Sonic X.12 competition nitro engine

The new Sonic X.12 is the follow-up model of the successful V.12RS engine and designed for competition 1/10th on-road racing. The engine comes with a completely redesigned 3-port sleeve with “teardrop work” and made from a new material with less “pinch” compared to last year’s engine. Additionally the engine is equipped with a “knife edge” conrod and a balanced crankshaft with a red silicone insert to reduce inner turbulences and to optimise the fuel flow. Also new is the combustion chamber insert which has a similar design to the ones used in Sonic’s .21 engine. The X.12 is equipped with Swiss ball bearings, an ultra lightweight cooling head and a composite valve carburettor with a 5.4mm aluminium venturi. The Factory Tuned engines additionally feature a fuel flow optimised back plate, and a hand-optimised crankshaft and sleeve.
