For what kind of vehicle? How big? How many cells do you plan to run it on?

It is necessary to build a very fast car 1:10
I know that you can overclock the standard BLDC motor.
For examlpe
BLDC 100000 rpm (0 min 40 sec)

But I do not know what to do to use.

That doesn't help really... how many volts/cells do you plan on running? What kind of car; touring car, truck, etc?

Finding a motor that will survive at 100k rpm for a while won't be easy, most don't have bearings rated for that speed.

The brushes won't last long, either. Why do you need such high rpm, when low rpm and more torque would last longer?

Blanket question. Answering it is a waste of time and forum.

BLDC = brushless, so no brushes to worry about.

Sorry, I'm not up on all of the buzzwords. Now, if it was a heli....

But, I still wonder why you'd need that kind of rpms, is this going to be a ducted fan powered car?

I'm at a loss for that too, 100k rpm is insane. It'd be better (and easier) to run different gearing than rev a motor that high.
