What is new and different?

To make it simple Reds Racing's new generation engines will be produced with different materials, from different suppliers and with new technologies. 

New Crankcase design: Reds Racing S line features a new and unique high stiffness crankcase design. Furthermore, we have decided to change materials and casting technology. The new engine is produced with pressure die casting while the R line crankcase with gravity casting to provide better quality.

New Carburetor: Another big improvement is the brand new aluminum carburetor made from pressure die casting. We have decided to change carburetor materials from plastic to aluminum to further improve idle stability and tuning. Furthermore, the new carburator is  30° inclined for better fluid dynamics to increase engine power. Moreover, the new carburetor has an insulator to reduce carburetor temperature and increase idle stability at high temperatures. 

New Clamping System: the new carburetor retainer allows better blocking of the carburetor without damaging the plastic bush thus guaranteeing better reliability.

New Materials: 721 Scuderia features new materials for piston, sleeve and crankcase in order to optimize thermal expansion and improve power. The idea was to develop a high power engine even more powerful than WRX and WR7 engines with exceptional fuel mileage. 

New 7 Ports Sleeve: We have decided to realize a new high torque 7 ports sleeve for improved torque and power output.
