Couple C7 Corvettes Running 9 Second 1/4 Mile Passes

Saw these two C7 Corvettes running some nice solid 9 second passes. One at Bradenton, and the other at Palm Beach Raceway. Not sure what's done to either.

Katech just provided info on the first one that went 9.70 at 142.2 mph in the comments. It is a Katech customer car and has a head, cam, 2300 blower, and E85
