The reason why street cars (and occasional track cars) don't see this problem, is because they spend most of their life below 4000 rpm. For cars like mine, they spend 95% of their life from 4000-6500 rpm. The only times mine is running below 4000 rpm, is when it's warming up or under a caution. When you start to explore the 7000-7500 rpm ranges in a 3.0l motor, if the oil pump survives, then count on the timing wheel exploding.
