I have found a formula that works using the power figure to calculate torque

Torque [Nm] = 9549 x Power [kW] / Revs [rpm]

so using the graph where peak torque is at 4000rpm

Torque [Nm] = (9549 x 127 [kW]) / 4000 [rpm]
Torque [Nm] = 303Nm at the wheels

so then it has 223ftlb at the wheels
Thanks man, and that number is crazy.
