    Bailer tubes

    Do you guys remove the bailer tubes in the venturi to gain more speed?
    Does it even have an effect?

    yes, we remove the saiphon tube. Its good anywhere from 25 to 50 rpms.

    I think the best thing I ever did was remove the casting flaws found in the gpr pump. Just seems to recover better and some gains in rpm also.

    The tube itself can be used as a tool, Such as if your nozzle is an 87mm and you leave the tube in it's really an 86mm If removed it's a true 87mm Now if you want to play with adjusting bigger or smaller pieces of aluminum round stock into that hole you can be amazed on how much rpm gain and loss will be achieved, Also how much speed can be gained by tuning this way
