You Break-In the engine at WOT on the specially designed Break-in Bench, that comes with a tuned propeller for that purpose, the necessary takns, with the procedures set by every manufacturer that suggests that method.
You finish your Break-In process at the track with recomended procedures.
You don't WOT your car on the starter box, because it doesn't give proper load on the engine.
What some drivers that don't have a Bench do, is run-in the engine on the car with flywheel, clutch, and gears, over the starter box at a throttle position and rich mixture enough to get the engine to at least 90°C, and do the first tanks like that, and then finish the process at the track.
