I won't buy into this as mine (and 2 others with similar mods) put out about 155 on the dyno. We had no PC's though but I struggle to think that would make much difference with slip ons and its proven there is no gains with a K&N...
Anyway, HP is actually torque (ft lbs) x revs divided by 5252. The torque and HP graphs should always cross at 5252 rpm. The first dyno sheet looks OK based on this, but the second dyno sheet looks like the torque is reading a little high.

Depends on the units and whether the scales for both are equal. For Nm and kW and equal scales, the crossover point would be at 9549 RPM. I can provide proof.

Yep, I'd say the fact that the 2nd dyno is in Nm may be why the torque reads higher.. the conversion makes em similar.

Power kW = (Torque (Nm) x RPM)/9549.3

Power HP = (Torque (ft/lbs) x RPM)/5252.1

1ft-lbs = 1.36 Nm

1HP = .75 KW
