i have noticed that my stock motors have diffrent amp draws when i use the motor run in on a gfx. what would a higher amp draw signify or contribute on the performance a motor. is it a good thing or a bad thing or just a figure that has no effect.

a higher amp draw usually shows that it is a more powerful motor, more output draws more amps. however, other factors may effect this.

these numbers does help as long as the same equiptment is used to test the two motors.

more amp draw could mean more friction
(more drag) from bushings

i compared two monster horsepower pro stock motors, one with a higher rpm than the other. the one with a higher rpm had a higher amp draw.

when tested on the track, the one with the higher amp draw was miles away from the one with the lower amp draw and lower rpm as labeled in the can.

i also tried this on an mvp stock motor. i changed the spring tension and the amp draw increased, when tested on the track it was awsome.

but hey, you dont need a quicker motor striker, you got some of the fastest already

Can you actually use a multimeter to find out the amps?

You can but you wouldnt be able to use too many volts, i would suggest running the motor with 2 cells for about 2.5 volts, or less may be needed. Most multmeters only recommend a 10 amp throughput, but many can't even do that.

Please let me know how you can measure the amps using a multimeter.

More amp draw means good brushes,meaning you got a good set of brushes and a good contact patch try checking them at 2.0 volts and try to get them meaning monster above the 10 amp at 2.0 volts thats a good motor for touring it all about the brushes try to find some Hurricane gold brushes monster amp draw.....

the 767's i use draw 10-14 amps @ 2 volts but thats with some tweaked springs

Andrew Ellis

On a gfx thats a good motor for sure the springs don't matter that much for amp draw as much as the brushes try the Hurricane gold and see what you get r u running red, red or purple,red...

thanks for the info guys!!! i encourage the others to give your .02 cents worth.

At like 5 volts I'm getting about 6 amps off my stock motors.....(this is on the Integy Octane w/a 10amp PS) I'm woundering why doesn't the motor try to draw more and blow my fuse?

I don't think NO load amp draw means much. Tight bushings or too many shims could raise it up quite a bit.

Amp draw with some kind of load, the closer to the real thing the better means something to me.

10 amps at 2.0 volts is a good stock motor
