I want your opinions on the Ecoboost.....

[kurtkrum]

Just to circle back - I bought the ford f150 FX4 with the Ecoboost engine. I take delivery tomorrow. I'll periodically update you guys on my experience and on any issues I experience.

Hard decision...all the trucks I looked at were awesome.

True. But it's clear that a lot of people that may read this will think, "Yeah! I need 3.73 gears too! They took our jobs!"

That's the way these forums work.

The truth is, you probably don't need 3.73s with today's modern 6 and 8 speed transmissions, particularly with modern power/torque levels at relatively low rpms.
Most people don't understand the engineering, or at least dig deep enough to find those answers.

Lots of folks, especially those reading this forum, will choose to put larger than stock tires on at some point. Getting the highest numeric gears available makes sense in that case.

And that would be a great reason. I asked WHY in hopes of legitimate rationale like "larger tires", not "my brother's cousin's friend has a Tundra with 4.30s and it can tow a space shuttle...and so I need 4.30s too"

Congrats on the truck!!! Keep us posted but I think you'll have a good experience.

Cheers,

If by 'tow kit' and 'decent axle gears' you mean waiting for the Max Tow Pkg with 3.73 gears then let's do some math

Transmission Ratios x Gear Ratios = Total Gearing

Toyota 6 speed automatic
1st 3.333 x 4.30 = 14.33
2nd 1.960 x 4.30 = 8.43
3rd 1.353 x 4.30 = 5.82
4th 1.000 x 4.30 = 4.30
5th 0.728 x 4.30 = 3.13
6th 0.588 x 4.30 = 2.53

Ford 6 speed automatic
1st 4.17 x 3.73 = 15.55
2nd 2.34 x 3.73 = 8.73
3rd 1.52 x 3.73 = 5.67
4th 1.14 x 3.73 = 4.25
5th 0.86 x 3.73 = 3.21
6th 0.69 x 3.73 = 2.57

GM 6L80E 6 speed automatic
1st 4.02 x 3.42 = 13.75
2nd 2.36 x 3.42 = 8.07
3rd 1.43 x 3.42 = 4.89
4th 1.15 x 3.42 = 3.93
5th 0.85 x 3.42 = 2.91
6th 0.67 x 3.42 = 2.29

Notice that the Toyota transmission has a tight spread, really needs a high numeric ratio to leverage it
The Ford and GM are pretty close to each other, both having significantly deeper 1st and 2nd gears than the Toyota
So off road, a 3.73 Ford or GM has more leverage than the 4.30 Toyota

It's a SYSTEM, and can't be decided on rear-end gear ratio alone

Given the much higher torque levels of GM's new DI 5.3L , the 3.42 geared GM has more torque in every gear, at every normal rpm over the 3.73 geared 5.0L Ford

Comparing the GM 5.3L with 3.42 gearing to the Toyota 5.7L with 4.30 gearing, the two trucks are within 3-tenths of a second 0-60mph empty, 3-tenths with 1,200 pounds in the bed, and 8-tenths with a 8,500 trailer attached.

Yet every day, empty, the GM would return 4-5 mpg better fuel economy, equal low-rpm off-road power, similar tow ratings, and similar street performance to the 4.30 Toyota. And simply kick the Ford 5.0's tail, being much closer to the EcoBoost with 3.73 gears, which returning better fuel economy than either.

Still want to wait for the 3.73 Max Tow Pkg?

The 5.3L in our Avalanche ain't doing so hot. Seems like a dog, poor mileage and power. Can we still get the 6.0L or better in the GM 1500 sized trucks?

Still. Don't fear the gear. Get as much gear as you can in the model truck offered. You won't regret it. Loaded performance is greatly improved. 3.73? Bah, that's a soccer mom ratio. 4.30 baaaaby! I won't drive any gasser with less than 4.10.

Can we still get the 6.0L or better in the GM 1500 sized trucks?

The 430ish horsepower 6.2Ls will be available this Fall. And only with a 3.73 gear.

I won't drive any gasser with less than 4.10.

Remember, the transmission has a lot to do with it too. With more gears in the transmission (9 speeds are coming!) and their wider ratio spread, there is less need for a shorter R&P.

This might be a rare case, but holy cow, this poor guy!

Not sure if this picture is real or chopped but it has been cycling around Facebook for a few days. Real or not, it is funny :coffeedrink:

Man- i waded thru 60 pages on the above link to get to a closed thread. That will teach me not to skip right to the end

I had been following that thread closely. It's too bad they closed it.

I would like to see how he made out 3 blown engines seems insane!

I purchased a F150 EB new in 2011. The truck now has 82k on it; has pulled a 6K+ trailer from PA to western Colorado and back; has completed a loaded hunting trip to Montana; and is driven all over the eastern seaboard for work. It is the most versatile truck I have ever owned in that it is relatively economical (compared to it's varied abilities), tows like a former Cummins I owned (in the 6k-8k area) and rides like a former GMC I owned. It is rapidly becoming my favorite truck of all time, however, it has not been without issues. Some of the concerns I read about in this thread are real---some are not (at least with mine). The transmission and electric power steering have performed flawlessly on my truck. My engine has suffered from the common hesitation at 55-60 mph as well as the problem of going into limp mode during WOT. Both issues were rectified as "FordGuy1" indicated---the former was a throttle body while the latter was a coil pack. I was fortunate to have a reputable dealer diagnose the issues and the truck has performed perfectly since the repairs. Lastly, as with both the Dodge and the GMC, I have found Ford's front brakes less than desirable and replaced them with aftermarket brands. I usually keep my trucks until they have 250k+ on them, so the final verdict is not quite in. Nonetheless, I presently wouldn't hesitate one moment purchasing another...

I test drove a bunch of Ecos. They seemed real nice. I was going to order one with the 8200GVW package, but i lucked across a Ram 2500 Hemi cheaper.(it has 12k on it)
