it really isn't limiting the power of the motors. since the IFI setup uses pwm(pulse width modulation) the motors are still receiving maximum voltage, it is just the pulse length that is shorter. and since
Torque(transmitted to the shaft) = (Horsepower*63000)/rpm
and since 1 HP = 745.699872 watts
and watts= voltage^2/ohms <--constant in this case because resistance of the motor doesn't change and neither does the voltage.
the total torque transmitted at a given rpm is the same, all that is being changed is your speed. This is the same thing that happens when you push the joysticks only a little bit forward.
we did this this past year and it works very well for precise movements on the field.
although to make a "speed boost" button you would have to be limiting your pwm the whole time except when you want to boost, which would be a waste.
