Back on subject, I just got back from a trip through the Rockies in a SD pulling a camper. On the long steep grades we were watching the oil temps and EGTs pretty closely. I wonder if the PCM doesn't watch the EGT and cut power when the driver is getting too close to melting a piston? This would explain how a truck can show overheating and not lose coolant.

At first I was surprised too then I seen how much boost is being cut as the motor spins up. The PCM lets the boost hit 15PSI or so for just a second then it starts dropping as the RPMs build by redline it is in the 7-8 range. I have a suspicion Ford is sandbagging on what this motor can do and dumping boost is part of it. I suspect they don't want their Service Departments overrun with people asking why the boost is dropping off when it should be increasing.

assuming their is a pyrometer installed from the factory for the EGT that the computer reads and correct part for boost gauge (don't know much about them) then yes, if not it won't be a plug and play set up.

Did you get the overheat message in the information center of the dash on your trip?

I have a flight computer installed and am going on a trip next weekend. I hope the weather stays hot. The dew point has dropped but we are still over 100. I will try to video the temp gauge as I am driving. Not sure if it will happen with cooler temps and a lower dew point. But we will see!

I found the following in the 2012 Ford Dealer Source Book. There are actually 3 radiators used in the F150's. They are all the same width and heigth but have different core thickness, number of tubes, and/or number of fins per inch. I'll call the three sizes "small", "medium" and "large". But Ford calls the Small, "Standard", when used in the 3.7 or 5.0. Then they call the Medium "Super Cooling" when used with those same engines. Here's the confusing part. Ford calls the same Medium "Standard" when used in the 3.5 or 6.2. Then they call the largest "Super Cooling" when used in the 3.5 or 6.2.
So the Small is only in the lower 2 engines and is always called Standard. The Medium is Super Cooling when used in the lower 2 engines but called Standard when used in the upper 2 engines. Large is always called Super Cooling and only used in the upper engines. Below are the physical differences:
Small thickness - 0.94
Small rows of tubes - 41
Small fins per inch - 15.2
Medium thickness - 1.26
Medium rows of tubes - 41
Medium fins per inch - 16.5
Large thickness - 1.26
Large rows of tubes - 51
Large fins per inch - 16.5
If the same specs are true for 2011, then all F150's with tow packages (regular or max) should have the Large radiator called Super Cooling when used in the EcoBoost. The only other one available for the Eco is the medium which would have 41 instead of 51 tubes and should not be in a truck with any tow Package (according to that Source Book).
Gentlemen, count your tubes!

If I'm reading this correctly...
- EcoBoost non-Max Tow will have the Medium size radiator
- 5.0 will have the Small or Medium size radiator
and
- Max Tow Ecoboost and Max Tow 6.2 will have the Large radiator
If you want the Large Super Cooling radiator you have to go with the Max Tow Package. The regular tow package only gives you the medium size.

According to what Ford850 posted there are two Super-Cooling radiators. A large Super-Cooling radiator and a medium-size Super-Cooling. The large Super-Cooling has 10 more rows of tubes than the medium Super-Cooling.
