sorry mate don't know what your saying ,you wouid't run one with no water but the guy running no water on his bb turbo it must be the problem, not oil ,i would never use a restrictor only if the turbo smoked may be, but they restricted standard and don't need restricting any more not unless there is a problem ,i have enought cages here thats blued the cage and melted ball not enought oil cooling to the balls
