    Is an aftermarket intercooler really worth it for towing??

    UPDATE I just got back from an 8,000 mile round trip, from JAX to Wyoming and back. I pulled a 6300lb travel trailer about 5500 miles of the 8,000, that included a lot of miles at elevations over 6,000ft and some up to 9,000 ft. Over the total trip, average mpg was 10.5. For the most part, I...

    2022 expedition vibration

    Just did the same and the difference in ride and towing is night and day. Driving in heavy rains here in Florida is no big deal either. Great tires.

    2022 Expedition XLT tuner

    I’ve been looking at this a lot and the simple answer is, per your post, you can’t have both economy and performance with a tune. The tuner will sell you a specific tow tune, but you must use premium fuel to get the additional HP and torque - so economy is out. In addition, the performance gain...

    Is an aftermarket intercooler really worth it for towing??

    You are correct, but the louvers in relation to engine operating temps only apply to radiators and not the IC. I wish I could have sub zero air intake temps all the time.

    Is an aftermarket intercooler really worth it for towing??

    You're right - I might be over thinking this, but that's me... I did unplug the louvers. I've had them unplugged for quite a few miles and will keep it unplugged as I see no benefit of the louvers. And around town, aerodynamics is a thing for me. FYI - no CEL either. As stated, I am looking at...

    Is an aftermarket intercooler really worth it for towing??

    First of all, thanks for the dyno chart. That's an impressive result. When I calculate your HP, I come up with approx 650 HP given your 618 ft lbs of torque at 5500 rpm. Nonetheless, a quick and relatively flat torque curve is far more important than HP. I don't want to get a tune because...

    Is an aftermarket intercooler really worth it for towing??

    Today I disconnected the IC louvers by simply unplugging the power source, and manually opened the louvers. I then drove the car to get the intake system heat soaked and did a short half bar boost run. Ambient air was 78 degrees. With the louvers basically locked open, you can see the the IAC2...

    Is an aftermarket intercooler really worth it for towing??

    Well, kind of. But we are talking about work here, not keeping stoichiometric ratio. The engine will be producing more HP per unit, but it will have to work less to maintain ~2400 rpm. This means less fuel. Probably not much, but it will be less.

    Is an aftermarket intercooler really worth it for towing??

    @JasonH - thanks for the Edmunds link. Even though they address the what I think is the radiator louvers, the IC probably applies. And the total frontage the IC represents is probably 120 sq in or so and they are looking for that as an aerodynamic advantage vs cool air charge? Wow. So I am...

    Is an aftermarket intercooler really worth it for towing??

    Any time you introduce cooler air, you increase the density of air, and therefore oxygen. This means, the lower the temp, the more O2 is available, and less fuel needed to do the same amount of work. Therefore, your fuel economy should improve. Why would Ford impede that? It might have something...

    Is an aftermarket intercooler really worth it for towing??

    That's interesting. Just proves that airflow - and supplementing airflow - matters. I built a motor years ago, and to prove my point in how important cold air was, I put dry ice all over the IC (the IC sat on top of the motor in the old air cooled motors). I then dyno'd the motor with the ice...

    Is an aftermarket intercooler really worth it for towing??

    I used to build early turbo Porsche motors (air cooled), including EFI conversions and designing intercoolers to match turbos for each HP application. HP/TQ numbers were 525/520 up to 675/640 on 3.3L up to 3.6L, 2500 lb cars. With this in mind, I am trying to decide whether it really makes...

    Expedition as Long Trip Road Vehicle

    Our 2020 LTD with tow package has 25,000 miles after one year of ownership. We tow a 6,200 travel trailer around the US. We learned these lessons: the car can tow a lot of weight (almost as much as a F150) but this also means it can be overloaded - do the math; I use manual gear selection when...

    Transmission Clunk 3rd Gear

    My 2020 limited does the same thing - clunk when downshifting from 4th to 3rd. I took it to the dealer this week and they reset the adaptive tables and it was butter until today. If I drive around town in sport mode, no clunk. I just got back from a 5,000 mile trip towing a travel trailer and...
