I don't know how anyone could plan equal peak torque and horsepower. My motor reaches peak torque around 4800 rpm and peak horsepower around 5900 rpm. Below 5252 torque is higher than horsepower. Above 5252 horsepower is higher. Horsepower will continue increasing until torque drops off faster than rpm is increasing.
