Many years back, a friend worked at a car tuners.
They regularly dealt with the popular Sierra Cossies, Escorts, Celica GT-4s, etc. etc. They even modded the bosses brothers Bentley.
Friend put his car on it - 82/83 model Ford Sierra 2.0 Ghia Auto. We had always thought it felt chronically underpowered. Rated out of the box at 100brake.
Actual power? Just under 50. It ran like a total dog.
