    Use impeller nose cone. YES OR NO?

    what are the benefits of not running the nose cone on the dynafly impellers in the 06 GPR pumps?
    ive read where some people with really fast gprs are not running a nose cone,WHY?
    would this not cause cavitation?

    I am not using a nose cone.... can't tell you if there is gain or no gain. I just don't use one.

    I don't use one either. Had one to start out, took it off to see if there was a difference. I couldn't tell so I left it off.

    Matter of fact I even know of a tuner, no names mentioned that used to leave the prop tool on the shaft all the time. And it is not WFO.. I am not kidding in the least bit either...
