    Default Help with $$$$ Build

    Hi Guys, I have a small fortune into this engine already, looking for some help from guys that have experience with turbos and tuning - as per my signature, I think I've got a great start but need to reconsider my turbo option for sure. I initially bought it for my cummins 6.7 but blew the motor and have this thing sitting new in box. I cant see it working in a set of twins or compounds right? Its kind of just a mid size turbo.

    Any and all suggestions would be appreciated!

    Nobody has any suggestions, No Turbo guys out there or vendors that have experience and want to sell some parts?

    My first duramax build and obviously a new member here as I'm typically a Cummins guy - The cummins forum must be a bigger community with much more experienced enthusiasts.

    I am surprised to say the least

    My Guess is there aren't many looking for outrageous power builds.
    Most want modest gains with stock reliability.
    Contact Kennedy Diesel he would be the guy that may have some answers for you

    Do you have a compressor map for this turbocharger?

    A lot can be inferred from compressor maps, including smoke, slow/fast spooling, power range, boost pressure, exhaust backpressure, EGTs and a lot more...
