1000HP Vortech Ysi C7Z Goes 8s On Stock Trans/Converter

JTM Motorsports set up this C7 Z06 with a Vortech YSi Supercharger and supporting mods which made a little over a 1000whp.... BUT the transmission and the torque converter are completely stock. After running a 8sec pass right off the street, it appears to be the first and only 8sec stock converter C7Z to date.
