some1 plz change 1/8 to 1/4 time

hey guys,

I went to a 1/8th mile track yesterday and ran, I didn’t do anything special but take out the spare, (I keep my tire pressure at stcok), and I didn’t advance my timing, my step dad also came along and raced me each time (he drives a 95 300zx Convertible, auto), I bet him every time but once, his best time was a 10.08 tho. mine are as following:

R/T = .736
60’ = 2.498
330 = 6.681
MPH = 54.44
1/8 = 10.171
MPH = 69.24

 Would anybody happen to know what the time would be in a quarter mile? This was my first time to a track, and I got no damn traction at all, in first and second.... I got to run like 40 times, I was the only one running for about 1 hour, so I tested things and times.  I was gonna spray, but umm I was poor and couldn't afford to fill the bottle, not to mention is was cold as hell outside, and I didn't have 1000psi, and so I don't have a bottle warmer, its no bueno, but thats besides the point, anybody help? thanks...

from the caculator i have its a 15.8. most likely off a little since i got it from a stang site. :stuck_out_tongue: j/k but seriously i bet its based on RWD at that.
