My Skyline.
1060hp
Max Speed: 224.6mph, it got to 222mph on the Test Course straight away, so you figure that the straight aways on other courses are about/shorter than this. Compare to the F/687 top speed of 212.8mph and
400m: 9.528 seconds Just to show you the acceleration. Compare to the F/687 of 8.908 seconds.
I didn't set these gear ratios differently for either car for each set. Also, the F/687 gears are a little messed up from me and a friend trying 400m times and not saving original settings. Also, the Formula car had 914hp.
Gears ratios:
1st: 4.002
2nd: 2.680
3rd: 1.950
4th: 1.489
5th: 1.193
6th: 0.876 (could probably be made a little shorter)
Final: 3.300
