My dad ran a 13.89 @ 104 on a crappy 2.20 60'. It could do 13.6X with a good launch. Only mod being U/D pulleys.
stok they are rated @ a 13.99, my best with nitto d/r's was a 12.98..... but I am in the process of getting a t-56!
I usually get 16s @103... burnouts just never gets old with me. Just a sheet of paper specifying that you have a special limited production car and a set of numbers to make you feel more special than the GT crowd. I tend to rub it in co-workers faces just because they don't have one.
