The paper compares 3.0 liter F1 engines having different architectures and developed in compliance with the 1998 FIA Technical Regulations. Similarity rules and non dimensional parameters from previous projects define key geometric and operating parameters for V10 and V12 engines having equal degree of sophistication. The paper presents computed classical engine outputs versus engine speed, including brake, indicated and friction values. The V12 solution shows clear advantages in terms of pure engine performances.
