Fellows,

  I have been thinking up this crazy idea of trying to make intake runner tubes out of carbon fiber. My question is regarding length of the velocity stack. Does the length make a difference? Could a velocity stack be more or less the entire length of the tube? Meaning, if I have a 12" intake tube, could the entire length of the tube be a gradual taper to the diameter of the block opening? Would that mess with the speed the air is traveling in the tube? Aerodynamics is not something I have a very good handle on, and am hoping someone out there in Fly Rotary land can shed some light.

Toughts???

BTW,  Any reasons why carbon fiber should not be used for intake tubes? May make the velocity tubes a mute point.

Thanks for any thoughts.

P.S. Any Fly Rotary fellows going to OSH??? Perhaps a lunch one day or something.
