Adding a Velocity Stack
thought I'd give this a shot. I would like to put a velocity stack on a
Mikuni HSR45 carb. It will be inside a K&N round tapered air filter,
the end of which is flat. How much space should there be between the
mouth of the stack and the inside of the end of the filter in order for it
to function properly? The stack is not so much for tract length tuning as
it is for straightening the airflow and reducing turbulence at the
entrance to the venturi.
