If you need to retain your current ratio, though, try code like this (pseudocode; will not compile in anything; you need to run this as a separate task, or integrate it in to your main loop such that it is executed without an explicit wait)

//5 for all of the values is arbitrary. For faster revving, go with 10 or so.
IF(abs(motor_power - desired_motor_power) < 5)
    motor_power = desired_motor_power;
ELSE IF(motor_power > desired_motor_power)
    motor_power = motor_power - 5;
ELSE
    motor_power = motor_power + 5;
WAIT 100 milliseconds;

If implemented, this code will get you from 0 to 100 power in 2 seconds. If you want to go from 0->100 in less time, increase 5 to anything you want. It is *highly* advised that you not decrease the wait time much, because if you go from 0->100 in 20ms, there's hardly any point to a revving system.

you'll have to really control it because if it's to strong you'll be disqualified.
