It's not uncommon to see gains out of modern high performance engines when you put high octane gas in. You just arent supposed to use leaded race gas with exhaust catalysts. It will clog them up.
Unleaded 100 would have probably shown the same gains.
Guys, guys, highly oxygenated race gas is not the same as high octane gas. Highly oxygenated gas produces more power because it supplies its own oxygen molecules for combustion. This means that the same amount of air that you'd add certain amount of normal gas, you can add a ton more oxygenate gas. The more gas you can burn in a cycle, the more energy you can produce. Nitromethane is a an example of that:
Adding high octane gas alone without adjusting fueling and timing will yield no gains provided the car was not experiencing significant octane limitation before. Technically, most if not all cars should see power gains from highly oxygenated gas provided the fueling system can deliver enough fuel to achieve target AFR.
