no no no ... its not like that ,or at least so simple, it is the Altitude compensation unit, and type of element that makes the diff.
A N/A 601 takes 35 to 38cc at 1013HPa, the turbo version 42 to 45 at 0,12MPa, but the turbo is with 6mm elements....
so is not so simple , most pumps handle 5 or 6 turns , some don´t some elements have leak off Groove some don´t... u can´t just say it handles more turns cause is N/A or Turbo.
6mm element from 601 turbo engine gives 75 to 80cc max, has leak off Groove , if u ask full rack from governor it runs bad...
521 element is 5.5 comes in most 601 2.2 N/A gives 65cc and has no leak off so no problema giving max rack travel ...
u see is a tricky thing, thats why most people do not suceed tuning pumps by their own.
