Well, I did the exact setup as Munchen listed and got 877hp...but still won the 'Like The Wind' races with ease. Was first place by the third corner of the first lap on Indy track.
Something else though, I just bought a red Trueno from the used car lot...
That now makes:
2 x White Levin
1 x White Trueno SS Version
1 x Red Trueno
