Rollout vs ET

LowDeck451 said

And I’m not trying to nitpick your distance estimation, and I understand the difference tire size can make, I’m more interested in the ET difference on a 12 - 13 second car with 26ish inch tires. In post #3, he saw a tenth and a half difference, you think it’s closer to a few hundredths. Just thought it was an interesting topic.

I get it, and it is a interesting topic. How hard the car 60 fts will determine the amount of time seen from a roll'n start. The best way to see the results for a specific application is at Test n Tune (or even time trials for classes) is to go to each level of the spectrum. Shallow stage and then stage deep and compare. I always shallow stage. It's your best ET if you are test and tuning and also if you are in bracket racing you know exactly where the car is making it easier to dial in reaction time. I always leave when the 2nd yellow bulb goes off. All driver preference
