depends on the weather conditions...and of course slick will get you goinjg quicker, so you will trap a few miles hour faster than you ever could on street tires. I have a friend with a 16G eclipse gs-t that trapped 105 on street tires (14.4 @23 psi..race gas.....not exactly any competition for a Z) Then he got some slicks, and trapped 111 on a 12.8 second run. But I personally wouldn't put slicks on my Z because it is not a drag car, it's my daily driver, and I don't care what it will do on slicks with the passenger seat out. I just want to know what she can do on a full street setup.
