    Bored out pump?

    JasonZE I think mentioned this in a thread ... bore out the SS pump liner and have the impeller edge built up to match. Anybody have any news at all on actually doing this and the results? As HP goes up, a larger pump can be better at turning that into thrust, all else being equal ...

    I will have to check the specs but it is only for hook up on the start line and this stage in theory only as we have never run one like it.
    Hope to be running in the next few weeks so will let you know.

    Thanks Jason, keep us posted on the results ...

    Kenny, did you just bore the liner and leave the diameter of the pump (vane area) the same, or did you bore that out as well? Did Skat make you a special prop to fit it?
