Took the wife's Focus out to the track on Saturday. Bout 3800 miles on her. Running 87 octane, tank half full. Temps were in the 40's-50's, and the DA was probably 700 or so by the end of the night (started around 1700).
Breakdown of the times (all runs done with TCS off, S mode, brake standing at the line):
16.40 @ 85.34
16.53 @ 84.76
16.32 @ 85.88 (as seen below)
reset battery to possibly clear any knock from running 87
16.08 @ 86.69
16.12 @ 86.62
16.13 @ 86.07 (as seen below)
16.46 @ 84.83
If i do it again, i'll definitely run premium to see how it acts. I feel with minor weight removal, premium gas, good air density, it's a high 15 car.
