What is a good combo for turning high rpm?

I mainly race road atlanta but also have been to roebling road, sebring and vir. At any road coarse your going to see those rpms all the time as you go from slow sections to the high speed sections. Dont equate high rpm with high speed at some tracks you may go down to first and hold it through some tight esses or increasing apexs.
Watch the video and listen to the engine you'll hear it at high rpm most of the time.
