Sonic 2021 PS.12 PSS engine

Sonic Nitro Engines have released the updated PS.12S 2,11ccm engine. The 2021 variant sports a new crankcase which is made by die-casting to avoid blowholes as well as an updated cooling head, piston-sleeve set and crankshaft to fit the new crankcase. As the engine is used as the mandatory engine at various events across Europe, like the McBest Cup in Switzerland or the Pro Stock Series and Nitro West Masters in Germany, they have kept the price at a very competitive level to attract beginners and amateur racers. The first batch is already sold out but the next batch is available very soon.
