so ive made alot of passes on my car and come to know and expect some things based on what goes on in the 1/8th...
1st: my car is a sport shift auto and im in 3rd before the end of the 1/8th and remain in 3rd through the 1/4 3rd is good for 113mph +
i have over 300 passes in the 1/8th and 100 in the 1/4

2nd i average 21Msph pick up from the 1/8th to the 1/4 with an occasional 22
with some of this in mind,can i make any assumptions about my previous best runs versious new...here are some break downs

previos best 1/4 :
2.068
5.869
8.930
@79.85
11.583
1/4 13.794
@101.54

current best 1/8th
2.013
5.650
8.647
@81.53

obviously im making more power now...but i guess my question is...as power goes up does the gain in mph go up or does that remain more constant ? and if you pick up 3/10ths in the 1/8th how many 10th do you knock of on the second half...
looking for good guesses
