    Hello everybody

    this is Mostafa from Egypt i'm a turbocharger technician and I found many interesting things on this website
    I have some inquiries about boreless compressor wheel

    1- as I noticed it is a patent for garrett so only garrett can use this also I found that it came only in the series GTA42-55
    so do you think we will see this type of compressro wheel with next new series ??

    2- does anyone can help me about reparing those turbos come with compressor wheel type , some times it comes without nut on the top there is no place to put my key and unassemble it , how should I deal such situation like this ? And how to deal with the balancing of this type if I unassemble this wheel how to make sure to reassemble with same position ?
    Also if anyone have a video or pictures for the repairing process of anyone of those models GTA42-55 please show me

    Thank you.
