A Wheels road tester got the VT 300kw GTS into the 12's back in 2001 so I think it’s fair to say that if the conditions are right and you spend enough time with setup and get enough practice than any of the current HSV models are capable of similar times to the F6. Most, if not all the quick times posted here have come about after a lot of 'practice'. Practice that the road testers rarely get time to do. There are dozens of 'tune only' HSV's running 12's at Calder park on any given Friday night.
