ther is a seriously blown mid 90's mustang and a Supra with a massive single turbo that is supposedly in the neigborhood of 600rwhp. Other than them I didn't lose a match all night long at stage V so you should be near the top of the food chain for sure =)
Best ET 12.66 at 113mph & 2.0 60' (on bald street tires) Best Dyno 339 hp & 384 tq
