Reds WR7 Diamond 3.5cc nitro off-road engine

Italian company Reds Racing have introduced their new WR7 Diamond 3.5cc nitro off-road engine. Based off of the popular R7 World Edition engine, the new power plant is of a high-torque design and it features a DLC-coated crankshaft and backplate for reduced internal friction and improved durability while utilising a redesigned crankcase, cooling head and combustion camber insert to further improve performance and durability. Of a high-power 7-port design the power plant features an exhaust port with boosters to improve mileage and to provide a smooth yet powerful power delivery. Part of the engine package are also the renown HCX carburettor with Gen 2 venturi insert, anew lightweight and low centre of gravity cooling head and each engine comes with a hand-tuned, silicone-filled, balanced and tuned crankshaft, a work that is carried out by Reds’ own M. Rossi. The engine is available separately, pre-broken-in by M. Rossi, as Elliott Boots Race Ready edition, including the Reds 2143+S exhaust or as all-out combo package including the 2143+S exhaust and Reds’s own Quattro clutch.
