OP what did your oil temps go to? Do the new 5.0s have an oil temp reading. That is what you should be interested in, and that is where you'll see the worth of the oil cooler.
I disagree with Mishri about it being a waste, so long as it's doing its job and lowering your oil temps. Your coolant temps rising a bit is normal, as there is now heat transference between your oil and coolant.

This might get you back down to the temp. range you're aiming for:

LOL. You got to be kidding me about the whole piston squirter/pump thing. In case you are not, piston oil squirters were removed on the Boss for two main reasons. Correct me if I'm wrong, I'm sure somebody may. (1) They created too much windage at high RPM resulting in a loss of power. (2) The forged pistons in the Boss do not require them.
Anyway, Boss radiator is in. System purged of all air. 50/50 distilled water and Ford Orange. Ambient temps. the same. At idle, AC off, temps climb to 205 then fan kicks on, drops to 195 fairly quickly. With AC on, stays steady at 195-197. Where I noticed the biggest difference was when driving and air is moving over the radiator. AC on or off, temp never goes over 192, usually stays at about 188. Before I would easily see 200 while moving.
A few obvious observations were noticed. Car takes longer to get up to operating temp. Stock radiator is 1" thick, Boss is 1 5/8". Fits great though, nothing like buying OEM. Of course, stock dummy gauge never moves once operating temp is reached.
Can't comment on oil temps. since the Aeroforce doesnt read oil temp. unless I install a sensor.
On another forum, Boss related, I was reading that the coolant temp sensor reading is more like a cylinder head temp rather a traditional coolant temp. This results in readings that can be up to 10 degrees higher than a traditional coolant temp. I may be incorrect, thats just what I read. One poster said he would see his Boss go as high as 220-240 while tracking in hot weather.
In conclusion, I would say the combo of both the oil cooler and the radiator would be your best bet. I bought the oil cooler for its obvoius benefits. Lower temps, more reliablilty under extreme weather and driving conditions and increased engine and fluid life. I just think your not getting the full benefits out of one without the other.

I was in a tour led by Mark Wilson who is engineering supervisor at Ford racing last weekend at Laguna Seca when the Continental Tire Sports Car Challenge was there (a couple BOSS 302R's in that event) and he said repeatedly that these engines are designed to run hot. They start worrying only when the temps get around 250.
