Sonic V.21b Off-Road Engine

Sonic Nitro Engines is proud to release details on the Sonic V.21B 3,5ccm buggy engine. All components have been made from the finest materials to ensure high durability and reliability. Equipped with a 5 ports sleeve and a CNC machined flat piston the engine provides great power over the entire RPM range while having a very efficient fuel consumption which can be crucial in the finals. The 14mm turbo crankshaft is filled with a silicone insert to reduce the inertia and improve the fuel flow.

The optimized crankcase and the the “knife edged” aerodynamic connecting rod help even more to reduce turbulences 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 temperatur at a moderate level. High quality Swiss ball bearings, a dust protected front bearing, a modern composite valve carburettor and a 5,4mm aluminium venturi complete this new high competition engine. All three types of engines are now in delivery, information about the distribution network can be found on the homepage in a short time.
