For every tenth you take off your 60ft time, you normally take off 2 tenths in your end 1/4 time. You def have a mid/high 13 sec car, just need to get the 60 down, and shift quick. Launching these cars with a 5spd and turbo is just really, really difficult, and takes LOTS of practice to get good at it..Lowest 60ft I have ever pulled has been a 2.3 I've trapped at over 101 mph,so its def a high 13 sec car.
