This master thesis, developed in Powertech Engineering Srl, is a parametric study concerning the engine-related parameters, to identify their influence on performance and acoustics. Powertech, born as a spin-off of Politecnico di Torino, is a consulting company which works in the field of 1D powertrain simulation and 3D computational fluid-dynamics. The work has been developed for Ferrari SpA, with the aim of giving them a support to find the best engine setup from both performance and sound viewpoints. GT-POWER was the software used during the whole thesis. It is included in GT-SUITE, of which Powertech is the technical representative for Italy.
