Indian - I wouldn't doubt that something would fail in the course of a day. If he's jamming that engine for a good while, I'm sure something in the cooling system would be 1st to go. A V12 redlining all day long has to produce astronomical amounts of heat. And also if you keep redlining it like that guy was in the video, it would heat up even quicker, because if it's operating in that RPM range at such low speeds, there's not much cooler air being moved under the hood, which will cause the temp to rise pretty quickly.
