Yesterday I hit the 1/8 mile drag strip again. This time, I couldn't go lower than 11.27 (.88 reaction time) vs 10.7X last time. Here's the thing, last time I went to the drag strip I ran without the big-o-wing I have, without the 4 hella lights, no emergency tire, no jack, no nothing on the back (the rear seat stayed there), no tool bag (at least 25 pounds), 15" steelies all around, and myself was approx. 10 pounds less. My best time then was 10.7X with a reaction time of .67X Yesterday, I ran with all the extra lugage (wing, lights, tool bag, electric impact, extra tire, etc), plus the 17" EAP SVT wheels all around. Last time I ran with 91 octane gas (1/4 of tank) and a NOS octane booster. This time I only used 91 octane (1/2 tank). Besides weight, the only difference from this run to the last is that then I had NGKs Laser Iridum spark plugs and the Octane Booster, and yesterday I had E3 spark plugs, no octane booster, CFM udps and MSD cops. So, either my car got slower or weight really plays an important factor. What do you guys think?
