Cant wait to hear George, any idea of the volume of the airbox and the runner length. Been learning alot of theory around air flow and helmholtz resonance just wondered what rev range the runners are designed to produce peak power.
Have read that in theory the airbox should be between 1.5-2x the displacement of the engine, be interested to see how this works in practice.
