Sonic Nitro Engines V.21T On-Road


In a few days, Sonic Nitro Engines will release the all new Sonic V.21T 3.5cc on-road engine that has been manufactured by Picco Micromotori. The engine has been developed with the help of some of the World’s best drivers and the components have been made from the finest materials to ensure high durability and reliability. Equipped with a 7+2 port sleeve with “teardrop work” and a CNC machined flat piston, the engine provides great power over the entire RPM range while having a very efficient fuel consumption. The 14mm turbo crankshaft is equipped with two high density weights to improve the overall balancing and filled with a silicone insert to reduce the inertia and improve the fuel flow. The special backplate plate, the optimised crankcase and the “knife edged” aerodynamic con-rod help even more to reduce turbulence inside the engine. A special turbo combustion chamber with a cooling fin and the super lightweight 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 and two aluminium Venturis (8mm and 9mm) complete this new high competition engine.
