      I would think similar to a 50 trim on a vr6, maybe a bit over 3 k for spool.

      2400rpm = 1psi 3300rpm = 20psi with 12cm hotside

      I found a user on here by the name of "G60 Scuzz." He ran a hx30 on his bone stock PG corrado and made 285whp @ 24 psi. I think 300 whp for me is no prob, considering that i'm running a 16v and I have the same holset actuator for some shenanigans

      Thats faster than the .63 50 trim my friend had on his vr6. All it could do was 10 psi at 3300 or so.

      Watching the tach, boost and road in a vrt was never easy

      what hx35 do you have 6/7/ or 8 blade compressor ?

      have you tried any other turbo on ur car to compare the differnces ?

      i read they dont come into there efficiency range till past 20psi ??

      Ive read there are different 6/7/8 blade compressors depending on year of the turbo, any specific compressor better than the other?

      All the information regarding compressor efficiency and what blade compressors are the best is all on the first page

      I think it is a 8 blade wheel. Im told that that turbo is good for much more than 15psi but I am pretty sure that I will F#** something up if I run much more than that on a stock motor.

      Holsets are efficient at over 30 psi above atm

      what happened to usrt quintin.

      Holy **** btw. There is still 10 psi left in that turbo, but i think at 35 psi the head will lift

      Hey all, I hope to be a member of the Holset bandwagon soon. Looking to buy the hx35 that's in the classifieds right now. hx35 with an 18cm compressor housing. going on a 12v.

      any advice for starting out?


      This is a fantastic thread, btw. Thanks so much for all the info posted up.

      18cm compressor housing
      4" inlet
      2.5" v-band out
      3" v-band hot side

      if that helps at all...

      It's what, 6 lb/min difference between a 7blade and 8blade - ignoring all the vgt ones?

      that's what they say...but see my 8blade measured 56mm inducer 82mm exducer... the 7blade measured 54mm inducer and 76.2mm exducer...so i bet the flow is about equal.

      BTW are you coming to h2o???

      Meh, I thought I missed it. If it's this weekend, no. I already made plans to go out. I was hoping to take the scirocco to the event but I still can't get the oil to stop leaking so I've given up on that.

      send it with the 20v head flange. I have a compound turbo system to build.

      Now to decide. for the small charger do I want a 3071R or a small16g LOL

      typo, my bad. My concern is the 16g compressor housing won't flow enough for compounding with the hx52. I know the .63ar 3071 housing will flow well enough. I know the small16g is a 300is hp turbo, the big 16g is a 350ish turbo (at the cost of much later spool), but what sizes are the turbine housings?

      it's a TD05H turbine...the evo3 compressor will flow enough.

      I like it better when you tell me.

      It actually would be nice if you weren't the only VW guy to run a 16G.

      I know I've swapped a small 16g for a 20g before and it's not too big.

      Q.....

      got some partz donated for the rabbit.

      3.0L V6 Audi FULL LONG BLOCK MOTOR with complete harness and all.

      along with motor, a BIG Holset VGT turbo. the same turbo doing WELL on the I-5 2.2L Audi motor in the Audi car.....

      oh yeah, and a VEMS Ecu, too.

      so you think its worth pursuing a RWD mid engine build with this stuff? or should i still go ABF clone etc?

      we been doin some playin with the VGT stuff, and we have some sort of method to it. and its working....

      HOLLA!!!!!

      How are you controlling the vanes in the turbo or are they open all the time?
