The new Alpha engine, the Dragon IV, is a pre break-in, 3 port engine designed to the highest specification. The Dragon IV continues with the Dragon III?s benefit of being easy to tune and within 2-4 tanks, be ready to race.
\n
\nWith the new engine, we are able to improve the following items.
\n
\nThe crankcase has been redesigned to improve the efficiency of intake and exhaust, the flow of fuel from the carburetor to the combustion chamber, and this results in less losses and greater fuel efficiency, furthermore, an increase in engine power .
\n
\nCeramic bearings: Reduced friction, lower weight, improved longevity.
\n
\nThe high quality material, ceramic bearings are fitted as standard to the Dragon IV, and with less drag, more energy can be applied to the wheels. It?s reduced friction, lower weight reducing the drag, and increasing the engine power and the speedup function.
\n
\nDEC Crankshaft: Reduced engine vibration, resist wear, good lubricity.
\n
\nThe new version of DEC Crankshaft, has the Alpha Patent ? Dynamic Equilibrium, which can efficiently balance the inertial force from piston pin, from conrod, and from crankshaft rotation, to reduce the vibration of engine and to increase the engine power. The timing on the crankshaft has been altered for more power and a more linear power delivery has been achieved when combined with the new piston and liner.
\n
\nPiston/Sleeve:
\n
\nRedesign air intake can provide the fuel efficiency, more power and a more linear power been delivered.
\n
\nPiston Pin: The piston pin improves the hardness surface and the durability in order to reduce the possibility of bending, also made very light.
\n
\nCooling head: the new cooling head adds one more layer, but has been lowered for improved center of gravity in order to handling of the car, whilst keeping good natural cooling effects when positioned in car.
