Does anyone have experience with how much adjustment is needed to start effecting ET? So, today I got some testing done and either I have a issue with the car or I need to adjust T-stop out more to start effecting things... Overview of today: Basically, I made six 1/4 mile runs today between 1pm and 4pm. Three runs were all out (T-stop not hitting carb linkage) and three runs with T-stop adjusted out 5-6 complete turns out after initially touching carb linkage. The problem was the runs at full throttle were SLOWER than when I had T-stop adjusted out 5-6 turns.. Make no sense to me...! LOL
tt3 5 turns out 1.774 12.618/107.45
tt4 0 turns out 1.785 12.682/106.97
tt5 0 turns out 1.782 12.583/107.61
tt6 5 turns out 1.763 12.570/107.43
tt7 0 turns out 1.775 12.601/107.25
tt8 6 turns out 1.770 12.555/107.90

*Carb is a Holley 700 DP. (secondary linkage removed, so just running on 2 barrels)...

Thanks!
