Characteristics Professional Racing Fuel Racing Pro 123
Usage of 123-Octane Gasoline (RON)
Gasoline with an octane rating of 123 (RON) is an ultra-high-performance fuel exclusively used in specialized applications requiring:
- Maximum knock resistance
- Extreme compression ratios
- Short-term peak loads
- High thermal stability
Primary Applications
🔹 Professional Drag Racing (Top Fuel and alternative classes)
- Nitromethane-based fuel blends (typically 70-90% nitromethane + 10-30% high-octane gasoline)
- Experimental fuel formulations for record-breaking runs
Examples:
- Top Fuel dragsters (8,000+ HP)
- Supercharged Funny Cars (5+ bar boost)
🔹 Land Speed Record Vehicles
- Vehicles targeting absolute speed records
- Hybrid-engine special builds
Examples:
- Bloodhound SSC (project)
- Turbine-powered vehicles like ThrustSSC
🔹 Experimental Racing Engines
- Engines with extreme compression ratios
- Gasoline-alcohol hybrid blends
