    I prefer not to hijack this thread, But I do have some results with the .86 rear that I would like to show, my reply is in my high flow thread. http://www.skylinesa...ost__p__6753492

    For the SS1, It was too small for a Rb25det, I only recommend it for Rb20/SR20 det engines and they works well. I did built a .86 version of it and it appeared that compressor went out of puff around 5000RPMs resulting a sharp dip in the power band maxing out similar power level to the .64 52T and 56T 76mm wheels were also trailed, the EGT shot through the roof. It was a long project but the .86 version did ended up working and refined. the development and testing blog is in this thread if any one like to read, the final version is called the SS1PU.

    This should be very close to what a 2535 would preform on a Rb25det (my turbine wheel is one trim larger). Its bit small for the Rb25det motor but good for a Rb20det. 279rwkws = E85, 243rwkws = P98

    Oppz thought this is a coil pack when I saw yellow jackets. yes I can trail ignition moduels as well. Its for a S1 R33
  5. hypergear
    I will be interested to help you out, test them fully and post results. But bear in mind I did have red jackets which lasted 5 dyno pulls before they stuffed. So I hope this is a split fire equivalent rather then different colour same sht. I will be happy to send them back to you after trailing, but not interested of paying for them.

    Its actually very fast, the power delivery is so gradual theres hardly any wheel spin. I'm getting some mickey thompson drag tyres and hitting the strip soon.I think this one can get into the 11sec mark

    10cm turbine. I originally wanted 400rwkws out of this within usual rev range. So it is on the large end. I'm building one more in 66mm, which should drop it back to around 380rwkws mark before 7000RPMs while gain 200RPMs of response. Alternatively have a look at the new roller bearing G3 and SS2 see if that is a better turbo for what you need.

    Since this is about TDxx related thread so I will post all TDxx related results here including the turbochargers that we've built. The ATRSL25.5 (HG re-engineered T67), just maxed out at 399rwkws on mine with stock cams. Tried every thing to get that extra 1kws to crack 400 and it just won't do it. Still the highest on Trent's library for stock headed Rb25det. Looks laggy but it is very fast on the road. How ever for a street car the ATR43SS2 and ATRSL20.5 is a better performer.

    Same spec as above ^^^^^ Results from Ball bearing G3 with updated comp profile: E85 high mounted externally gated: Maxing out at 365rwkws I've also done one more run with the The ATRSL25.5G. Little bit pissed as I'm missing 1KWs reaching 400rwkws. Maxed out at 399.1rwkws. Need bigger cams for the full potential of this turbo. Still, this is the highest power ever archived on stock cam from Trent's dyno library.

    Results from Ball bearing G3 with updated comp profile: E85 high mounted externally gated: Maxing out at 365rwkws VS the older G3:
  12. hypergear
    Ok I will use same profile that I've done for ssxricho, it will have very similar response to stock while produce more power and torque with a very wide power band. Dyno reading and reference is at: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page__view__findpost__p__6352727
  13. hypergear
    Other thing comes to mind is factory manifold restrictions. So fitting a massive turbocharger on it isn't going to deliver its full potential. Better of with some thing useful and responsive.
  14. hypergear
    no worries. So do you want as much power as possible out of it or preferably stock response?
  15. hypergear
    Well. while engine's running, oil washes the bearings and shaft all times which takes the heat away. So the bearings are not much hotter then the actual engine oil. The only reason bush bearings are made out of brass or browns and some in aluminium is because it doesn't stick or rust together with the steel shaft and bearing housing. None of the BB or bush turbos trailed on my car has been water cooled, Both me and Trent thrash the crap out of them on high boost as a part of testing, and I have not seen one fail. Garrett BB must be water cooled, but not all BB require water cooling, it depends on the bearings how the setup of the chra system.

    Its the profile in the housing. will still be using original cast G3 comp wheel. So the modification can be carried out on any G3s easily (or freely). The billet wheel was from a SS3 I made a roller version of that as well.
  17. hypergear
    For the G2.5/PU high flow I can only mod it into roller bearings but this comp profile is only suitable for G3. The new G3 has a different comp housing profile. made to accelerate the discharging velocity, I can definitely feel the differences on road. The effects of it on top end power band is unsure so will hit Trents for one more dyno run.
  18. hypergear
    ^^^^^ Updates on the G3 profile. I've done a trail run with the G3 today using compressor assembly above with roller bearing cartridge I have to say it is amazing. the response is at least 300RPMs more advanced with heaps better throttle response. Any one with a current G3 in Melbourne is more then welcome for a test drive. Will be hitting the dyno next week for an comparative run against original G3. Once done I will be happy to swap it with a current G3 customer at no cost.
  19. hypergear
    Yes when they are assembled brand new the bearings are dry. Once oil goes in it will be fine. This is some modifications done to a G3 compressor housings that is made to accelerate the discharge velocity. Will do some trail on that soon as long with roller bearing assembly.

    Thanks for the support, if you are happy to send yours in I will give you a special price of $600 for one unit only. and I will make sure it out performs whom ever's $800 2nd high flow. PM through once decisions made.

    The ATRSL20.5/25.5/STDSL220G are all based in a 10CM turbine SS1PU is in a .86 turbine SS2BB is in a .82 turbine. All on externally gated setup with E85 Fuel.

    GTScott: Sorry won't be able to BB SS1PU, make no differences either way. Reading below contains the ATRSL220.5G, SS1PU, STDSL220G, and SS2BB.
  24. hypergear
    Compare to the older ball bearing setup, the difference in oil drag won't make enough differences that can be picked up by the dyno. I would call the latest more reliable, as harmonic vibration separation has taken into account. means the shaft harmonics is not affected by engine harmonics while both are spinning at high speed. I've spent many late nights and time getting that working. 89cal: The engine fitting has been sent. See how it goes, send it back for upgrade if there are any issues. This is SS2 Ball Bearing V SS2 bush bearing. Please note today's dyno run used an proper externally gated setup while the older run had an external gate plumb back setup. There shouldn't be any differences in top end assume both runs are based on the same setup. On the same time, evidence in differences between plumb back and atmospheric ventilation.

    Further updates: Today I've trailed our SS1PU and Roller bearing SS2. Both Externally gated and E85 Results are below. SS1PU maxed out at 322rwkws with peek boost of 20psi. This turbo is super responsive as usual. The Roller bearing SS2. I believe This is probably the best turbocharger that with the perfect balance of power and response for a stock Rb25det. brilliant on road driveability. It maxed at 374rwkws with 22psi of boost. We compared few runs against it including our new ATR-SL20.5G, 25.5G, as well as Bush V BB. Will upload bit later.
