GEN 2 Long term FMIC owners?

[nikhsub1]

Depends on your climate , i like the charge cooler having its own dedicated airflow path. I have had issues in summer with large whipple water charge cooler on my GEN1 at highway speed. in the Arizona Summer . Gen 2 i have the Garret CAC , I like my 42deg A/C out of vents and 195 deg coolant temps when its 120 deg ambient .

Yeah I have the same temps even with my FMIC.

So I added the Cobb FMIC and Goostune Stage 2. These are a few things I can tell you for sure. My truck runs considerably cooler on hot days on long desert runs. I use the gauge cluster to see, not actual digital numbers other than what's already posted on various other threads. Here is where I noticed the biggest difference. Towing my boat through the hot desert her in So Cal / Desert Obviously I had to switch the tune from stage 2 to Tow. Going up the summit in the heat pulling my boat before the intercooler used to heat up both my trans and water temps to the point the gauge changes to an actual number vs the needle marker. Since adding the FMIC I have not heated up once going up the hill in the heat.

People seem to refuse to believe science and physics. I have done testing on this very subject. Stacking heat exchangers gets dicey when the fin density of the leading exchanger is super dense. This is not the case with these FMICs.

Ok, let’s see some sciencey stuff then! Since early 2020, I will no longer commit to “Just believing the science”, since science and scientific method, like sex, have different meanings now, than what they used to.

The sporadic overheating threads are difficult to find on here and I remember one of the more popular threads being a gent who had both lights and FMIC + towing equaled overheating.

And the point about stacking.
so your radiator is capable of cooling your truck in all conditions as delivered. You mount an FMIC and reduce the CFM to the radiator now - maybe minimally, maybe slightly, depending on how dense the the FMIC fins and tubing is. In addition to the obstruction, you’ve also increased the temperature of the air going into the radiator. Again, maybe this is a slight increase, maybe more than slight. Unless the FMIC is magically lowering the exit air temp below ambient.

I believe we’ve had towers with just the FMIC report overheating concerns, without front mounted lights obstructing airflow - you cannot mount the S8 behind the grille with an FMIC, so they would have to be bumper mounted, pretty large and centered or blocking the air into radiator.

I think we also had a middle east user who had overheating concerns with the FMIC, as he was Raptoring in soft desert sand.

These scenarios are high load, low-ish speed. If you’re able to maintain speed with a higher load, you can make up for some airflow loss and increased inlet temps, but to a point and I don’t know what that point is.

Hard data and controlled testing would be great.

How could it run cooler? Do you think its the extra airflow removing the grill slats? I read about certain tow ratings being governed by or companies opening grill size for just the reason of sufficient cooling to reach a given tow rating. So in the absence of an actual raptor engineer proving it just becomes anecdotal evidence , wouldn't you agree? Im on the fence with front mount vs stock mount as well .

 

[nikhsub1]

FMIC will give you better IATs than stock mount, likely less pressure drop as well. Cooler IATs are where it's at

You guys are not getting it. There is only so much cooling available at any giving speed. In others words, air flow will be the same no matter what cooler is where. So all you are doing is trading where you are cooling the most. If you install a FMIC you will have the coolest air to make more HP, but risk overheating because the hot air from FMIC is being used to cool the radiator. If you use a factory location, you will not make as much HP when hot, but will not overheat the radiator.
It’s just a trade where you put your cooling. Your BTU removal capacity is fixed by air flow so you can decide where you want the best cooling.

Yeah I have the same temps even with my FMIC.

Yeah you don't have 115 ambient. Your in Los Angles sitting in traffic your fans doing all the work. Fmic not worth a few degrees lower IAT to me .

No but during the summer we roadtrip from here to Colorado with stops all over AZ, NV and UT - in 115 heat. No issues but you do you.

No issues with Gen 2 at all. GEN 1 yes I did but now have the smaller cooler no more issues.

Is there any ford production vehicle. Besides SD diesel ,running stacked cooling and intercooler ? Anything I can think of had the CAC/HE in seprate lower location than the cooling package. Gt500 ,raptor R , gen2 lighting , Focus RS. Diesels do it because the have a ton of surface area to work with. Huge radiator and huge CAC. Few percent gain in efficiency/ IAT not worth to me in AZ . Would like to see some real world data . 100 deg day . Iat2 , cooling ,ac vent temps. On same truck . Same day . Both types of CAC tested. Plus 1/4 mile runs.
