Victosport VSR03 3.5cc nitro on-road engine
World Champion Products have introduced their new Victosport VSR03 3.5cc nitro on-road engine. Compared to the VSR02 the VSR03 has a different crankshaft timing, closing 5 degree earlier, which improves low end torque and also fuel efficiency. Also some extra work was carried out on the inlet of the crankshaft to create less turbulences while on the sleeve, the shape of the exhaust ports has been changed to make maximum use of the updated crankshaft timing. The engine is available now.
