The Kostov has interpoles. These are electromagnets between the main poles that help keep the fields aligned under high current and high rpm. The other way to do this is to advance the timing to the rotated state. The interpoles do alignment dynamically, so in theory are better at it. The flip side is the interpoles take up room, so the main field poles are smaller.
My old Kostov 11 inch is lighter than a Warp 11 (about 70 lbs lighter), the commutator is smaller, the brushes are smaller, and the brush leads are smaller. I would believe these are the bottlenecks for high currents, not the timing. BTW Kostov says the interpoles help the brushes lead an easier life, so they can handle more current.

i was planning a dual nine conversion can a nine inch kostov take 1000amps and what about 1400amps.
i'd like to be able to max out the soliton if i can, if i my car can handle it. drag racing isn't my primary concern but i'd like to go fast if i need to.
