It's not quite an apples to apples deal as most bolt ons wont do much, especially without tuning, and some things like throttle bodies, may actually work against you. With the exception of the Hellcat, we have speed density intakes, and they are a lot pickier than mass air flow set ups.
That said, the 6-speeds are usually in the high 13s/low 14s depending on the driver, and the autos are usually in the mid to high 13s.
The '15s with the new 8-speed auto are faster, but almost need drag radials to realize it as 1st gear is so steep. But my '15 A8 here did a 12.79 at 108-9 on a cool day, and in the summer heat it went 13.0@107-8.
A friend of mine with a 392 and A5 tranny with a tune/headers/drag radials went 13.0 I believe.
Overall it's kind of all over the place, but I would say they are very close to your basic 5.0 as far as e.t but will trap 1-2 mph slower and then a little faster than a Camaro SS.
