Characteristics Professional racing fuel Street 100
Street 100 gasoline is a high-octane fuel (100 units by the research method, RON 100), designed for civilian and sports vehicles that require fuel with increased knock resistance. It is suitable for engines tuned for high compression ratios or operating in forced modes.
🚗 Where can Street 100 gasoline be used?
Factory sports cars
🔹 Examples: Audi RS, BMW M-series, Mercedes-AMG, Porsche 911, Toyota GR
🔹 Compression ratio: 11.0 – 12.5
🔹 Why: these cars have high-performance engines, often turbocharged, which require stable fuel under aggressive driving
to prevent knocking.
Tuned civilian cars
🔹 Examples: Volkswagen Golf GTI (Stage 2), Lada with modified engines, VAG group tuned for 100 octane
🔹 Compression ratio: 10.5 – 12.5 (depending on modifications)
🔹 Why: to increase power, performance camshafts, ignition, and boost adjustments are often installed—all of which
require stable fuel like Street 100.
Naturally aspirated engines with high compression ratios
🔹 Examples: Honda K20/K24, Mazda Skyactiv, Toyota 2ZZ-GE
🔹 Compression ratio: 11.5 – 13.0
🔹 Why: such engines under aggressive driving require high-octane fuel to avoid knocking and maximize performance.
Turbocharged cars tuned for high boost
🔹 Examples: Subaru WRX STI, Mitsubishi Lancer Evo, BMW N54/N55 Stage 2+
🔹 Compression ratio: 9.5 – 10.5 (low for turbo engines but requires good fuel due to high boost)
🔹 Why: increasing turbo pressure raises the risk of knocking, and Street 100 allows for safely higher boost levels.
Hybrid and flex-fuel vehicles adapted for high-octane fuel
🔹 Examples: modified FlexFuel cars, tuned Toyota Prius for efficiency
🔹 Compression ratio: 12.0 – 13.5
🔹 Why: high-octane gasoline is efficient at high compression ratios, typical for hybrid internal combustion engines.
⚙️ What compression ratio is needed for Street 100?
- Minimally effective: from 10.5:1
- Optimal: 11.5 – 13.5:1
- Turbo engines: even with lower compression (9.5–10.5:1) can benefit from Street 100 due to aggressive boost tuning.
🛠 What is required to switch to Street 100?
- ECU remapping (optimizing ignition timing and fuel delivery)
- Possible fuel pump/injector upgrades if planning performance enhancements
- Knock monitoring and adjustments via knock sensors
