    Take more cool down laps.
    Make sure your oil cooler isn't restricting (too many 90 degree bends in lines or kinks or hoses too small)
    I go at least -10 AN

    I race a 6 lap not to big. A track maybe 6 mile track on my 3 lap am already on the 280 oil temp and my oil cooler is a 21 row with a fan and a 10an hose lines and no 90 degree bends only two rest are straight just my problem when I floor it the temp goes high but if I take it easy and don’t pig it not a problem when I feather it or take it easy

    you know this is the drifting sub forum right? 6 laps on a 6 mile track... I don't think most of our cars see 36 miles in a season.

    with that said, hows your ducting to the cooler? I know ducting is everything on road race cars.

    most high-ish power drift car builds struggle with keeping fluid temps reasonable after a few hot laps on a sub-mile course. the difference between driving a sub-mile course intermittently and driving a multi-mile course for multiple laps is tremendous. go ask this question over in the track build forum, they will probably be of more help

    I would look into getting a crank scraper. That can dramatically lower oil temps and free up a bit more power. If you have the budget a dry sump would be even better.
