Dear takahashi,

There could be a problem with the data on the charts. 597,9 Nm @ 5798 rpm equals to 363 kW (about 490 hp) @ 5798 rpm wich is not possible. Torque figures shoud be in the 200´s Nm all around.

Would you please ask KS for clarification?

Regards

That torque figure is tractive force. It has to do with the diameter of the rollers. From memory with these Dynos (Dynamic Test Systems) you need to divide by about 3 which would put it about right.

As taka mentioned, euro and aus spec cars share the same ECU and there are 2 known types here. Mine turned out to be the one they hadnt seen so I missed out . I am going to be sending mine to Japan for then to look at.

My 03-model is a 4AT version. Knightsports RE-flashed it but it was a little erratic on the AFR so they need more work on it at this stage.

Would love to see a 5kw gain like Taka scored from them..

Knightsports guys DO know their stuff

The absolute figure can be magnified by the differential too. That is why it is higher than the actual figure at the engine in the first place. Different dyno will have diff figure because of their set ups as per auzoom said.

It is much like Power is less than actual on the dyno (much less in my experience), and torque is much more.

It is no way a 124kW at the engine car and it is more powerful than some of the lighter but same power 124kW atw car I have driven.
