I’m super curious what 80100 motors are you currently running where you feel like having more power. esk8, I assume? What’s your controller? Motor amps?
For reference, I’ve got a board with 4x Reacher 7490 265kv motors (see here)
I also race with Jack, who wins pro-class races with two Reacher 7490 179kv motors, at 16s.
I’d be warry of using a water-cooled motor, as it won’t be designed to be air cooled and will likely overheat pretty quickly. (unless you install a watercooling loop on your board, which would be rad)
