I assumed it was just very high octane, often available at stations near race tracks. Regular (US system at sea level) is 87, premium is 93, “race” is 105-110. Could be used in dedicated race cars or ones set up to be retuned on site at the track
I ignored this excellent point. Definitely lots of folks who have street legal vehicles (or race in street legal circuits) that have to run gasoline and tune for that. Thanks for pointing it out 🙂
