Default Motor Amp

Can someone enlighten me on this?
Ive been toying with my LRP Pulsar Comp. 3's volt out. Setting it to 7.2 and powering my mabuchi johnson with it gives me different reading to my 4 stock motor.
1. 1.13 amp
2. 1.05 amp
3. 1.09 amp
4. 1.25 amp
of course these are the average reading of these motor.
My question is, Will the motor with the highest reading the best to use? I'm confused because the motor with the 1.05 reading is my newly break in motor. Does that mean I did a bad job of breaking in my new motor? please help.

No load amp draw has nothing really to do with how a motor will perform on the track. The motors with the higher amp draw might have some binding in the bushings. The only way to know what motor will perform the best is to put them on the track and get some lap times. Or use a load dyno for testing and that is subject to interpretation too.

So gear them all the same and run 3 laps with a fresh batt. then recharge and swap in the others. The one with the fast laps will be strongest.

Or (shameless plug) just order a tuned motor from teambrood.com.

Thanks for your input. Im using a stock mabuchi motor because I'm racing in a spec class where in only mabuchi/jhonson motor is allowed.

If there's other ideas, i want to hear it.
