Keeping temps down

[pablo94sc]

No, not temporary workers. After seeing some AUS before and after IAC temps, seems like upgrading the intercooler and pipes is a good idea even if you aren't planning on other go-fast mods. One air-to-air cooler kit kept the IAC temperature near ambient after 3 dyno pulls. That's pretty impressive if you ask me.

Also thinking an external transmission cooler (and locking dip stick) should be on everyone's list to add after watching my trans temps reach >210°F on more than one occasion while running hard. I don't want to see those temps over 200 ever, and preferably <190. Anyone else notice their trans getting too hot for comfort?

Thoughts? I'm all about making power, but with the truck already being a hoot, I'm more concerned about consistency and longevity.

What choices are you looking at for intercoolers?

I'm not sure. It was a YouTube video where the company did three pulls for a baseline and then three after they installed their kit. Shouldn't matter if we use theirs or not if we can figure out the core and endtanks used. The pipes are a different story.

Regarding the transmission temp, here's a pretty good article describing the 10R series transmissions and a quote from that article:

https://gearsmagazine.com/magazine/...0r140-10r80-and-10r60-the-same-but-different/

The normal operating temperature range for the 10R applications is 195°F to 215°F (90°C to 101°C). Yes, this is the OEM specified range, so don’t correct it. Everything from the friction and steel plates to the fluid is designed to function at its optimal level when the unit reaches this range. So, on a hot Arizona day, when you are pulling a 40-foot trailer uphill to the lake, it is common to see temperatures spike as high as 230°F!

Cobb makes an intercooler that I was thinking about picking up. Currently my charge air temps run about 30* (40* on a really hot day, gotta love Arizona) over ambient and climbs pretty quickly at idle. The intercooler was one of the best mods I did on my Focus RS, I am curious if I would get the same results for this truck. I just don't want to be the guinea pig when there isn't much data around their efficacy yet. Especially considering these trucks were already designed in hot environments.

I put one of these trans coolers on mine, I also didn't like temperatures of 95c and peaks of 110c or more.
Since putting the cooler in it now ranges between 65 and 90c.
No adverse effects after 17000km.

The charge air temps are also an issue, before installing a new intercooler i want to understand what the louvres on the front of it are for and when they are open and closed. I might trial it with them removed and see.

Anyone know what their purpose is?

Might be the case, but getting that close to peak "normal" operating temp isn't going to let the transmission (fluid) last a long as running consistently near 195F. And let's be honest, Ford isn't known to have the best transmission reliability of the major brands. I'd rather err on the cool side than the hot side. Having your trans crap out on a road trip or while off roading isn't fun!

I had the same concerns, and didn’t want to run a different tune without doing something about it, so I bought the COBB intercooler.

I don't think mine has ever gone past 194°

Edit: it 203° the other day after an hour and half commute, a good chunk of the time in 3mph stop and go traffic.

The shutters in front of the radiator? That's the active grille shutter. They are used primarily to improve fuel economy by reducing aerodynamic drag as well as shorten the time it takes for the engine to warm up.

It increases fuel economy by redirecting air around the vehicle when at speed.

Aftermarket FMIC deal with cooling turbocharger/compressor intake temps only, which aids in hp production. They provide no other cooling benefit to engine to defeat heat-soak.

IAT‘s are irrelevant when it comes to turbocharging. Once you‘re moving over 5 mph, IAT’s are typically and quickly reduced to ambient. The FMIC helps to produce a cooler, higher density air charge to the turbocharger. Thus providing greater cylinder compression and additional whp, at sustained cooler temps. Used in conjunction with higher boost pressures.

Properly R & D’ed, manufactured and mounted oil and transmission coolers, typically provide direct benefit to cooling system operation and help to contain and reduce higher temps associated with increased boost and heat-soak. Heat soak being the enemy of hp production.

All three will aid in greater hp production, protection and longevity for the engine. Typically, the engine oil needs to run around 205-210 F degrees to evaporate condensation in the crankcase. Less they won’t, which can cause internal corrosion and damage.

Oil coolers are equipped thermostats plates to keep operational temps within these desired norms. Trans cooler generally are not at all and benefit from unrestricted operation.

You can’t go wrong with the addition of all three, if your wanting to up the anti in whp production.

That makes a lot of sense. I will go ahead and trial removing the stutters and see what happens to intake temps.
I have seen up to 75 degrees c intake with only 20 degrees ambient so I don't trust that the shutters are closed at times that they should be open.
May see if I can find a PID for shutter position and log it first.

Test and let us know! Fyi, the lower grille shutter is used for managing charge air (boost) temperature.

I did some data logging of charge air temperature vs ambient.
Initial findings are that it seems Fords strategy is to modulate the intercooler shutter operation in response to engine load. It's definitely not ideal because it doesn't keep the shutter open until charge air temps return to normal, it closes shortly after load is taken off.

For example,
-driving at highway speed.
-ambient air temp 20degreesC
-air charge temp 30degreesC
-shutters closed
-Full throttle pull for 5 seconds
-shutters open, this can vary as a percentage, not necessarily fully open.
-air charge temp increases to 45degrees C
-close throttle and return to highway speed
-shutters close within 10 seconds while the intercooler remains heat soaked and air charge temp elevated at 45 degreesC

The issue I see with this is the shutters ultimately prevent the recovery of a heat soaked intercooler, so the next time you go to WOT your starting with air charge temps that are signifcantky higher than the previous run.

I will do a bit more investigation, but it's leading me to remove the shutter.
