them cobalts are tough. i ran one a few times (my cousin has one). his is modded (intake,exhaust,tune) and is pushing about 210+ to the wheels. i have APR 91. from a dig i got owned by about a car and a half until we let off at 100 the first run. the second i got a better launch and stayed neck and neck until turbo spooled in second and i was :burnrubber:. they hit boost instantly which will fuck us if we dont launch right. we went from a 30 and 50 roll as well, both times i pulled about a car on him. the s/c whine is real nice with the intake though, and with these 2 cars it really comes down to drivers!
