Dyno result

Even though your oil temp is climbing, look at where it started. It looks like they started with a relatively COLD engine, so it's obvious that the oil temp is going to climb. I wouldn't call 217 high, but I'm no longer "in the loop" as far as proper engine temps. You can see that once it went up to 217, it dropped, meaning you must have a 210-ish(remember, they have a manufacturing tolerance) thermostat, or maybe evans coolant (look up the crazy specs you run with that, they don't even have the fan turn on until about 217). Point being, your coolant temp went to 217 at 1506 rpm, then dropped, meaning the radiator did it's job for the remainder of the run. As far as oil temp, back when I was wrenching in cats and trucks, an old mechanic had us REMOVE the giant luberfiner secondary oil filters on our diesel trucks for the sole reason that they kept the oil temp too low. Engine oil needs to be past the boiling point of water in order to cook off any moisture on your oil, plus, it kept good, stable pressure all the way up. If your oil temp was up in the 250-270 range, then worry..a lot. Without seeing the EGT's on this, it's only half the story, they would really clarify what's going on here, like why the boost pressure drops after 1500 rpm. If the truck were equipped with them, that's what I'd be watching in the truck on a hard pull, and call the rest of the readings fine. Big picture, oil temp at 223 and coolant at 217 are OK if it was MY money buying the truck. BTW, I only post this from the view of a guy with mechanic and dyno experience, but not OTR experience, so take it for what it's worth. Good Luck

 

Also don't forget that for every lb of psi on the cap you gain 4 deg of boiling point. I'm not a fan of temp but it's needed for emissions to get a clean burn.

Good luck.....
