I was using a correction factor based on 1.60 60ft time, I’ve logged/tracked that every .01 second I shave off in 60ft’s at the same track day, I drop .065 and used my ricer math from there to figure he could have ran an 11.1x 1/4mile time yesterday and plugged it into the calculator lol.
I also find that the N/A field in that calculator is more accurate because I sometimes get a positive correction factor (showing that I would actually slow down in lower D/A’s) when I view the supercharged/turbocharged field.
I’ll correct your time, I want to add a note column because of your upshift issues, but will just keep it simple for now.
here is the breakdown of his slip
60’ 1.649
330’ 4.876
1/8 7.456
MPH 93.96
1000’ 9.643
1/4 11.395
MPH 125.76
He gained 31mph in the back half! that is some crazy stuff! On his 122.56mph trap on straight 91 octane, his 1/8mile trap was 96.xxmph, so the higher D/A definitely affected his 1/8mile trap for sure.
