So does anyone know why Ford has the 6.2 in the F250 so de-tuned from the factory? It is for fuel economy? It is to protect the drivetrain from abuse?? (ie, Torque-management like Nissan employs on the Titan, where it will not go WOT until 3rd gear?) To keep the power numbers lower than the Raptor/6.2L F150 from a marketing standpoint??

Whaddya think?

I'd love to tune mine and actually get WOT when I mash the pedal, but I dont want to get into a problem with warranty where Ford makes the dealership send it data-logs for warranty approval like they do with the diesels.

Anybody have any thoughts>?

The Raptor is a performance desert runner and not a tow/haul vehicle.
My F-250 pulls 11,000 pounds and I need torque to handle the load.
The Raptor is setup for racing.

I'm sure others will bring in more details but this is my unofficial non-mechanical knowledge answer.

 

Correct, the Raptor motor has a different cam in it, from what I read.

But, with the SD being a tow vehicle, why isn't 100% throttle angle available at any RPM? Is it to save the drivetrain from abuse/axle wrap, etc etc etc?

 

Just my uneducated take on this question,......I am surprised that the torque issue is even a consideration when the substantial drive train is the same as the diesel with all of its torque, if I am correct.
I think that Ford is holding back on Their 6.2 to see what Chevy/GMC comes out with in a 2500 pickup as all they have now is a gutless 6.0.sit back and see what HP they are producing then up it by 5HP with a tune just for bragging rights.

 

COULD BE!!!

 

I agree. The 6.2 engine just came out and Ford does not was to max it out so early. Chevy has some catching up to do and when they do thier gas V8 will produce a little more than the 6.2. Then Ford will answer back with a little more than Chevy and so on. If they maxed out the 6.2 from the get go then when Chevy or Dodge matches or beats Ford's power numbers then Ford would be looking at an expensive redesign of the 6.2 or a complete new engine. It cost Ford millions of dollars when they were designing the 4.6/5.4 engines.

 

There are a huge pile of reasons for this, some of them I'll touch on, as I see them anyways

1) Emissions. Snapping open (or closed) the throttle is a bad thing for emissions.

2) Future improvement.

3) Time-to-market. They need it out fast, and as long as it meets the target HP and trq numbers, and the emissions numbers, it's good-to-go.

4) Remember, a lot of these trucks are used commercially. If you give a driver a fast truck, they will use every last ounce of torque available. Which just makes the truck not last as long as it could.

Besides, it keeps Mike/5-star in business

 

I really don't know. In the F-350's over 10,000 GVW, it's only rated at 316/397, though I am told it is because the ratings are taken at a lower R.P.M. than 6.2L's in lighter Super Duties.

Why is the V-10 still around? Why isn't the 6.2L available in the 450 or 550? Where is the 7.0L Boss?

 

Really??? Can that be true with the 6.2L only having 316hp / 397 torque in the F350 over 10,000 GVW???

No way in the SWB F350??? Maybe dually and beyond right???

Emissions and fuel economy are two which sort of go hand in hand. Another major reason is people want a silky smooth truck and are known to complain about every little noise, bump, jerk and etc. They expect a 1 ton truck that is smooth like a Lincoln regardless of how bad it is for the trucks performance or longevity. The way my truck is setup would make these people run to the dealer and complain.

Heard the same.

Its still in the..

1) E-Series
2) F53 Chassis
3) F-450 and F-550
4) Will be and option in Fords medium duty trucks for the 2012 MY
5) Still available in generator applications (gasoline, CNG and LP)

Ford should have kept the V10 tweaked it a little for more power and put the 6R140 behind it. The V10 is a better truck motor IMO and Ford seems to think so also. The 6.2l is nice in the 150 and Raptor but is not needed, the 3.5l EB and 5.0l are fine for the 150 IMO. With the upcoming mpg/emissions regs and changes to Fords lineup I don't forsee the 6.2l being around for long especially in an F-150, kinda an engine to fill a void that was not there. The mpg difference between the V10 and the 6.2l has proven to be next to nothing and the difference probably has more to do with the transmission than anything.

The prototypes are probably stuck in a corner somewhere. My guess is we probably will not see it in a production vehicle made in any quantity.

 

The 5.4/6.8 also have the advantege of a very proven longevity/low maintnance costs. Any shop in the country sees them every day and can work on them. Parts are everywhere. If the 6.2 is around only 5years? Wont be the same situation


The two trucks in my signature pull my 7500lb trailer pretty similar. The 2011 is about 500lbs heavier and is an auto instead of a manual. The 5.4 gets 1-2 mpg better on same routes same driver and even on hills pulls very close to the 6.2. I kind of give the 10 a break becuase it was 20000$ less than the 11! I guess at the edge of gcwr the 6.2 would make a difference but at 15k gvw they are about the same

 

The ratings are taken at a different RPM, that's all. It's still the same 385hp available, but for emissions reasons, they take the measurements at a different RPM. It is 100% the same HP/Torque across the SuperDuty lineup.

 

I get asked about the lower rating all the time its just smoking mirrors. The 6.2L is just making power where they take the reading from 4179 RPM

I wonder why the 6.7L is not rated at the 4179 RPMs LOL

This is out of the Ford Brochure

 

Now I guess the big question is, what other components in the driveline train do the 6.2 & 6.7 share ??, Like transfer case, differentials, drive shaft and of course the 6 speed auto. transmission, etc. If most or all of the components are the same,….. than the 6.2 has a very strong foundation to build more power from. So once again,…Why is Ford so conservative with their 6.2 Tune?
Are the components the same ????????

 

I think one of the main reasons is for compatition. Who know's what kind of engines, GM or Dodge will introduce in their heavy duty trucks in the future. GM is suppose to working on an all new Vortec V8 lineup and Dodge may revamp the Hemi for more power down the road. After this has done Ford will be at the bottom of barrel in the power department with its 6.2L.

So in theory they keep the 6.2L in realtivly low tune now ''which is competitive with the compatitions engines'' then when the compatition upgrades their stuff Ford just up the tune on the 6.2L and it'll make competitive power numbers.
