    Thanks a ton for your video! Super informative! I am now picking between pair of 7163s, 7670s or 8370s (bigger brother of 7670) for my 2018 F90 M5 (4.4l v8 - each turbo paired w. 2.2l 4 pot). Target is 1200crank and it’s a daily so I’m leaning towards 7163s w. 0.85 A/R v band as there will be sizable difference in spool/transient response between the 7163 and it’s bigger brothers right? Do you agree or would you recommend something else?
    And - 2nd part of the question - on 7163s I planned to go with external 38mm tial gates (0.85 A/R v band style) as opposed to internally gated same 0.85 A/R v band. In your video when talking on 7670 you recommended internal over external gate. Would you still recommend internal gate on 7163? And why? Thanks a ton!!!!! Subbed for more

    On the 7163 turbo , what RPM range would you start to see the difference in torque between the T4 .8 vs the V band .85 , thanks for your advice #newB,
    Also can you show compressor maps for these two
    Your explanations are very informative and clear especially for those of us who are now learning , certainly feel lots less lost when I watch your vids, absolutely great stuff 🙏🙏🙏

    Awesome explanations of the compressor map and differences between the the two types of housings for the 7163, I had read in one of the comments section from another video of yours that you could offer a different compressor for the 7163 to take it all the way to 650hp capable. A video on this would be very interesting, especially if not much response is lost in the process. Also I was wondering how you could get the benefits of using the larger a/r 7163 on an engine other than the EA888, I understand the your swirl adapter plays a large part in increasing the response of the turbo with the larger .85 a/r compared to the twin scroll .80.

      Ryan we do offer larger wheel BUT IT MUST be used together with the AR85 turbine housing with the lower backpressure in order to make the higher power. its simply a larger inducer(up from 57mm to 59mm) and exducer (up from 71mm to 76mm)

    • @TurboDirectSA
      @TurboDirectSA  2 роки тому +2

      Something is wrong - the turbo will not smoke on its own. The drain must either be blocked, and/or not directed downward for gravity to drain the oil, or the ID is too small, or you have blow by in the cylinders, or the oil level is too high, or a breather is blocked. If you seeing oil "pulling" through the air filter intake, then the filter could be too restrictive..... Start with these common areas and work your way through.

      The EFR7163 has produced 550WHEEL HP on our dyno on an EA888.3 - it is rated to 54lb/min. We have seen these results in person on a handful of dynamometers around the country.
      The EFR7670 will produce the goods - wait and see, an install is coming up soon.
