How to calculate the graph

The Skyline from Duplode was calculated with a ratio of 6.5

I don't remember exactly which correction I applied for that, so let's pretend it was a 16,67% (1/6) change. Applying the correction and converting to N.m, we end up with 4*1.356/(5/6)= 6,508 N.m

It seems my guess from the earlier post was right, then 

One observation about the Skyline: while I have accidentally left the 6th gear ratio defined in the RES, it only has five gears. That also means the flat track top speed is a little higher than 166 mph.

Remember the Japanese Gentleman's Agreement, all the car made 280 HP...  Officially.... Because in real...it was much.
