2 min.read

Our Audi S4 / S5 B9 solution is a 600 HP setup calibrated for 98 RON petrol. It combines an upgraded turbo and intercooler with 4 bar MAP sensors and higher-capacity high-pressure pump components. Our S5 has used this specification for several years, including Lithuanian drag championship competition.

Our Audi S5 B9: 600 HP and championship results

Our Audi S5 B9 uses the 600 HP setup and has competed in the Lithuanian drag championship, demonstrating our S4 / S5 B9 solution on track.

The car won the Lithuanian drag championship’s Super Street class in 2024 and 2025, and finished second in 2026.

Startline Audi S5 B9 · 600 HP · Super Street: first in 2024 and 2025, second in 2026.

What the 600 HP setup requires

We fit an upgraded turbo and more effective intercooler, use 4 bar MAP sensors and improve high-pressure fuel delivery with higher-capacity pump components.

The hardware is matched with ECU and TCU calibration for 98 RON petrol, creating a 600 HP solution for uses ranging from daily driving to track starts.

Several seasons with the same setup

Our S5 provides a long-term test in real conditions. It has used the 600 HP setup for years, with championship starts testing repeated high loads.

The 2024 and 2025 first places and 2026 second place in the Lithuanian Super Street championship were achieved by this car with its 600 HP setup.

For maximum output — up to 750 HP on E85

The same mechanical configuration has potential for up to 750 HP on E85 with suitable calibration, for customers seeking its maximum output reserve.

98 RON petrol and E85 settings can be integrated into switchable maps selected using a steering-wheel stalk. The selected map must match the fuel in the tank.
