the reason that the graphs should cross is at this point 1 hp = 1 ftlb. i had a quick look but cant see anyhing over than how they have worked this out from what James watt worked out.

what i did find out is the formula given before ( [torque (ftlb) x rpm] / 5252 ) but with the full figures not rounded is used by dyno to work out the horsepower. which does make sense as your turning the wheels on the dyno and torque is the turning force

if i get a chance this afternoon al have another go at searching for info on it
