Technical question for Sears Point
 

Hey folks, for those of you that have driven your twins at Sears Point for a day like HPDE, if you were keeping an eye on oil temps, what were you seeing? Also, an idea of what your setup was at the time would help as well - I'm thinking of driving down for either Thunderhill or Sears Point this year, and while I know I'll need an oil cooler for Thill, I don't know if I'll need it for Sears Point or not.

Any help would be appreciated!

Why would you need one for Thunderhill and not Sonoma?

Oil temps go up pretty fast for any performance driving. Temps can get higher than what would be considered safe for the longevity of engine life even when doing canyon roads. This is for a stock engine. Ideally you don't want to surpass 235° F. With an oil cooler you will stay well below that.

I was assuming that the ambient temp differences plus the track design would also play into the overall oil temp, with my experiences on Thill and much more time spent full gas compared to Sonoma, where I really only ever went full gas coming out of turn 11, but then again those were in different cars and not in the BRZ. I'll err on the side of caution though. Thanks.

Oil temp is RPM related, not WOT related. Lets get you an oil cooler before your trip.
