There are no 2 motors have 100% identical power output, even they are the same model, still there will be power diff. Also, ESC will causing performance different, so beside tech motor output, are you going to tech ESC as well? How about battery? Drive train efficiency?
Tech performance is just impossible in realworld limitation. Tech on construction is the only realistic solution.
Hell even handed stock motor race will have something like "damn my handed motor sux, yours is better"... HAHA
