At the point where performance is key this is simple if you use The Force. I’ve had a couple 13B rotary RX-7 engines custom built for me which redlined at all but Formula One RPMs. The power curve was blown through in the blink of an eye and you were off the scale. Pegging was common w/ no rev limiter so who knows how high RPMs reached. Some of my buddies drove their 7s like a bat out of Hell till the apex seals came apart. I drove on instinct and shifted a nanosecond after I felt the power drop – which was something that can’t be charted or measured. It’s an animal thing.

Yep oil starve and crappy oil pump gear. I dry sumped my motor. Takes care of both issues.

I originally addressed oil starvation with AM performance oil pan.
