The all new Sonic V.21T 3,5ccm on-road engine is produced according to the latest experiences gathered by some of the world's best drivers. All components have been made from the finest materials to ensure high durability and reliability.

Equipped with a 7+2 ports 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, 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 modern composite valve carburettor and two aluminium venturis (8mm + 9mm) complete this new high competition engine.
