I dunno about all that. I'm pushing the car to the limit it can handle on the stock suspension. 280 deg oil temps, 230 deg water temps, 102 deg air temps from my last Buttonwillow CCW1 track event. This is with upgraded oil cooler + radiator too btw. I have to do cooldown laps between hot laps, simply because the car will push rev limit down to 6000 RPM. This is "normal" for me. 148k miles, 40 track events on original bearings.
This was my best lap of the day, taken during the heat of late afternoon - so very hot. You'll notice I had done cooldown laps to get the oil temp down to around 250, then they spike up to around 277-280. If I had gone for another lap, I would have gotten temp warnings:
(mute the sound, mic is cutting in and out which is annoying)
