Novarossi 35 Plus 21 9 Port Rally Race Engine New
This is a new Novarossi 35 Plus 21 Rally. Is new a cooling head, piston and liner, carburetor and R4 conrod.
Its crankshaft is diameter 14,50mm. Its sleeve is endowed with 9 ports and the piston made with an alloy of aluminum-silicon.
The sleeve with 9 ports was selected to best performance and quality without other concession.
The Novarossi 35 Plus 21 is endowed with high-speed main bearing.
This engine is intended for the 1/8 Rally - GT car.
Crankcase in the 35 Plus 21, have been updated and made more rigidity and improved internal fluid dynamics.
The cooling heads of the 35 Plus 21 engines are made lighter by making aditional holes in the cooling fins.
This reduces the overall mass of the engine..
This piston is "microcasted", a technology developed by NOVAROSSI, which is a perfect mix of low-weight and high strength with good resistance against high tempratures..
9 Ports ABC Piston Sleeve
The sleeve has 9 transfer ports and an exhaust with booster ports.
The special shape and positioning of the ports, covered by a patent, improve the internal fluid-dynamics to obtain the maximum possible performance.
The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase.
The balancing is done by two inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration.
The ball bearing was lowered to 5mm.
The front part was extended to improve the seal against fuel leaking.
High Speed Rear ball bearing:
The rear ball bearing has high quality steel balls to minimize wear and inertia to improve acceleration and fuel consumption.
The rear cover presents a round shape to optimize the filling and reducing the dead spaces.
the steel plate is to reduce friction and to expand the lifespan of the conrod.
