F1 teams did/do a lot of sound analysis of the competition. Especially a few years back, when engine revs and development was free. By doing sound analysis of the opponents engine they could get very good approximations on the HP of the other engines on the grid (max rpm, rate of frequency change (acceleration) etc.).
Based on sound analysis there was even articles in F1 magazines on which of the different engine manufacturers reached what max rpm and how much power they had.
