There's nothing wrong with your engine. The very fact that your temps are up, says you have complete or as good as it gets combustion going on. If you didn't have complete combustion, you would not be able to pull a sick whore off a piss pot with that vehicle, let alone pull a load up hill.
Like CW86 above said, you're burning fuel because of the load, and it's heating up your exhaust gases, and in turn the turbo, and the turbo is transferring some of the heat to your intake air. No magic, and no getting around it, and no reason to be worried. That engine does not care if your intake temps are 150 or 250.
Your Ford truck, they put that on your engine for one reason, to increase FLEET MPG average. All car companies have to meet a certain MPG set by our gooberment, and now they're trying to squeeze every mile they can out of an engine. I don't remember exactly, but I think the new standard is around 50 MPG for the fleet average, but don't hold my feet to the fire on that.
The slight difference in the air density can only be seriously realized over a large fleet like a manufacturer or over the road trucks putting on 100's of 1,000's of miles a year. This is what it was made for, over the road hauling where truckers put on 100,000 to 150,000 miles a year. Now that slight 5% increase means slightly better MPG, and at 150k and maybe 6 MPG for a trucker, that means he's burning 25,000 gallons of fuel a year. If he can increase that by 5% with an intercooler, he's getting 6.3 MPG and burning 23,809 gallons of fuel for a savings of 1,191 gallons which means, depending on fuel prices, between $4,000 and $5,000 a year in fuel savings. Here an intercooler starts making serious sense, but for a Roxor.....well, to me, the juice just "AIN'T" worth the squeeze.
That engine does not care really what those intake temps are, because they'll never get high enough to matter. Before they ever do, your turbo will cast her withers because the exhaust gases will need to just about melt that thing before intake temps start to matter.
As far as engine coolant temps, again, as a great philosopher once said....."SO?"
I mean at 220, that's nothing, even 250 isn't a big deal if there's a real reason, like you're working the engine hard like pulling a load up hill, and once that heavy load is reduced, the temps come down.
Cooling systems have pressure caps, and most are 15 PSI. What that means is as your coolant gets hot, HEAT cause coolant to expand, and HEAT is what builds up the pressure, not a water pump. The coolant, as it gets hot, it wants to boil, but it can no longer boil at 212 like normal, because of your pressure cap.
For every POUND of pressure in your cap, you RAISE the boiling point by THREE DEGREES. So, with a 15-pound cap, you've raised the boiling point another 45 degrees, so your new boiling point goes from 212 to 257 degrees.
If your engines coolant goes beyond that point, the cap releases the excess pressure and coolant flows into your overflow tank, and not on the ground where you lose it. Once the engine cools, and the coolant returns to its normal state of volume from where it had expanded from when hot, the coolant is sucked back into the radiator and cooling system because the shrinking coolant creates a vacuum in the system and the vacuum valve in your radiator cap opens and lets coolant flow back into the cooling system from the overflow tank.
This is why you NEVER remove a hot radiator cap. When you do that, you instantly lower the boiling point back down to 212, and it boils out everywhere and you lose it....along with some skin more than likely, but still, your engine doesn't care about 250 or 300 degrees...it just doesn't. I mean that cast iron, and modern fluids and gaskets, it's not a big deal. I mean I wouldn't make a habit of it, because it is reducing the life of fluids to some degree, and reduced fluid life, can mean reduced engine life if let go too long, but for pulling loads up hills....no biggie. She's doing what she was designed to do. When you work, you get hot, when your Roxor works, she gets warmer, and neither of you will die from working hard and getting warmed up....well your Roxor won't anyway.
I hope this helps.
