Steel vs Aluminum F150

Thank you @Allhatnocattle...I actually had no intention of just spreading it all over the forum as you are saying. I just wanted to share the results with other F150 owners like myself. I know there are people on the fence over the aluminum vs steel debate and the V6TT vs V8 debate. Do you think I make money on youtube...lol. It's just a hobby, I have a full time job, I'm a military pilot and as cool as it would be to make a living on youtube that's not happening anytime soon. Just trying to share some videos I enjoyed making with other owners. Thanks for watching and commenting. Adam

I was mainly on the GT350 forums but I just sold my 350 last week so I decided to check the F150 forums out. I'm also on another F150 forum. Anyway, no hurt feelings here.

Whatever the OP's motives are for putting up the YouTube video, I'd like to thank him for doing it.
His results are in line with my "butt-meter" tests between my 2010 Lariat 5.4 and my 2016 Platinum on acceleration. The 2016, with a 3.31 rear, puts me back in the seat if I floor it, (and makes my wife nervous, LOL), the 2010 with a 3.55 never did. I log my gas mileage with every fill up, and got similar results.
So, while I was very satisfied with my 2010, as my posts on here show, there is not a thing on the 2016 that does not seem better.

Hate to say it but 3.31 gears will make a truck feel faster than one with 3.55 gears. If you think the 3.31 gears are quick, try one with 3.15 gears!
My ex 2014, may she rest in pieces, had 3.15 gears and made my 2016 with 3.55 gears a dog.

Are you really saying that a 3.15 will accelerate faster than a 3.31? Naw.
I only mentioned the 3.31 gears because it is supposed to be slower than 3.55 gears. But the 3.5 Turbo, and 500# less weight, blows the 5.4 away.

How exactly are you arriving at this conclusion? I checked my calendar and it's not opposite day.

Hopefully this makes sense;
Simple way to look at it, one vehicle has 3:1 gears, the other 4:1 gears, one revolution of a tire moves 40", so for every three turns of the 3:1 gears the tire moves 40", for the 4:1 gears at three turns, the tire moves 30".
So with the taller gears at a given RPM, the tires are rotating faster on the 3.31 than they are with the 3.55 gears.
Now for towing, the shorter gears rule since they get the engine up into its power band faster to apply the torque needed to move the heavy load.
For the record, the above is strictly for the Ecoboost, in that it produces torque way down low so that the 3.15 gears can really move the truck, but in a NA truck, the shorter gears will move the truck better than the taller geared truck, but the taller truck will overtake and pass it at some point. It all depends on where the engine can produce the torque. It is all about the torque with the gearing, which is why the 5.0 needs shorter gears than the EB when it comes down to towing and why the EB(up until the new models) have a higher towing capacity.
If both trucks engines spool up at the same exact rate, the 3.55 will launch faster off the line, but the 3.31 geared truck will pass it, so at 4000 RPM the 3.31 truck is moving faster than the 3.55 truck. This is why your newer truck feels faster than the old one.

2 ecoboost trucks, one with 3.15 gears and one with 3.55 (or 3.31, 3.73, 4.10, take your pick), the 3.15 will accelerate the slowest of the bunch all else being equal. It will be turning the least rpm at highway speed and get the best highway mileage, but the steeper gears have a mechanical advantage in getting the truck moving.

Off topic, but why did you sell your GT350? As a huge Mustang fan, and any other Mustang fan I know, that's our dream car. I don't know if I would ever sell it, if I'm ever able to own one haha.

So what we've learned here today class is... the laws of physics ARE true afterall! Who'da thunk it???
Now, let's see a video where you back both trucks into a concrete post and take them to the body shop for repair quotes. Or a video where you walk into an insurance agent's office to ask for policy pricing for both trucks. Or a video where you hook both trucks to a dead tree stump and see which pulls it easiest.
2013 wins hands down in all of the "practical" categories. You could go back and forth about which truck is "better" until the cows come home.
