The heads, blocks and base of the Maserati cylinder are made in the Ferrari factory in Maranello, where a special metal alloy is used to improve the mechanical characteristics of each individual component. Light alloy technology is used intensively in the production of the eight cylinders of Maserati mechanical parts and is a critical phase of the production cycle.
Thorough inspection of the metal to be used is the first step in the production cycle. It will be strictly checked to make sure it complies with strict technical standards. Once the metal has been certified, the core and shell are prepared, then the controlled cooling process begins to prevent bubbles from forming inside the melt. Any metal residue is removed and the interior of the structure is heated to be homogenized. An aging procedure will follow with a heat treatment that guarantees durable components. Finally, each element will undergo a final examination which includes some radioscopic checks of the sample.
The engines that will finally power the Maserati GranTurismo and Quattroporte are assembled exclusively by factory-trained staff at the Ferrari headquarters in Maranello, Italy. The staff training period is intended to familiarize you with assembly procedures, teach them how to work on the engine and how to diagnose problems. A certification is issued to all employees who complete the training they are ready to work on in the actual production process.
The production of the compact and light 8-cylinder Maserati 90 ° engine takes place in the engine mounting area near the assembly line of the Ferrari engines. The process begins with the preparation of one of the following subgroups: air intake manifolds, pistons, preparation of cylinder heating. Once the subgroups are completed, the finish lines assemble each component where the Maserati and Ferrari engines will alternate in the same work cycle. Each cycle is divided into short blocks (cylinder blocks and connecting rods) and long blocks (where the final assembly of the engine will occur).
The overall production system combines the advantages of the work and precision performed by the human being with the precision given by sophisticated machines. The special bolt tightening certification system sends the torque data to a central server, which will then compare the values with the rigorous parameters set by the technical office. The process will only go to the next step if the two values match exactly. Each individual engine is then checked in the test room, where the engines are set at 2,000 rpm for twenty minutes, at 4,500 rpm for the other twenty minutes and finally at 6,000 rpm for thirty minutes. The latest analysis involves checking the torque curve, peak power and final emissions. Once the last phase has been successfully completed, the engine is ready to be sent to the Maserati factory in Modena to be mounted on a car.
