@malex , "how can that be?" I dont think the rollout in the bad lane could be that far out of spec, but i could be wrong. That would seem to indicate a traction problem not related to your car. A little something something in the bad lane? Balled up rubber from an excessive street car burnout? You mentioned maybe scraping the track. You are foot braking aren't you? Maybe less launch rpm on the bad lap. Maybe tires with a couple lbs more pressure from a previous pass? This is where modern racers with data acquisition have an advantage (I'm not one).
Both of my local tracks (one 1/8, one 1/4) are built in the parking lot of a circle track. At the 1/8 track, the right lane has to jog left to get around it, therefore all the fast cars (yours would definitely fit that category) use the left lane. On Thursday tnt, the run them only in the left lane, usually as a single. As a result, there is sometimes a wild difference between lanes.
Just as an aside.... did you see if the incrementals matched your other passes. You mentioned a slow 60 ft and 1/4, but how about 60-330, 330-660 etc.?
And this isn't over yet because this has now become a best of 5 seeing that I've already won best of 3! We can only be mad for 10 minutes though, it's a rule. I think there's a conspiracy going on there though, setting us Mopars up against each other always.
