    Jeremy, it gives you no gains. All it does is make your pump stronger.
    Here are some pics of my pump with the stainless wear ring

    the stock pump has a single bearing in it. the impros mod replaces the shaft and puts double bearings in the pump.

    Bearing=roulement
    wear ring=insert de turbine

    Le double roulement a pour effet de repartir la charge sur 2 roulements a billes au lieu d'un et surtout de permettre a ton arbre de turbine de rester parfaitement dans l'axe.
    Effectivement un seul roulement d'origine ne maintient pas assez l'arbre et lui permet de se desaligner sous fortes charges, et quand l'arbre bouge l'helice va frotter sur l'insert de turbine et c'est pas bon...

    Si tu as d'autres questions n'hesite pas.

    Yeah Mike but Google translation doesn't work too well, even worse on technical discussions.

    "The double bearing causes to set out again the load on 2 bearings ball instead of one and especially to allow has your turbine shaft to remain perfectly in the axis.
    Indeed only one bearing of origin does not maintain enough the tree and desaligner under strong loads allows him, and when the tree moves the propeller will rub on the insert of turbine and it is not good..."

    Makes me sound totally retarded.

    BTW the word for shaft and tree is the same in french.
