High Flow, Improved Durability, for Extreme & High Power Applications!!
Tuned engines require as much fuel mixture to enter the combustion chamber as possible. So a larger diameter design was selected to optimize flow rates. Due to the extremely high temperature conditions experienced in the combustion chamber during high power runs the durability of the valves were also addressed to improve resistance to high heat conditions. The JUN oversized valves were designed with the above factors and more so with the careful selection of materials to suit these conditions to the precision in the design and manufacturing processes to maximize the intake and exhaust flow rates will make your engine capable of big power when needed most.
JUN OVERSIZED VALVE FEATURES
HIGH FLOW DESIGN: 1mm OVERSIZED WAIST SHAPE. 1mm oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing air flow rate within the port with the reduced air flow resistance. This design with the materials used also allowed for a lighter product as well.
