A 9 second capable GTR beating a 10 second Bugati, it's not out of the question. Bugatti is a 140mph car(1/4 mile), it's very possible the GTR is a higher mph car then that.

EDIT(adding #'s)

Bugatti:
0–100 km/h (0–62.1 mph) 2.5 seconds[11]
0–160 km/h (0–99.4 mph) 5.5 seconds
0–240 km/h (0–149.1 mph) 9.8 seconds
0–300 km/h (0–186.4 mph)[12] 16.7 seconds
0–400 km/h (0–248.5 mph)[13][14] 50 seconds
Standing quarter-mile (402 m)[14] 10.2 seconds at 230 km/h (142.9 mph)

Modded GTR:
An AMS GTR went 146mph in the 1/4 mile in March(with a 9.9 ET). With the speed of development of the GTR platform currently, who knows what the highest trap speed is currently.
