Ed, I'm not sure anyone is saying they expect it to be bad. I don't expect that, and in fact I think it will be a great improvement over the anemic 5.4L.

My issue is only with the loss of choices in the Superduty. Okay, I will admit that I don't think the 6.2 will be an equal of the 6.8. Engineer Mike pretty much acknowledged that.

So we have two choices where we used to have three. We can choose the 6.2 which may have somewhere around 400 lb/ft, or pay a huge premium for the 6.7 D which is reported to have over 700 lb/ft. As Engineer Mike said yesterday, those who haul heavy and often will not want the 6.2. That is a lot of people who will be forced into diesel, or another brand. There is a 300 lb/ft gap in the lineup that calls for another engine choice.

 

I think its a good thing the new 6spd can shift manually. I suspect when towing at and around highway speeds with the 6.2l the trans will hunt between 4th, 5th and 6th a lot. The 6.2l should like 4.30 gears much better than 3.73s. Ford just will not get rid of those 3.73s. Shouldn't be too long until actual rear wheel dyno numbers are posted on here. Mike at 5 Star has a 6.2l on order with the 4.30s.

 

Heck, I think I can guesstimate and produce HP and Torque plots for Mike's new 6.2L with pretty good accuracy based on the clues I have so far.

To recap
1. Peak HP at 5500 rpm (my guess around 425hp - what is yours? 1.1 hp/cubic inch)
2. Peak Torque at 4250 rpm (my guess around 385 ft-lbs - what is yours? 1 ft-lb per cubic inch)
3. HP = Torque at 5252 rpm
4. 80% of max torque at 1250rpm
5. 90% of max torque at 2500rpm

So, what magic numbers should I use for peak torque and hp to generate curves???

 

I agree 100% with your statement. Why Ford still uses 3.73 ???. A gas truck with 6 gears can only use a 4.10 std or higher in my opinion. I see the 6.2L as a best of both worlds engine. For the average truck guy like me that tows/huals 20-30 times a year with weights of 5000-10000 lbs; I think it should fit nice. Now will the 6.2L be a replacement for the 6.8L.. I dont think so... I am going to miss the ole V10s... It was the main reason i sold my diesel years back..

As for dyno'ing, your right shouldn't be long before that happens. It will be interesting to see how Ford does with their engine and transmission calibrations. From what i have seen on the newer 09-10 F150's should be solid or much improved over years past.

 

The dyno'ings been done, I'd bet. I am certain that ford wants all the truck magazines to release the hp/torque numbers at the same time at the end of Feb along with Ford....

No guesses on numbers yawl?

 

I am more interested in rear wheel dyno numbers and the hp and torque curve graph than flywheel numbers. The 5.4l and 6.8l in the SD has over 30% drivetrain loss. I'm interested in seeing if that will be less with the new 6 speed or about the same as the 4R100 and 5R110. Mike has already posted good data on the 2V and 3V 6.8l so we will see how the new 6.2l compares and how much he can improve on the stock numbers with tuning. Also interested in seeing what Fords somewhat new VVT can do.

 

Not much point in guessing, I suppose. He said it would be over 60 HP per liter IIRC. So your 385 estimate sounds fair to me.

i asked the question about heavy towing every day mike said if 10klb trailer every day is your game diesel is probably what you want now in all honesty people do it with the v10 but most people will always say go diesel if your towing that much daily.

between the power the new 6.2 should make along with the rpms it achieves and the new trans its coupled with i really doubt any of us will be disappointed trailering with it

again he said it best when he said they are making the best gasser they can so that all potential ford buyers that want a gaser will come back to ford. theres a reason we love ford trucks lets see if they can make us proud again before we condemn their newest gem

 

For crank numbers i am hoping for at least the 400 plus mark on hp/tq... from Ford......

 

Interesting debate.

When the internal combustion engine came out, it was said it would never out-pull a horse team. It did.

When Detroit started producing automatic transmissions, it was said they could never replace a manual. It did.

When Detroit started producing overhead valve engines, it was said they would never replace the L-head (or flathead) engine. It did.

My point? It's an evolutionary process. The 6.2L is replacing the 5.4L and the 6.8L engines. Regardless of who thinks this engine will pull harder than that engine or who has a better torque curve, the 6.2L is the new engine.

If you don't like it, don't buy it. I am still a huge Ford fan and still think the Super Duty platform is the best towing pickup made.

 

Or in more modern terms, when ford started putting the modulars in everything, people were still diehard pushrodders.

(And do you mean Allison for the automatics)

 

Another thought on the 6.2L compared 6.8L/5.4L. I think we will see many more aftermarket performance products for the 6.2L. With it being a V8 that will be possibly in other Ford models in the future.
Raptor we know, F150 most likely, Expe?, GT500?

 

It will for shure make it easier for the aftermarket having only one gas engine in the SD. No more having to make seperate parts for the 5.4l and 6.8l in the SD. I figure the 6.2l will get a stroke increase in the future and the aftermarket parts should work on the stroked version as well because not much physically would change. More CI should help get more torque down lower. If Dodge does put the 6.4l in their trucks with 450hp and 500tq, Ford will be made to up the power of its gasser to meet or beat dodge.

 

I was thinking more along the lines of the Buick Dynaflow.

 

Brand new here! This post is not meant to irritate or offend, just to offer a different perspective and maybe even a little humor.

Back in 1988, I hauled 13,500 pounds (total combined payload, van, and trailer weight) from North East Texas to Calif with a 3/4 ton 1970 Ford van with a 302 engine (The biggest available engine in that generation van BTW, and no, the 300 I6 wasn't available in that generation either, just the 240 I6) with a three on the tree trans. Remarkably, the van and I lived to tell about it! I still have that van to this day as a matter of fact!

Years earlier my Grandparents moved a 65 foot mobile home trailer and a 500 gallon propane tank from Colorado to North East Texas with a 39 Ford stake bed truck that had had it's original 239 cubic inch Flathead V8 swapped out in favor of a (look out!) 1953 Mercury 255.4 cubic inch Flathead V8 and, again, the truck and Grandparents lived to tell about it! Amazing!

The point here is that I think towing life could be a whole lot worse and in fact has been a whole lot worse than what we have to work with in this new 6.2 and six speed auto. I just had to post this as I was genuinely amused at all the negative posts about the loss of the 6.8 V10. We will all live, I promise!
