cobra was on a higher rank than racer and erza beat cobra. also, we did not see racer fight against erza, so we cant say that she will lose. in fact, the first time they fought against oracion seis, it took three of the members to take her down, cobra racer and hoteye, not to mention she lasted the longest. the first time around, racer's power wasnt actually speed, so it wasnt a battle of speed rather just him slowing them down, so the only method to beat him would be gray and lyon's method.
