I know it has to be source code but is anybody doing this? I ask only because the only thing that cools the pistons is the oil and fuel (why you run rich, oh, and water for some).
I know that on a very hot engine our little 600cc motorcycle engine has conventional oil temps around 250 while with Amsoil 10w-30 our temps stay right around 200. This is on a dc electric dyno under varied load but long on time durations. We have data that proves that there needs to be a fuel compensation for oil temps so I'm wondering if anybody feels it might be necessary or applicable to larger engines. I would think that it does.
It couldn't be harder than a simple table just like the cts compensation (open loop) or IAT/MAT.
I haven't had the chance to see data that shows the oil temp for a small block chevy but from what I have seen, most if not all times the coolant temps will reach and stabalize faster than oil temps. Not to mention highway trips for those of us without oil coolers (yet).

 

And heat transfer to the cylinder walls, I'd imagine.

If the oil temp drops with the other oil, where's the heat going?. Either it's able to shed off more heat easier (or not absorb it), or something else is running hotter.

Are you running CHT?.

Looking at things from over here, it's chamber temp that you want to know. If your going to bother with oil, I'd first have CHT, and MAT taken care of.

 

Good questions but I've got good answers. The oil temps are largely based on reduced friction. Keep in mind that this oil is doing more than just the engine, it also has the trans and clutch (although clutch is locked on dyno). It probably has better heat transfer coefficients largely based on it's uniformity vs conventional.
We already have CHT and IAT/MAT. The intake manifold is carbon fiber so it doesn't pick up much heat, actually none since the injectors cool down the ends of the runners .
We also have a high speed port transducer to measure individual port pressure waves. It's pretty cool when your engine has the ability to rev up to 14000rpm.
I guess it's a waste of time. I just thought it would be cool to compensate. Oh, and Oil temps like you pointed out, tell a lot about the combustion chamber temp.

 

I wouldn't brush it off so quickly. If there is a large enough fuel correction required from a change in oil temperature then it would be worth implementing.

Even better may be to have a SA compensation tied to the oil temperature. For a max effort engine it just may make a difference.

How much actual change in temp is there?.
