I believe with a 1.6 60' time (not hard IMHO) you can hit a 10.99 with 550rwhp/550rwtq. Brad's car has done 11.2 with 460 rwhp/500 rwtq. It should knock another .1 off of the time with the new clutch, he ran the 11.2 on a slipping clutch.
Despite what everyone thinks, it does not take 700+ rwhp to run a 10 sec time, maybe a low 10, but not needed for a high 10.
