My car is a track car only. No oil cooler and it has been on track since it was 70 miles old. Currently has header, no cats and a Borla exhaust, intake, tune, suspension, all the usual sutff. Running 0-40 Castrol Edge I can guarantee that the oil will be between 248-257º, depending on ambient temp. Other BRZ/FRS guys see higher temps than I do, I have been doing this for a long time, I am not kind to my car. Oil pressure never drops below 50 psi. Will I spin a bearing eventually? Probably, but the car has 14,xxx miles so far and I just doesn't seem to care what I do to it. I might go up a grade on the next oil change to see what happens. I personally don't think doing 20 minute DE sessions under these conditions is doing much harm. Racing would be a different story.
