What is a good combo for turning high rpm?

Dude, I can show you guys at the strip with less than half 7K runnin 8K and better. Was there a few weeks ago. Done it myself.

This is a road race car. He's up there longer and probably only 15-30 sec gaps between those rpms all for about 15 minutes. And probably 8 of those 15 minute sessions a day.

Not 1/4 mile at a time at the strip.
