    I got a bolton version of a prototype G3 including oil line for $800 if interested. It was maxed out at 347rwkws on E85 internally gated on 22psi and 352rwkws external on 24psi. Would be good for about 270rwkws mark on pump 98 fuel on mild boost level. and fairly responsive as a daily. details, photos and dyno reading at: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-473

    Same price. Just more power and slightly laggier. That is good for externally gated setups.
  4. hypergear
    No the SS3 is about 300rpms laggier then SS2. The power / response trade is: 1KW:10RPMs. Take the SS Alpha trailed for example: SS2 makes 383rwkws 20psi by 3500RPMs SS3 makes 407rwkws 20psi by 3800RPMs

    Not overlaid you will have to read them. Results trailed in mine is only in the Alpha version. Normal version would be 300RPMs behind. SS2: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-395 SS3: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-409

    SS3 would fetch to 400rwkws, SS4 to 435rwkws, SS5 to 490rwkws.

    They are .82 rear. Super responsive on a Rb30det
  8. hypergear
    Its fine. Makes the same power on much lower boost on a Rb30det motor.

    I've been done for 5 times, Its not too bad in Vic. Go to EPC center in Mcloryd. Put factory dump pipe and exhaust back on and make your engine bay looking standard. They will do a emission and noise test and it will be ok.

    SS2 external gated results: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-333 http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-351

    Might want to dummy it up first. I've had a HKS low mount manifold that came with a TA45 turbocharger. its a tight fit, only few mms from hitting the engine mount. If that is the case then you might want to change the turbine housing's entry flange then bolting on an adaptor in between.

    Go to www.taobao.com You can get Fake very thing that looked just like the real one. I've bought a Knock box, Turbo smart BC, and AEM ECU while I was in China working on that Kia project. Every single one that cam at my door are useless fake.
  13. hypergear
    I usually make a base model and tune it against its older version. If it is a success then integrate the SS compressor for better response. So both models gets upgraded.

    Unfortunately building turbochargers isn't just about turning lathe, people isn't just buying a turbo, they are buying their desired HP goal. Ensuring the outcome I must not only be an excellent engineer, the engineering must be closely related to the power generating subject which on SAU is a Rb25det motor along with all of its components. Yes I have a book of dyno sheets contain 1806 pages. that recorded the behavior of a Rb25det in many different aspects, its very useful in directing the shortest path archiving certain performance goals.

    Results for above:
  16. hypergear
    Pretty sure Its a Fake. I'm also seeing Fake ECUs, Turbosmart parts, HKS parts, and counterfeit of many known brands in China.
  17. hypergear
    Sorry I didn't get any names in the package, I assume you are the guy from WA correct? if so then yes it has been received. just more power in this upgrade?

    The cams I used was 264 dur / 9 Tomei from CJmotor, and only CJmotor has them. That was a waste of time and effort, made 3kws of power differences for 400RPMs of lag. For the HP level expected, standard cams works best. details are at: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-452

    You mean flange size? T3x has bigger flange size. It does not represent the A/R or the volume of the turbine housing.
  20. hypergear
    OP6 and 21U run the same high flow profile. and makes about 30kws differences in power. Run larger wheels also has a "bigger housing" affect. Means it enables the housing to discharge air faster, less back pressure, less heat. On the same time needs higher velocity to spool. Which is lag. Just like as if I can drop in a GT35 turbine in a .64 rear it will be making 300rwkws+.
  21. hypergear
    Cost to high flow is same. All the results has been indexed on page one of my high flow thread. Along with many other. 21U result is at: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page__st__7000 Op6 result is at: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-461 Note 4WD systems usually creates a bit more drag, acts very similar to higher dyno ramp. Which usually ends up with better response and less power, probably because the combustion discharging temp is higher under greater load..
  22. hypergear
    Unlikely to be chocking, just like high flowing a small R33 turbocharger using factory housing and get full potential of that. I just didn't like lag. I've fixed the timing chain, and ordered a brand new VCT cam gear form US. Will be back on the dyno very soon.
  23. hypergear
    T2. in .86 can support that sort of power no issues. But why would you want to do that?
  24. hypergear
    I think the SS2 or a OP6 high flow will suit your car better. Reason is I've found out that your car is a AWD GTS4. By experience not only that they are 12% lake in power to the RWD Skylines, they also run the turbine end hotter. The end result will be more successful with a larger rear housing, that makes the engine much happier too. Other thing need to be understood is turbocharger isn't magic, making 20psi by 3400rpms requires high exhaust gas velocity in low rpms, which does not satisfy the flow requirement in upper rev range or compensate for high boost. There for most 500HP rated turbochargers kicks in 20psi region around 4000RPMs mark using a larger turbine housing. Solution on the extreme side is high temperature variable turbine geometry system, heat resistant silicon nitrate ball bearing system and high efficiency compressor wheel (ATR43SS-Alpha system). On this setup we can have 20psi by 3500RPMS, make good power while not chocking the engine. Sadly this turbocharger so far can only work on an externally gated system, complicated to build and expansive.

    Another option is run the ATR28G3 turbine wheel. This is also a customized turbine wheel that I've made to suit a T28x bearing housing originally for high flowing Stock T28. This CHRA isn't very popular on the CA/SRs how ever used often on the CT20 Supra twin high flows. It appears to be 500RPMs laggier on paper when its first trailed in 2009. Now using FNT turbine and SS1.5 billet comp wheel I might be able to gain 300RPMs in response to what it was, using a .64 turbine getting 20psi by 4000RPMs while not chocking the SR20det motor in upper revs. Will update photos once its been made.
