So lower specific energy, but much higher octane which allows much higher compressibility, resulting in higher numbers, and safer fuel (relatively) due to cooler charge... I always see those shows on Velocity where they find a barn car with aviation gas in it, hasn't run in 40 years, and starts up perfectly. why? Same basic principle?
