100 octane vs 93 octane

Any real performance gain (if tuned for 100)? Doing some 1/2 mile racing tomorrow (it's supposed to be damn hot tomorrow too) and debating if it's worth it, considering I'd have to burn 1/2 a tank of race gas just to get there (nobody sells it around the race area, so I'd have to fill up by me and drive down with it).
