You're exactly right--this guy has no basis to make these claims. It's internet clickbait.
An new engine development program from a major OEM is a $100M undertaking, and involves thousands of simulated (dyno) and actual (vehicle) engine durability tests. The fact that the S58 torque curve isn't so much a curve but a hard stop at 600Nm suggests that BMW intentionally capped the output in the name of durability, based on a substantial amount of data from their test program.
A few drift cars that can survive a season (on maybe a 100-hour rebuild interval) isn't evidence that the engine could survive for any appreciable amount of time at 1000bhp power levels.
