I imagine such an engine would instantly blow itself apart in real life. Basically the simulated version of those tractor pull cars where the engine survives for about 500 rotations before it has to be rebuilt.
Depends on the displacement and other factors. Huge engines in that power range like the https://en.wikipedia.org/wiki/EMD_710 are used in locomotives and other applications like power generation where they run 24/7 at 100% load.
