Just curious how long it would do it. It's going to see a heat issue running that hard, just was wondering how long it would take before that heat presents itself. I'm not talking about absolutely grenading, as I'm sure Elon has something to shut it down before it kills itself.

Heat mitigation is a much larger concern with an ICE making lots of power. An ICE will put approximately 30% of it's potential energy into forward momentum with much of the balance being lost to heat as well as other factors. Teslas in particular put more like 90% or more of their energy into forward momentum. This means that next to zero is lost to heat so even if you double a number that is nearly zero... you probably get the point.

True, but ICE vehicles are built with larger cooling systems in place since they so generate much more heat. But at 130mph, there's a metric fuckton of air moving through the radiator on my F150, and around the trans/diffs/etc.
Now I've never actually inspected a tesla or anything, but I would assume that it's a relatively flat bottom, so not much moving around down there, and has a small radiator stuffed somewhere to account for cooling the battery and whatever control systems are in there. I would ASSUME that the discharge rate needed to propel the vehicle would heat the pack up a bit. Same for running back to back launches in Ludacris mode

Tesla drive motors have their own cooling and it's not really an issue ever that I've heard of. I remember seeing something years ago about how they torture tested these drive motors and what they're asked to do in the car is many, many, many times less.

Teslas have radiators as well to exchange heat, when necessary. It's pretty genius the way it works actually... they have but a single heating/cooling system that manages every aspect of heating/cooling of the car. Unlike the three systems that most ICE cars have it's a single system which cuts down on complexity significantly. One system with a series of check balls and valves to make the magic happen regardless of if the pack is hot or cold and you're calling for the opposite in the cabin.
