It’s not going to be that hard to prove this. I’ll run the car on 105 octane. I expect it’ll do a 12.5-12.6 with my amateur shifting. Then I’ll take a drive in 4th gear around NorCal, run out the remaining fuel, fill her up with 91 NorCal pump, and put down the best she’s got an hour or two later. Probably a 12.9 or 13.0.
I’ll run the 93 octane program the whole time to keep that constant. Let the same ECU program decide what timing to run.
I’m not convinced if the great Sakimono of Toronto was at the strip that day with me, that his superior skill would have pulled a 12.5 out of a car, atomsphere and fuel that I could only get a 13.0 out of. The variables are prebaked.
My hypothesis is that our Audi’s are a lot more consistent car-to-car than the fuel we’re putting in. I think fuel is the most important determining factor in 1/4 mile times. Then driver. Then atmosphere. Then VIN number (variance in factory output).
Your 1/4 mile database is more like a database that grades fuel quality from various refineries around North America. I appreciate it, I just think it has little to do with the drivers (assuming they’re all intermediate-advanced competency to achieve a 99th percentile time).
I’d actually like to know if NorCal Shell, NorCal 76, NorCal Chevron, or NorCal Valero is the fastest fuel. I can probably find out by repeating this experiment.
