Balance of performance (BoP) has often been a taboo discussion in sportscar racing because everyone wants to find an advantage over their competition and be able to use it. But new technology arriving in the paddock could make those debates a thing of the past.
Sportscar racing regulations in WEC and IMSA are unique in that, to keep racing competitive, they opt to “balance” the performance between almost a dozen different engine types for a given class. In the past, this was done through methods ranging from data collected from manufacturers to analyzing data collected by engine dyno tests. This year, IMSA aims to better equalize their Grand Touring (GT)-class cars by introduction of torque sensors for the 2025 season.
