The car in the other lane is probably close to a "best case" scenario. His 60' is REALLY good for the ET. You could get your car down to the low 1.5's or high 1.4's without too much trouble...that should get you into the high 10's.
What is your tire size and gear?
67 Barracuda street car, 408, e85, 1.38 60', 6.44 @105.9 in the 1/8 mile, 10.19 @130.5 in the 1/4...so far....
