i have a 06 s197 i have diablo sport 93 tune jlt cold air throttle spacer. i have nt been to the 1/4 mile yet but my 1/8 mile time is 8.65 at 84 mph. i think thats good for mid 13s. how can i get my car in 13.0 12.9? my car is a auto
so do you have problems beating ls1 camaros with the mods you have sparta?
sparta with the mph you are running you would be well into the 12 second range. i wouldnt tell someone they dont need tires to go 13.0 just cuz you are doing it. you could probably been going 13.0 with less of the mods you have if you put a drag radial under your car and took a true advantage of the power you are making. im going 13.5 and would be into the 12s myself if i could launch my car at something more than 2000 rpm and bog it so i dont spin.
