How a 1mm error had Supercars champ driving a slower car all season
Supercars and Triple Eight Race Engineering have both responded after the revelation that 2024 champion Will Brown has been driving with an engine airflow restrictor that is 1 millimetre undersized all season.
During the 2026 Supercars season, Red Bull Triple Eight Race Engineering driver Will Brown unknowingly drove a Ford Mustang with an undersized airflow restrictor, causing his car to be 0.15 seconds per lap slower than the competition. This issue was discovered on Tuesday night after a poor performance in Perth, leading to Red Bull Triple Eight Race Engineering and Supercars apologizing for the oversight.
Brown's car was running with an engine airflow restrictor that was 1 millimetre too small, which had a significant negative impact on the car's performance. The undersized restrictor was supplied by Supercars and was intended for demonstration purposes only, but it was mistakenly used throughout the entire season. Supercars acknowledged the mistake and is now reviewing its technical and operational procedures to prevent similar incidents in the future.
Brown will now compete with parity against other Mustang drivers at the upcoming Queensland Raceway event on August 21-23.
