Default cutting the comm?

I have 3 p2k2 and all 3 are different sizes
.291
.277
.287

How far can I cut them before I lose torque and speed?
Please help!!!!

I have received some of these motors as trades and want to get them up to racing order!
Thanks.

The smaller they get the faster they will be. At big events we cut all of our hand out motors to .285 even before we run them the first time. As the comm gets smaller you get more brush overlap and more rpm.

I dont do this at club races though as you kill about 2/3 of the motors life.
