Between 13.2 and 13.8 depending on the driver, air temp, humidity, elevation, traction...... To many variables. My car is between .2 and .3 tenths slower in bad air. If you do have 2.73's they may actually help you by not spinning as much, thus better et's at the track. I just took my buddies stock z28 2.73 down the track and ran 13.6 spinning lighter out of the hole in bad air. If I had heated up the tires a little I may have dead hooked. I am sure 13.3-13.4 is obtainable in good air.
