Default Run cooler, longer?

I'm currently running 17Radon motor - for drifting.
If I switch to black can sport tunned (19T)
Would it run cooler and longer? Less amp draw?

Black cans are just tuned 27T mabuchi motors, so it'll be taking much less of an amp draw, as well as be a bit slower.. they max out at 21,000k.
The only problem with those motors is that the brushes are pretty soft, don't last too long.. They're prone to burning up as well if overworked.

I have to disagree about the brushes. The brushes on the Tamiya Sports Tuned are hard. I heard of people running then in for 10 hours and longer just to bed the brushes in. I have one that I use for enduros where I am and it has done about 2.5hours and it still fine.

But I have had them go soft if they get too hot as previously stated.

And I thought they were 23T motors with zero timing.

Oh, maybe they could be 23T.. I just figured it's a tuned version of their silver cans..

Maybe I'm just too hard on the throttle and brakes for them to last long enough for me

Had a friend who popped a new one in his car, ran for 5 secs, and it slowed to a stop.. he picked the car up, and the brushes were glowing bright red.. hah.. needless to say that one was a goner..
