Chicago tuner breaks 9-second mark with Nissan GT-R

AMS Performance of Chicago, holder of the fastest quarter-mile time in a Nissan GT-R, has set the bar higher with an 8.97-second run at 169 mph.

According to AMS, the run also grabbed the fastest 60-to-130-mph time, at 3.34 seconds.

The Alpha 12, the shop's flagship performance package, cranks up the GT-R's output to 1,500 hp. Yet the GT-R keeps its full interior and air conditioning.
