Obviously for every second you take off your 0-60mph time, you take it off your 1/4 mile time. However as a general rule of thumb, for every 0.1 seconds you take off your 60' time, you take off 0.2 seconds off the quarter mile time....
So if this is the case, if shiv hit a 1.9, his time would be 12.6 sec @ 111mph. With slicks, 1.7 trap is doable so the car should run low 12's with a good driver.
Here are some examples of some M3's with the same trap speeds and how the times differ vs. 60'
1/4mi time 60' (both trap 109mph)
12.980 1.954
12.770 1.808
13.313 2.036 (both trap 105mph)
12.976 1.876
12.430 2.174 (Supercharged M3's trapping 118 and 117mph respectively)
12.199 1.857
