    Impeller gurus?

    Attachment 320630Attachment 320631Attachment 320632Attachment 320633

    I've been told Yamaha guys have been doing this for years from GP days...

    I've been given this impeller for a turbo kit, the hub of the impeller is oversized and has a decent gap with the impeller housing... There is about a 5mm drop off in the water path.

    Whats the advantages/disadvantages of going from a 83mm hub down to a 73mm impeller housing hub in "step"?

    It's a common trick to run a larger 83mm hub impeller on a small hub pump

    Thanks Jerry.

    Your customer was asking me why and I didn't have the answers!
