Mike's 2022 BRZ

Jfc not this oil cooling isn't necessary/tribology bullshit again.

I'll be interested to hear all about the oil temps and pressure readings for gen2 regardless and seeing how the 2.4 handles things. Biggest thing I've noticed is the straight rods instead of offset.

With or without a lightweight flywheel?

Wrong. With a lightweight flywheel is the way to go!

You need carbon fiber shaft too.

Oil temp gradually gets up to ~272 indicated by lap 5 and never goes up from there. As you can see top speeds and acceleration are not reduced despite much higher oil temps. Lap 6 this session was my fastest lap of the weekend.
No way oil temps are based on coolant temps as my coolant temp always stabilizes quickly (225F I think?) and never moves from there, even while oil temp climbs up to 272F indicated (max 275F from datalogs)

yes stock ecu doesn t pull timing against oil temperature

thanks for the info, but those coolant temps ..holy cow, anything about 220F for extended period of time is alarming for me ..the highest I have seen was 230F I believe and that was on a hot day with a supercharger, IIRC.
I will most likely upgrade the radiator and/or low temp thermostat as well as a different coolant mixture (30/70 maybe)

FA20 had an oil temp sensor, so should FA24.

because there are tons of cars with calculated field/data for oil temps vs actual readings ( most of the Corvettes and Camaros for instance) and it's been ~7 years since the last time I owned/tracked my BRZ so I don't remember
Where is the oil temp sensor located? in the oil pan?

IMO 230F coolant *if it holds there* is nothing to worry about.
FWIW the red mark on the factory gauge is ~250F indicated, halfway between the 230F mark and the max 270F mark.

I've never seen coolant temps rise beyond the ~225F (or whatever it is, could be 230?) indicated at the track, always hits same mark and holds. Honestly if I'm you, if it doesn't try to increase from there for your usage, I wouldn't worry about cooling system mods. If it ever does get to a point where it wants to climb uncontrolled, easy enough to back off and then make mods as required.

From what I've read about C7 Corvette, gauge reads out a calculated max oil temp based on measured oil temp and other factors (possibly including coolant temp). Warning message (and power cut?) at 320F indicated (i.e. calculated). Seems like I've read that corresponds to ~295F sump? Also C7 gives coolant temp warning at 255F IIRC...

Presumably.

I wonder if the factory coolant readout on the 2017+ is inaccurate. I've logged a lot of track days on my 2013 (sometimes as high as 100-104 F ambient) and the highest peak coolant temp I've seen is 212 F, and that's with an oil cooler added to the front of the cooling stack. Oil temps get plenty toasty but coolant temps seem pretty well controlled on this platform.

I would be definitely concerned about that for extended period of track use , oil temps are somewhat less important but coolant temps above ~220s are not.

that is true, they're designed to run hotter when I was tracking my Camaro SS 1LE (2017 and 2019) it was stabilized at around 260F ..the gen 6 Camaros had the actual reading IIRC .. Corvettes are a bit higher and it runs an algorithm to calculate that as well as the Gen 5 Camaros

Went back and looked at data logs, one day I saw 199F max, another 202F max coolant temp. Kinda surprised to see they're that low!

Memory is a little dodgy on this as sometimes I have the temp gauge at "normal" setting with no numbers for *F, and sometimes I have it in the alternate setting where it shows tickmarks at 150F/190F/230F/270F, and they're different scales. In any case I'd see it go up and hold in a "normal" part of the range so didn't think about it much, more keeping eye on oil temp...

Now that makes sense it sounds very normal to me assuming you have an NA car without a giant air-to-oil cooler that blocks the radiator up front.

If you really had coolant temps above 220F, you wouldn't have an engine anymore
