Dragon IV Version 2 engine
The new Alpha engine, the Dragon IV Version 2, is a pre broken-in, 3 port engine designed to the highest specifications. The Dragon IV Version 2 continues with the Dragon III’s benefit of being easy to tune and within 2-4 tanks, being ready to race.
With the new engine, we are able to improve the following items;
-The crankcase has been redesigned to improve the efficiency of intake and exhaust, the flow of fuel from the carburettor to the combustion chamber, and this results in less losses and greater fuel efficiency, furthermore, an increase in engine power .
-Ceramic bearings: Reduced friction, lower weight, improved longevity,the 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 for reducing the drag, and increasing the engine power and the speed-up function.
-DEC Crankshaft: Reduced engine vibration, resist wear, good lubricity,the new version of DEC Crankshaft, has the Alpha Patent – Dynamic Equilibrium, which can efficiently balance the inertial force from piston pin, to conrod, and to crankshaft rotation, to reduce the vibration of the engine and to increase the engine's 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.
Redesign air intake can provide fuel efficiency, more power and a more linear power being delivered.
-Piston Pin: The piston pin improves the hardness surface and the durability in order to reduce the possibility of bending, also made very light.
-Cooling head: the new cooling head adds one more layer, but has been lowered for improved centre of gravity in order to aid the handling of the car, whilst keeping good natural cooling effects when positioned in car.
