any idea what an 8.78 at 81mph in the 1/8 mile . . . would equate to, in the 1/4 mile? 60' times were 2.01 to 2.10 300' (?i guess?) were 5.0-5.1ish performance Mods: 07 GT, 5 speed, 315/35 17" NITTO' 555R extremes at 20 psi. 3.55:1 gears U&LCAs, Dspec shocks (nearly full-soft front / full-hard rear) panhard rod, swaybarS. C&L CAI, 3" manifold-back exhaust, 93 octane VMP tune, CMCV deletes, and 25%UDP's. density altitude = 1772 launching around 3000 rpm, with some spin,, and a small 2nd gear scratch doc
Here is my run back at the end of April this year.(#42) Here is my run from just a few weeks ago(only thing different than April runs was I dropped 195 lbs in car weight). All runs were done with the mods in my sig and stock 235/50-18s@33 psi.
2 weeks ago was my first time at the track. Best run of the night was 13.518 1/4. For the 1/8 I ran 8.771@81.86MPH, so very close to you. My guess would be if you were running the quarter, you'd have been at 13.5. It's hard to tell, though, because there's a lot that can happen in that extra 1/8 mile.
