By my rough calculations, I read an AWD GS as weighing 3980lbs. Those ET/MPH combos rank it between 270 and 285 wheel horsepower.
My spreadsheet says that your ET could have been 13.91 with everything perfect so that looks like you did quite well.
Next time, run with 1/2 a tank of gas and no spare tire/anything else you can dump. 100lbs is 0.10 second.

That was half a tank, but still had spare tire, and 50+ lbs of tools and other stuff.
My next time out I will cut excess weight, less fuel, and focus more on my driving
ALSO
I found the engine to heat soak badly with the engine cover on, so that was removed and hood opened to cool before runs 3 and 4. Monitoring trans, coolant, intake temps from OBD2 bluetooth

An old racer trick was to put bags of ice on the intake. I haven't looked to see if our cars have the heated plenum/throttle body. Blocking that off will let cooler air in. For bonus points, connect up a cool can and circulate ice water through it.

I would look for a way to override the radiator fans and let it cool down in the pits between runs.
