Thanks!!!

Benefit is more temperature range. If you’re starting at 160* and under load you’re hitting 230*-240* then that’s an 80* window (ie. that much longer you can stay under power before you have to let it out). If you’re at 218* and want to keep it at 230*-240* that’s only a 22* spread.
On the street, assuming all is healthy, you don’t need to worry about it. Most pulls that would land you in jail on the street are likely 3-5s.
Step on the gas pedal continuously for 10s at full boost and all the temps increase. If you’re not hitting thresholds, you’re golden. If you are, then you need to do something. On the road course, it’s brutal as things just get heat soaked.
