Second Gen 3.5 EcoBoost and 10 Speed Transmission

Turbos make all the diesel owners proud. :) Without them the oil burners would be the wheezing pigs they used to be.

Personally, I'd like to see Ford add a couple of cylinders to the 3.5 and make a 4.6 ecoboost. With 15# of boost it would have the sea level performance (and gas consumption) of the old 460 at any elevation while maintaining the unloaded economy of a small block.

Take a truck like my 2013 Ram. It would be the cat's meow if I could have 3.42:1 for my everyday ventures and then when I hook to my rig push a button and have 4.11:1.

Not sure why you consider making improvements on an engine that has been vehicles for over decade is funny. I would think it would be more funny or odd for a manufacturer in this technology driven age to wait for the competition to pass them and react.

The 3.5 Ecoboost has been in the F150 towing heavy loads (for a 1/2 ton series truck) for decades? Huh, new one for me. I thought it was an all new engine and technology for the F150.

:) Hi, I believe that he said for over a decade, which could mean eleven years. "for decades? Huh, new one for me." This engine started in the Taurus before the F-150.

It's not the same engine that was in the Taurus. Same displacement and has turbos yes but not the same.

:) Hi, other than having less torque, and being in a front wheel drive vehicle, what makes this a different engine? As far as I'm concerned, a few minor differences doesn't make it a different engine.

You are correct. The 3.5 had a few beefed up internals to handle the extra abuse expected in a pickup, but largely is the same engine in the Taurus. The heads flow a bit more and turbos are different. But turbos do not an engine make... As I understand it the only reason the sho was limited to 365 ft lbs was to save the driveline downstream of the engine.

This is what I copied from Popular Mechanics webpage:

"While it might be convenient to think that this is simply the Taurus SHO engine turned 90 degrees and dropped into the truck's cavernous engine bay, that would be completely wrong. The aluminum block is all new because it bolts to a different transmission from the front-wheel-drive applications. The engine also has stronger main bearings. Like all 2011 F-150 powertrains, the 3.5 liter is matched to Ford's six-speed automatic. Additional major differences between the engines include unique heads that feature individual cam phasers for both intake and exhaust; the fixed-geometry turbochargers flow more and produce more boost (13 psi versus 10.5 psi); the main cooling system is upgraded.

These changes enable the F-150's version of the EcoBoost to deliver:

• 365 horsepower at 5000 rpm (on regular fuel)
• 420 lb.-ft. of torque at 2500 rpm (up to 90 percent of peak torque from 1700 rpm to 5000 rpm)
• 11,300 pounds maximum trailer-towing capacity "


From my own understanding the ecoboost in the F150 had to be built "stronger" for the increased duty-cycle or durability for the truck that would not be seen in the car.

I was thinking of waiting until the fall to buy my truck but it seems like too much new stuff to want to be the guinea pig for.

The Standard F150 is suppose to stay at 365 Hp but with 450# torque. The biggest fix is that they are now using a standard injector with direct injection to fix the carbon issues of DI engines. To bad it took this long.

The 3.5L Ecoboost hardly had any carbon buildup issues versus other direct injected engines because it doesn't have an EGR. In fact the carbon build up on the 3.5L was very minimal to where almost all owners can go the whole engines life without any issues or power loss. The 2.0L Ecoboost on the other hand had carbon buildup because it had an EGR system.

Although, I can see why you would say that. You have always disliked the Ecoboost even back when you were in the F150 forums and you had your blue truck.

I just commented on the 10 speed trans at F150forum with the post below.

"Do you really want to be the guinea pig on a new 10 speed transmission that was designed in part by GM??!!

My folks are Chevy loyalist and they've had more transmissions rebuilt and repaired than I would want on my worst enemy.

I had my fair share of issues with my 6R60 in my Sport Trac. Mainly just getting the correct program for shifting. Then my 2010 F150 6R80 that wanted to throw you through the window when it shifted before coming to a stop. Same trans just different torque converter and programming.

Other than a bad Torque converter that started whining right after I took delivery, the 2012 6R80 has been very good. I would rather have a strong and reliable transmission with great gearing and performance, than a new 10 speed bike, I mean transmission, that will undoubtedly be plagued by bugs.

It's nice to hear how Ford is going to combat the DI issue as that's a concern when paired up with a turbo. Wonder if the 5.0L is going to make it next year. It would be a shame to only have Turbo engines that are not trusted by everyone. It would make some people go to the competition.

I think the motor line up for 2016 is just right. Would like to see the 3.7L again but the 3.5L is a great engine and powerhouse in our '15 Explorer."

The port injectors are to reduce carbon build-up?

Carbon cleanup is an ancillary benefit. Primary reason is simply the volume delivery limitation with the injectors in the DI system (since timing has to be precise when fuel is delivered into the cylinder). As-is, tuners are already adding port injection to the current 3.5L simply to get more fuel delivered when the turn the boost way up.

Correct me if I'm wrong:
1) The port injectors are to reduce carbon build-up?
2) No mention of a CGI block like on the little EcoBoost?

Redesign isn't exclusively for the F150. In other vehicles it will be be pushing 600 HP. In the Raptor, its expected to do 450 HP!

Finally!! There might be something interesting from Ford :C
