Add ons\upgrades for better MPG?

[Porpoise Hork]

How do I quote this at my gf?

Driving up on/approaching a stale green, or a yellow light and she's STILL on the throttle. She seriously get like 18-19 and I can get 24 ezpz on the same route and take the same amount of time.

This is something I have been trying to get my wife to understand for nearly 20 years....

To this day she can't fathom how I manage to not only get significantly better fuel mileage than her, but almost always either arrive at the same time or in many cases before her when we're in separate vehicles. She does get rather irritated when she fly's up to a light ahead of me and I roll up just as it turns green honking at her as I pass by her sitting there.

If I did that, I would be cooking my own meals for a month.....

not a desirable outcome

Show her the eco-score screen (Acceleration, Deceleration, and Cruse)?







Not like that screen has influenced my wife. ?

I have had it open and she asked what it was. she just said "Oh that's neat" in her unimpressed deadpan voice as she skipped the song that started playing.

She's not a fan of "Honky Tonk Badonkadonk"

I imagine that a Powerboost would benefit from a better Intercooler, especially when driving in a mode that prohibits it from running in EV mode, thus the ICE is getting lower IATs.
But of course the OP is looking for the best fuel economy, so he would prefer more EV miles?

One thing that you have to learn to live with on the Powerboost is higher IATs. Kinda frustrating, actually. When it's in EV mode there's no air flowing through the intake, of course, so the fully operating temperature of the block heat soaks the intake manifold and cooks the stale air in it. As soon as the ICE starts running, those IATs fall pretty quickly, but they are falling from a much higher temp than the non-Hybrid Ecoboost, and they never overcome the heat soaked manifold before the engine might return to EV mode, and start the temp swing again.

I've removed the louvers in front of the Intercooler and was disappointed to find it made little difference.

I agree on the intercooler. Please see (and comment) post 3/4 at OBDLink Data Request Supporting CAI and Intercooler Decisions | F150gen14 -- 2021+ Ford F-150, Tremor, Raptor Forum (14th Gen) | News, Owners, Community, Discussions . Surprised the louver removal is mute.

100F difference between oem and aftermarket intercooler is bold claim indeed. 50F would be pretty bold, in my opinion.
Unless the aftermarket intercooler was liquid cooled I can't imagine that big of a swing.

I can't real comment on the intercooler on my non powerboost truck. I have averaged around 21 MPG Canadian or 17.5 MPG US over the 4 plus years I have had the truck. Most of the time, I drive like a old man, which I am.... I did say most of the time. Like this morning, I was behind a Dodge van, that was speeding, but taken 3 miles to just getting to the posted speed, never mind over the limit. So when I had a chance, I did have the turbos and intercooler doing what they do best. And the white needle on the right was way pasted where it should be and the left one was definitely higher than it should be. I am sure my fuel mileage went in the toilet at that time.....

Sorry for the ramblings ...... long story short, this is my second truck with the 3.5 EB and both are about the same fuel mileage.

Would like to hear from some others of you also, ...... @Buyer2021 ......

Tag acknowledged, but I'm not motivated to offer even academic speculations on this topic

• I don't own a PB
• I don't have 'better MPG' interests relating to my 3.5EB
• Most (all?) of the contemplated tinkering's cross my personal 'don't jeopardize the ESP major mechanical coverage' threshold

Have Fun!

The Toyota Prius hybrid sedans get 45 mpg no matter who or how they are driven. There are many people who compete to get the highest possible mpg with stock vehicles and they routinely get more than 60 mpg. The difference is entirely in how they drive.

Fleet operators of diesel tractors pulling trailers have diesel fuel as their greatest expense. They all want to hire drivers that can get more than 6 mpg with their loads and some average 8 mpg with the same trucks and trailer loads on the same routes and do so day after day.

The big push to auto driven trucks is an effort to increase mpg without needing to find thousands of new drivers. On the plus side it has also encourage fleet operators to hire more female drivers who are more efficient in general than the men.

I think the difference is mainly just how the vehicles are built and what they are made for. The prius is made for fuel efficiency. The PB is not. It's a nice little benefit and many of us have figured out how to take advantage of it even more. But I think they did it mainly for bigger power numbers, a hell of a utility truck with ProPower on board, and to test the market of a hybrid f150.

My wifes 25 Kia sorrento hybrid has a bigger electric motor than my PB. I think in the future assuming they continue with the PB which I am most certainly sure they will, I think we will see even better hybrid performance with the right upgrades.

I have had my 24 PB for a little over a month now and averaging around 24-25mpg. For comparison, my explorer ST did similar routing with an average of 18-19mpg. So far, it definitely has been a boost for me.

Having been tagged, I'll contribute my thoughts, those being open to correction where I'm demonstrably wrong. NA 5.0 here, but realise that air is air and temperature is temperature, regardless of ICE configuration. Also noting the end goal is fuel economy.

1. Boost is actually a measure of vacuum; the engine can only suck as much air as it is designed to do. Assuming that the engine can suck more air through the intake valves than the forced induction can manage, where then is the restriction? It's in the air intake path, including, and usually found at, the throttle body. The piping from outside air up to the throttle body (including forced induction if it comes before the throttle body) usually allows for more volume than the throttle body itself. Enlarge the throttle body and the usual result is more air > more fuel > more hp/tq. This however results in less fuel economy; I'm not telling anyone anything they don't know already but it's good to have the basics laid out.

2. CAIs and intercoolers: if the particular air intake can provide more airflow (up to the point of restriction), this will lower IATs a bit. If the path from outside air to the throttle body is shorter and less turbulent, this will lower IATs a bit. If the intercooler is air-cooled, a bit more. If the intercooler is larger, a bit more. If the intercooler is liquid cooled, usually a bit more. If the liquid in the intercooler was refrigerant, and the intercooler effectively acting as an evaporator (with a corresponding condenser, the air would be a LOT cooler (just like your air-con in the cabin). This would however rob power from the engine to make air cooler and after all that, would not provide any meaningful gain in fuel economy, but in performance (hp/tq).

3. As we know from the experience of many PB owners commenting all over the forum, the EV side is very advantageous in torque and also in urban, slow speed, stop-start traffic. This use case has a benefit in fuel economy. Where the EV side has little effect is out on the open road at cruise speeds and, if one is to cruise in 10th up hills, the turbos will kick in, resulting in the sucking in of more air and therefore more fuel. Especially true for towing, which is why the best economy gains for PBs and EBs when going up hills under load are realised by progressively locking out gears to stop the turbos, and using engine revs instead.

Does the above help the discussion? I don't know.

What is the ROI for any fuel mods. None of the mods are directly saying you will gain MPG. Your likely loosing money from the start. Even if a $1500 exhaust gives a .5, hell even 1 MPG gain how long would it take to break even.

 

[JerseyGlock]

Drag reduction, keep under 70 mph, no tow mirrors, higher tire pressures and premium fuel. Lower the vehicle ride height if possible.

 

[redline]

drive 50 miles/ hour and stay out of boost! you will get killer mileage

 

[ThumperF150]

At my first oil change I added Ceratec Liquid Molly. 200 miles later I noticed a .6 mpg improvement and it appears to be holding.
