How much torque does an A7 engine produce

[FrogPond]

Colin, the torque and horsepower will cross at 5250 as a function of the formula. At rpms above 5250 the torque can be falling off and horsepower gaining. If the torque curve was still headed up over 5250, the lines would still cross. HP is always a smaller number than torque below 5250 and larger above. It has to do with not only how much coal the horse can haul out of the mine (torque), but how fast too (horsepower). Mike
