    SC Nut Cone

    I saw somewhere someone posting a cone that covered the nut on a turbo impeller. Why hasn't anybody come up with this for our SC impellers?

    Seems to me that it would help direct the air flow to the impeller blades. Would it not improve air flow? Boost? Seems easy enough to prove. Someone build one on a lathe or CNC machine and test it on the boost guage.

    Looks like it would have to be a press fit. If it has two small holes on opposing sides, you could use a small slide hammer with pins to pull it back off when needed.

    Anyone in the know on this? Would this benefit our SCs?

    I do not see why it would come loose, a nut is a nut.

    As long as there are the same amount of threads and it has the same torque I would run it.

    One thing to remember is that the weight of the spinning mass will go up.

    Most people are trying to get the weight down so it would have to make a difference in airflow to counteract the effects of the added weight.

    Just my .02

    NC, that is the picture I was refering to.

    I was refering to a design that could be press fit in the SC just over the stock nut. As long as it was secured and didn't come lose.

    As I said, if you press fit it in, it should be tight enough that it will not losen up. To get it off, you would have to use some sort of slide hammer with prongs that would fit into the sides. Tapping it in should not be too difficult. Press fit is easier and cheaper to make too.

    Who has the equipment to make these for a decent price?

    i wouldnt trust that if it was just press fitted. it would be much safer to simply drill and tap the bottom. i would like to try one...
