just wanted to let you all know that ford is giving out more power for everybody that has a 2011 here is the link Ford upgrades diesels for Super Duty pickups.

 

Yep, see the sticky at the top of this sub forum for the discussion: Super Duty reclaims the top

 

Ford planned this before the new Super Duty model year was released. They were simply waiting in the shadows for the first '11 Duramax communication to hit the air waves. It will not surprise me if the folks at GM anty up again.

It's on folks and I love it, who needs an aftermarket controller for power upgrades when you have the manufacture doing it for you!

 

Very strong rumor out there that the new DuraMax is tapped out at 397 due to engine block issues

 

Not speaking of their current block. Compacted graphite technology is available for anyone who wants it.

 

Ford obviously had more power planned for the future, but I don't believe they had planned on upgrading the frame to keep up with GM!

 

I'm not sure this is true... I read that the internal stresses on the '11 is no more than the '10 year model and Banks engineering is pushing some serious power with these Duramaxes. I wouldn't discount the horsepower/torque war is over just yet!

 

We need to look at stock vs stock. Tunes will tip the tabel for sure. Even if it taxes what the engine is capable of.

How can more power in the same package not raise internal stresses? Not arguing, just asking.

 

I've got the same question.

This motor has so much HP in comparison to the 7.3L motor and its a half litre smaller.

Heck, even the 6.0 had what, about 50 HP more than a 7.3.

Unfortunately, only time will truly tell. I have a lot of faith in technology and manufacturing practices, but we all have to wait and see i guess.

 

IIRC, the 6.0 had 100 hp more than the 7.3. It also had a lot more headaches

 

I think there will be increased stresses, but I also think the power and torque was so underrated and conservative for the sake of durability and "room to play" on the competition and updates, that this power update will not hurt it at all. Just think of where diesels are right now. Ford makes the 3.0L V6 diesel for Jag/LR with 270HP/440 lb-ft. If you put that in terms of 6.7L (same power and torque per liter), that would be 600/980! So, with the tough big CGI block, 400/800 is probably still pretty conservative.

 

I am not questioning the strength or stress capacity of the new 6.7 Ford. Ford has been nibbling around the edge of this power increase for a while. They have hinted that more is coming. The question for Troy was about the DuraMax

Watch the link... The project manager specifies cylinder pressures stay the same as '10

BTW... Also remember the Duramax now has a ninth injector that will eliminate the extreme cynlinder temperatures during regens and all the stresses that this induces on the engine and components so there is less fatigue during regens. Actually regens are transparent to the Duramax engine components which is a good thing. Wish Ford would've taken the same route!

Thanks for the link. It makes sense when you connect the performance gains made possible by the def system. Ford has used the same thought processes with their new engine. It drops very little in power during regen as well. I see a 2 to 3 tenths drop in average fuel economy for less than 10 minutes. At 8 or 9 minutes the mileage begins to recover to it's normal numbers. That being said, the block may still be at it's maximum for the GM engineers. It may have been there all along and that is why they worked so hard to keep cylinder pressures the same. Ford on the other hand has been a little flirtatious about even more power that may be available. They do not appear to be at all nervous about being near the edge.
