The Dragon V, is a pre broken-in, 3 port engine designed by our engineers very highest specification. The Dragon V continues with the Dragon IVs benefit of being easy to tune and within 2-4 tanks, be ready to race due to the out of the box pre broken-in advantages.
With rigorous testing of the new engine, we have been able to improve the following key items of the engine:-
Piston: The lightweight full-milled piston provides the engine power acceleration, which allows for greater torque and better fuel efficiency.
Sleeve: The hand made cylinder liner sleeve improves the scavenging and exhaust efficiency, the effect is that this further increases the engine's acceleration and provides a higher speed when compared to our previous versions, while retaining the smooth and linear throttle feel. (Note Scavenging efficiency is the ratio of the amount of fresh air compared to gas left in the cylinder after a combustion cycle)
Head Button: An O-ring is added to the new head button to ensure the engine has a lower and more constant temperature performance.
Backplate: The new backplate improves the scavenging efficiency of the engine.
Crankshaft: The crankshaft has had its timing adjusts to further suit the efficiency of the new sleeve.
Carburetor: A new 8mm bore carburetor has been developed which is easier to tune and able to provide more power depending on the venturi inserts used. 6mm, 6.5mm & 7mm Venturis are supplied with the engine. 7.5mm and 8mm as options.
Crankcase and Cooling head: New V logos have been added to the crankcase to match the new bright red cooling head.
Recommended exhaust is the Alpha 2159, and P6 plug.
