Sonic V.21LS on-road engine
Sonic Nitro Engines introduce the latest version of the successful V.21 engine. After extensive tests in cooperation with Edoardo Picco the engine features the latest long stroke ‘LS’ design offering more low and mid range power while keeping the fuel economy on a very good level. Equipped with a 7+2 sleeve with teardrop design and a lightened CNC-machined piston made of high percentage silicone alloy the engine sports a balanced lightweight 14mm turbo crankshaft with silicone insert to lower the rotating mass and reduce inner turbulences while the optimised backplate improves the fuel flow even more. A special finned turbo combustion chamber and the super light-weight cooling head ensure best heat dispersion to keep the engine temperature at a moderate level. High quality Swiss ball bearings, a modern composite valve carburettor as well as 8mm and 9mm venturi inserts make this engine ideal for competitive racers.
