I just tried using my widebody, Escudo-swapped Mitsubishi Lancer Evo X for a couple of the Evolution Meeting events that are required as part of the respective Bonus Menu, since I hadn't done any of those events yet. (Specifically, the rounds at Colorado Springs - Lake and Monza.) I also hadn't tried using this particular build yet, which comes in at just under 700 PP on Sport Softs. Oh man, it's a blast! Now I understand what turbo lag is, haha! Yeah, you definitely need to try keeping the revs high to make the most of it, even if it means shifting a gear lower than I would for most other cars. But once it hits a certain RPM threshold, it just blasts off like a rocket! (Perhaps this is a more pronounced example of an engine's "power band"?)
EDIT: I wonder how this thing would fare in a drag mission, especially with the torque ratio set to 50:50? I bet it'd smoke most things!
