If you look at this : torqueCurve { key = 0 150 0 0 key = 2.5 100 0 0 key = 80 0 0 0 } Where you see it says 80? Originally, it was 50 i think?, and then i barely hit 24 m/s, but changing that to 80, it made over 50 m/s ! I changed the 100 and 150 to, but it didn't have any affact, maybe little more acel tho Hope this helps ! (in the .cfg file in the parts folder)
