74 mm compressor, did You really mean that?
IMO that size compressor is for some 1000HP?
Also 65/74 turbine/compressor ratio sounds hmm...
( maybe for a diesel generator with constant rpm )

Biggest T-4 I have heard had some 60 compressor.

Regards
Jukka

  <<Thanks Javad

  I think we agree: Allmost anything is better than oe turbo EM :)
  Those guys want to make some kind of tube header with modified
  K-26. I´ll let You know how was it and what happened. >>



  Yes, overall, but I still hold that if your goal is 250hp or less, no reason to mess with the stock manifold, overall its a good design within' that range, very good in the stock application.


    <<One more thing: Your A/R seems to be "light" as mine too, but
    Your compressor is quite big, if we think OE K-26 has 42 mm
    and Your T-3 has 57 mm wheel. How about turbine side, the 3rd
    stage hot side tells me nothing, because I´m not familiar with
    Garretts?>>



  57 trim, not mm, the major diameter of my compressor wheel is 2.95" or about 74mm, the exh. turbine major is 2.559" or about 65mm

  << I mean what is turbine dia? If we think the ratio, it must

    be something like 65 mm and that means You are looking for
    450-500 Hp?>>



  Well, I'm looking for about 3-400hp, I don't know if 500 is realistic for a 10v on the street, even 400 is really pushing it.  Currently I'm running about 14psi, I estimate (gtech pro) about 275-300hp flywheel on 91 octane, anymore boost kindof pushes the ignition curves, plus, I can barely accelerate on the street without killing someone or going to jail, not much acceleration with other people around.

  Next month I will be at the track, however, and I'd like to try as much as 20psi with 100 octane, should be interesting.


    <<ps.
    I would love to have a ride in Your car and would like to give You
    a ride

  Likewise, fast Audi's are fun, I'm always open to giving rides to listers (assuming them come to my house and country  ;)
