One little half-mile open stretch with some nice curves came up, and I burned through it at the limit and then accelerated up onto a highway ramp at full throttle. Checked the oil temp as I was bringing it down to a good coasting speed on the highway: 255F. Then I backed off and cruised in 7th under the speed limit a while to get it back to 230.

There's nothing wrong with 255 really, as an occasional burst, but I wouldn't want to sustain that kind of temp, as it affects oil viscosity and oil life. So right now, in the interests of keeping the oil (and thus the engine) in good shape my driving is limited by oil temps. I have to back off and let the car cool occasionally, and/or I have to pop the hood and fan-cool the car when I get home before I shut it down. I don't want to be doing that, and frankly shouldn't have to. Luckily the aftermarket has fixes
