        What is needed to fully utilize an Twin-port Turbine housing?

          You can't really setup a header effectively on a 5 cylinder to take advantage of it IMO. What I'm doing is rounding the divided housing out so air has a smoother path into the turbo.

            Aha, would it not work if i was sending 3 cylinder to one side and 2 to the other or is it better to have all the gasses go to the collector and then again divided in 2 ?

              Do it like Justin described, another nice advantake to the evencylinder engines.

                if 2 and a half cylinder will go to the one side and 2 and a half to the other it would not be fine isnt it??

                Got the Turbo today! Very nice HX40! it has a ca. 120 intake outer diameter!

                The other one he had, had ca. 100 mm outer intake diameter! The wheel and the hotsides look almost the same! I think the turbo has only worked some hours, it is in an allmost new state! It is empty of oil and i think the small play the shaft has is normal!

                I have also read in some other forum that the garrets even the Ball bearing ones have some play when new!

                  I have stroker with HX40, 1,2bar comes from 3200rpm till 6500rpm, engine was only 400km after build so no more pressure was rised, this summer will try to boost ~1,8bar.
                  it was 405hp & 540Nm

                  p.s. stock EM

                    What kind of turbine housing do you use?

                    i think 3200 and 1,2 bar is very nice!

                          I don't care what's the limit, it's enough for me. k26 is stock audi 200

                              nice nervas, thanks!

                              Doesnt all the HX40 have the Map Width Enhancement groove?

                              Just out of curiosity how much must the clearnce be between the Turbine housing and the Turbine wheel? How much shaftplay is good for an almost new turbo without oil?

                              What of hose fitting should i use here ??

                              This is the intake of mine


                              This is the Compressor outlet


                              This is the other one he sold! Is has a small bump on the outer ring witch something easy repairable! A Friend wants it for a smaller displacement Drag car! I told him it is going to be very big and now he is considering about fitting it!

                              Here the other type of inlet
