im not specifically just talking about 370 VQ37 motors, VQ's in general from the early 35DE's, the 35HR's and the 37s have notoriously weak rod bearings when it comes to strength at high oil temps on track. 250 is like "you're about to spin a rod bearing if you keep at it" even if your oil is up to spec to survive at and past 250, the rod bearing's construction is not

from my testing, ive gotten rear diff temp to about 200 degrees give or take after 4-5 hot laps at buttonwillow raceway park in Socal during 85-90 degree weather,(300 is diff and or diff bearing kill zone) but this is also with my clutch type LSD, which can produce more heat then the stock Viscous LSD. But at the same time the stock VLSD is more prone to failure under heat at a lower temp then mechanical gear type or clutch type LSDs. general rule of thumb to keep diff from getting pissed, is keep you run session hard laps under 15 mins in 90+ degree heat, and under 20 mins in sub 80 degree weather
