Data compilation courtesy of mtxeclipse. The basic idea here is to compare the time it takes you to accelerate from 70-90mph to others and their 1/4 mile ET and MPH to get some rough idea what you might expect to be running.
|12.7||108||2.76||shifing at 7k in 2nd|
|11.9||116||2.57||shifted 2nd over 8k|
Notes: Sample data is 1g data. Assumed AWD. It seems that taking 2nd over 8k puts 70mph inside the shift point
