147 In the J30. Took forever to get from 140-147, not enough power to over come my crappy aerodynamics. < That was before lowering! Dunno if lowering helps it any, and Im not going to test since I have a bad ticket in my past and try not to do insane speeds anymore.

Also have been somewhere around 168 in my friends 300zx TT. Have vid but he opt'ed me to not post it anywhere.
