No, you are correct. Torque is essentially a function of displacement (forced induction increases effective displacement). An 18,000 RPM 3L F1 motor will not make appreciably more torque than a 8000 RPM 3L I6 or V6 is a passenger car. In fact, most every engine (naturally aspirated, that is) on the market will make between 70lb-ft and 85lb-ft per liter of displacement. Go ahead and look up any car from Kia to Ferrari and you will see this to be true. Even if you look at racing engines, you will not see anything over 100lb-ft per liter.
