My fully built Mustang with her Vortech YSI blower at over 22 lbs of boost was wicked fast... NOT a corner carver though lol
Fastest I've been in the Z is 153 mph - still room left... here was the GPS readout (in km/h)
I also did the Petty Driving Experience in Vegas on the 1.5 mile track - at 150 mph gotta love those turns! Even got to lap another driver who was doing 134
