bq97 that makes sense! Everthing I have read says if the manifold and runners are smaller in volume that will increase air velocity and low speed power. If we open the runners up, we gain top end power, if the engine can turn fast enough to use the added air. On our 2-cycle go-kart race motors we open everything up to the max allowed, but we turn 14,000 to 15,000rpm!
OK, if we follow this thought, the insert I have should be better for low end power! Its mass is larger which equals less manifold volume.
Any thoughts?

Hey if we make a rotating insert, hooked up to an electric DC servo motor, computer controlled..........variable intake volume
