Actually to my knowledge the Hennesy 550's best recorded time at a track to date is 12.1s @ 120.1 MPH.
I think ARD still holds the top slot for the 2010 Camaro at this point with 11.29s @ 122.4 MPH.

Of course this is all based purely upon who's posted time slips and/or the posts that I've managed to keep up on. It's quite possible that someone slipped one by me or that there are ppl running in the 10s and just not posting.
