Default 91 to 93 octane

how much of a difference do you think 91 to 93 octane would make on a quarter mile run with my cam only tuned car? accidentally ran last week with 91, going back tomorrow with 93. if its even .05 of a difference, thatd be cool.
might not be a difference at all.

I doubt it would make any difference at all. But give it a shot, just remember the variables of two different days.... ie, weather, temps, track condition, etc, etc. Makes it very hard to do a comparison.

You won't make any more power with 93 than 91 unless you were getting spark knock with the 91 (doubtful).
