Low Gear: 24.0:1
High Gear: 9.4:1

so just divide motor rpm by the gear ratio for low and for high and you'll get your answer. Of course, if you're using a different AM transmission you'll need to get the numbers for that one.
just another note, the supershifters came with a 48:17 final stage option also.
