IMO the only reason a turbo'd car has not broken 12's is driver related. They have more then enough power to get into the 12's.
For that matter look at the S/C cars. I do not even recall one that's even broken into the 13's. That's ranging from 260 to nearly 400 wheel HP in those cars as well. They should be well into the 13's. One of them perhaps even cracking 12's.
The bulk of the ET on this platform is made in the first 330' and that is all driver vs traction. A tenth or two can be made from smooth, fast shifting as well. That's NOT powershifting!
Well that's all taking for granted one doesn't shell an axle...
