In my testing I found that getting some fair amount of wheel spin at launch resulted in higher trap speeds but poorer 0-60 ft and 0-60 mph (but not by much) times. Apparently you lose time to those marks but end up accelerating faster, later. I used to abort runs with lots of wheel spin but once I noticed on the one or two I kept doing that I got these more impressive 1/3 speed numbers I started finishing more of those runs to check my initial findings. I have a STEP so usually have less variability than I would have in my older (geezer here) manual tranny days. My best 0-60 times usually end up with a 1/4 trap speed of 103-105 but those with high wheel spin and lower 0-60ft times I have had as high as 111-112 mph - not saying my 6er is all that mighty just trying to give my .02 on why trap speeds might be higher in some cases
