I haven't updated this in awhile, but I made it into the 9s a few months ago and to date it's still the ONLY C7 ZR1 in the 9s at 140mph with full ZTK aero too! I realized after the rad had an air pocket after the 160 t stat install too, so I'm heading back to the track tomorrow with our new intake, thermal lid spacer, and a couple of other goodies in hopes of digging deeper!
