @1500 rpm
480-520 @ 1500 rpm



While I would be concerned if the ONLY HP/Torque numbers were listed for the the higher RPM's, take a look at the second torque spec. At 1500 RPM, the 6.0 is ALREADY making at least the same numbers as the 7.3. By the time we hit 2000 RPM, the 6.0 is ahead of the 7.3 by 50ft/lbs.

We know that HP is simply a function of torque and RPM. So if we do the math for the higher RPM numbers, we see:

For the 7.3 we have:
(235HP x 5252) / 2700rpm = 457 ft/lbs of torque at 2700RPM
seeing as how this is the peak, we know that the torque drops off after this point.

For the 6.0 we have:
(305HP x 5252) / 3600RPM = 445 ft/lbs of torque at 3600 RPM
while this is slightly lower than the 7.3, it is also 900 RPM later. Unless there is a drastic dip in the power curve, I'd bet the 6.0 is ~20-30 ft/lbs ahead of the 7.3 at 2700 RPM.


So it seems to me, that what we have is the new engine making up to 35 more ft/lbs of torque at the low end (1500RPM), meeting or exceeding the 7.3's peak torque at 1600, and maintaining a relatively level powerband almost 1000 RPM longer than the 7.3. Maintaining power well past the 7.3's red-line, I might add.

Couple this higher and longer power band with lighter engine weight, and I would expect a truck that has greater power, as well as lower overall weight, therefore a greater load/tow capacity. Using less fuel and generating less emissions to boot. And, given an extra 900 RPM to play with in the power band, transmission design, and programming should more efficient from both a power and mileage perspective as well.

I've seen the same numbers you have, Steve (I may have read it on your previous post). What I want to see is the engine running on a Dyno that has been calibrated by someone I trust. I am not impressed with advertised torque and horse power figures put out by the people trying to sell me a vehicle.
Just because I'm paranoid, it doesn't mean they're not out to get me!
