compared to competitors that use forced induction in their motors Ford is about one or two generations behind in terms of output per liter from a similar configuration. Most single turbo motors today are at least at 120-130 hp per liter. Ford uses a second turbo and is getting lesser results. Maybe its a bad overall engine design but I am not impressed by the output.

I am not going to argue that the motor needs to last under load but then why not remove a turbo, beef up the internals with the cost savings and have a more reliable motor with equal power output for no cost increase?

Not trying to be a hater, just dissapointed at something that could have been so much more from an efficiency standpoint, power standpoint or cost standpoint.

Heck the new Hyundai Turbo for a regular old family car gets the same power density as a new Porsche 911 Turbo at 137 hp per liter.

The articles I've read is that they are using Diesel type technology. Maybe that would include beefing up the internals to handle the torque? Also this motor may not make the hp that you are speaking of, but doesn't it make much more torque than those you refer too? Isn't torque the real measure of a truck engine?

They are expecting 23 mpg highway rating on a half ton pick up with more power and about the same torque as a 5.4L v8. That impresses me.

If memory serves me HP and torque were about the same on the 3.5 ecoboost. something around 350 lbs of it. At least it is a flat curve starting around 1500-1800 RPM like you mentioned in a previous post. that is more than the 4.6 but not the 5.4

I'm sure it will work just fine for a lot of people

From the Ford web site (specs for the Taurus SHO version):

The 3.5L EcoBoost™ is the first North American production twin-turbocharged direct-injection V6 engine. And Taurus SHO is the first and only vehicle in its class to feature the EcoBoost engine.* This engine provides better fuel economy** and fewer emissions as compared with a V8 engine. EcoBoost combines two different technologies – turbocharging and direct-injection – to deliver the performance of a much larger engine with the fuel economy of a smaller engine. It churns out 365 horsepower and 350 lb.-ft. of torque across a wide 1,500 – 5,000 rpm range.† And it does all that with an estimated 17 city/25 highway fuel economy.

It's not a Scorpion diesel, but I'm pretty sure that this engine will do just fine in a light truck...

I know they were supposed to incorporate diesel technology to help out with the longevity of a turbo'd engine, but I am still worried about how the engine will last compared to its normally aspirated brethren.

The "diesel technology" is direct injection, and squirting oil up into the bottoms of the pistons. DI is a newer technology for gas engines but it's a solid technology, and that oil cooling trick has been around forever.
The industry has been messing w/ turbo's for a long time, it'll be fine.
Then again, just get a Scorpion and you'll have absolutely nothing to worry about...

lol!

for merely $50k at that. Maybe you could combine two Mahindras to get a 4.4 liter inline 8 for that price

oh come now... a nicely equipped standard cab long bed (TR20 style) w/ the Scorpion is less than $45k... And here's the beauty of it:
1) It actually exists, you can buy it today
2) It can be serviced at thousands of Ford dealers across the country
3) It's guarrenteed to have resale value
4) It can tow your two M&M's and prolly two more...

2 M&M's ,what is that about 5 grams? I sure hope it could tow that.

At any rate I know you can get an F250 like that but come on. Have you seen anyone who doesn't have an F250 with every option, lifted 8 inches, with 5 inch pipes spewing black smog?! It is basically the daily commuter ride around here. You wouldn't be a proper soccer mom or secretary without one.

LOLon the M&M's!

Well... my '99F350 is "only" an XLT. No black anything spewing from my ride. But yeah, what u describe is in abundance here also. Just show-boaters, but hey, it's their $...

Anyway, didn't mean to hijack the thread. I spew on about Ford diesels in other parts of the forum.
