Keep in mind though, these temps are on an older 300zx Non Turbo. The oil temps on a newer 370z are going to be higher. The 34 row oil cooler seems to be doing its job if you are only seeing 200-225 @ 100 degree air temp. How long are the run sessions for? An ideal oil temp is really between ~ 185 on the low side and ~200 to 210 on the high side.
In the case of the 370z. Just being able to prevent the engine from going into "Limp mode" and away from the 280 degree mark is ideal. I have heard cases where people all over the country get their Z's to react that temp just in a spirited mountain drive.

Thanks for the clarification on the 300zx. I didn’t realize that.
My run times sessions are 25 minutes. In the spring when the outside temps are less than 90 degrees it indeed runs in the 185-195 degree range. On those summer days when the temps are over 100 degrees and the track is well over 150 degrees, 225 was the max I have seen.
The cooler is a must as you know if you track the 09-10 Nismo.
